Bridge Girder Collapse during launching

Recommended Posts


Girders of a bridge during launching collapsed. it is reported it happened due to heavy winds during launching of the girders,links for further details are attached.

What i got is that the girders toppled due to wind or any other mistake during launching and their inertial angle changed. Definitely, girders were not designed this way so collapsed in flexure at center region as both ends of girders are still on the supports.

    • Hi guys just to discuss with you my understanding of crack widths in Environmental structures according to ACI. 



      Normal structures



      1. ACI 318-95 based on statistical method of Gergely & Lutz 1968 limits Z based on exposure. We are calculating crack widths here. (Normal structures)


      2. ACI 318-99 proposed limiting the spacing and removed actually calculating the width and also removed the exposure conditions. For example for beams and one-way slabs s (in) = 540/fs -2.5cc or in other words limiting the fs=0.6fy  (For normal structures)


      3. ACI 224R-01 references method 1 and 2 above and 3 european codes.

      The most confusing part is the table in which Nawy suggests 0.1mm crack width for water-tight structures. The whole document is for normal structures except this line. And people are following this line and refer to this document for water tight structures. I mean its just a suggestion and by the way this method 1 is obsolete now since ACI 318-99 (see point 2 above).



      Water tight structures



      1. ACI 318-08 states clearly that for watertight structures ACI 350-06 codes should be used. 


      2. ACI 224.4R-13 also specifically states that for watertight structures walls in section 7.4, we should use ACI 350-06. 


      3. ACI 350-06 for water tight structures does not recommend calculating a number for crack width but rather limiting max steel stress in bars to be 20k ksi or fs=0.33fy for normal conditions.



      To sum it up, 


      Philosophy of crack width control is not to calculate probable crack widths but to limit the max stress in steel bars.


      For normal structures: fs=0.6fy and for water tight structures fs=0.33fy

    • Hi

      I want to know the use of diaphragms in etabs. i discus many people who are use etabs but i can't get justified answer about the application of etabs.

      I read the Technical reference  of  Etabs, where they write about Diaphragms. i get two type of diaphragms (plate or shell and joint or beam). 

      My question.

      1. When do i use Shell diaphragms (if floor present ) 

      2.When do i use joint diaphragms ( grade beam level where no slab are provide) 


      NB: Diaphragms use to transfer the lateral load to the resisting element ( frame such as column. beam,shear wall)

      This article is intended to cover design of piles using Ultimate Limit State (ULS) method. The use of ULS method is fairly new for geotechnical design (last decade). The method is being used in multiple countries now (Canada, Australia etc). The following items shall be discussed:


      Geotechnical Design of Piles (Compression Loads, Tension Loads and Lateral Loads)

      Structural Design of Piles (Covering both Concrete and Steel)

      Connection of Pile with the foundation (Covering both Concrete and Steel)

      Pile Group Settlement

      Things to consider


      1. Overview

      Piles provide a suitable load path to transfer super-structure loads to foundation where shallow foundation are not suitable - this can be due to a number of reasons like existing space constraints or suitable soil strata is not present immediately below structure. Other uses can be to meet design requirements like to have reduced settlement etc.

      This article shall cover the use of straight shaft cast-in-place concrete piles and straight shaft driven steel pipe piles. There are a number of additional piles types like belled concrete piles, precast concrete piles, screw / helical steel piles etc but the discussion to choose a suitable pile type is not in the intended scope of this article. The article is intended  to discuss design requirements for straight shaft piles only (both concrete and steel) . The aforementioned topic about pile selection is a very diverse subject and requires a separate discussion on its own.

    • Material behavior can be idealized as consisting of an 'elastic' domain and a 'plastic' domain. For almost 200 years, structural design has been
      based on an elastic theory which assumes that structures display a linear response throughout their loading history, ignoring the post-yielding
      stage of behavior. Current design practice for reinforced concrete structures is a curious blend of elastic analysis to compute forces and moments, plasticity theory to proportion cross-sections for the moment and axial, load, and empirical mumbo-jumbo to proportion members for shear.

    • AoA all,

      Is it mandatory to do column concreting upto the soffit of the beam in a single pour ?

      What code says about the construction/cold joint location in column ?

      Majority of the contractors are pouring the column concrete upto the soffit of the beam (full height of the column), some contractors leave the column height about 9" to 12" below the beam level and then fill this 9" to 12" column height with the beams & slab concreting. On one site column concreting was stopped at the mid height and the remaining half was filled on the next day.

    • Please clarify the following confusions one by one:-


      1. If we run P-delta analysis in ETABS, then should we ignore stiffness property modifiers for beams and columns? I have heard that if we perform P-delta analysis and apply stiffness modifiers at the same time then the moment magnification process is doubled...?


      2. ETABS considers selenderness of a column by applying moment magnification factors. If we run P-delta analysis also, does it mean that the selenderness of column is being over-estimated? I mean once the moments are magnified in P-delta analysis process and again through moment magnification process?


      Please help me understand the software myth and clarify above confusions.

      Salam everyone.
      I'm doing a study for fatigue crack growth in a steel box girder bridge. For that I need the loading history (or strain history). If anyone can share it, it would be greatly appreciated.

      Hello Everyone,
      Saw this on FB today. Thought would post. What do you think went wrong?

      I need your help in deciding whether to go for a RCC basement or Pillar foundation for home construction. I am not a civil enginer. I want the home to be constructed on a strong foundation. I have heard from someone that basement makes the home weak in terms of its foundation. For example in earthquake home with a basement can be more vulnerable to cracks or collapse. I have zero knowledge about construction. That is why I need your help.
      Should I go for a RCC basement OR pillars foundation.
      My only concern is that the home should be on a strong foundation. I am planning for ground floor and in future if needed then first floor. Please guide me which way to go.

      Dear fellows!
      I have observed that some senior engineers have not been using stiffness modifiers in their designs. What is the concept behind  i am not clear . As we design RC for strength, section is cracked and to cater for this cracked section, property modifiers are used as per
       ACI 318-11  10.10.4 (stiffness requirement)

       ACI 318-11  8.7 (stiffness requirement)

      UBC97 1630.1.2 (modelling requirement)
       so why whole section is considered in design. is there any other logic which i couldn't understand.

      Dear All, 
      I have designed the bridge between two building. Fixed at one end and roller at the other. The bridge at the roller end, rests on a concrete ledge. I have provided the expansion joint based on the formulation of ASCE for building separation. I have certain queries on it :
      1- Is building separation formulation is appropriate to provide expansion/moment joint in my case?
      2- I am trying to allow the movement through slotted holes in base plate. If my bridge required expansion is 300mm through formulation indicated in Point-1 above, should the slotted hole be twice of it i.e.  2x300mm = 600mm  
      I am still unsure as to what size the slotted hole should be ? and what governs the expansion joint of bridge over the ledge end. 
      I am relatively new to bridges. any help would be highly appreciated. Thanks in advance.

      Dear Colleagues!
      The Øresund bridge is an engineering marvel that connects the Danish capital of Copenhagen to the Swedish city of Malmö.
      A cable-stayed bridge runs nearly 8 km (5 miles) to an artificial island where it transitions into a tunnel that runs another 4 km (2.5 miles). The award-winning double-track railway and motorway opened on July 1, 2000.

      Can some body please give reference regarding torsional design of post-tensioned bridge girders? I have searched through AASHTO LRFD Bridge Design Specs but could not find a valid reference.
    • By Ali Shan
      I have modeled a retaining wall in SAP2000. I have got the moments are shear forces in major and minor directions. The wall is also carrying some concentrated axial loads over it (separated at some distance). My question is, how can I check the axial force present along the length of the wall in SAP2000? Like M11, M22, V12, V23, which component denotes the axial force transferred? Also, please give some reference of calculating RCC wall axial load carrying capacity.

      Hi guys
      In the question i have a super T girder with some reinforcement. Ques is I have to calculate compression strength in concrete block using formula C = gamma * 0.85 f'c * b (width)
      what value of b should i use to calculate this compressive force?

      using staad foundation advanced, I designed a strap footing for two eccentrically loaded columns(offset of left column=-600mm and offset of right column=600mm) of one bay, 3 storey building with grid spacing of about 14 ft in x direction and 12 ft in y direction. The dead load was about 300kN and live load was about 60 KN and earthquake load was about 40 KN in -y direction with moment about z axis 25 KNm. soil bearing capacity was 150 KN/m^3. I used the load combination 1DL+1LL and 1DL+0.8LL+0.8EL. strap beam was in x direction. I got footing size 1.75mx1.75m. footigg thickness 200mm. no of 12mm bars in x direction=6 and no. of 12mm bars in z direction=23. I got doubly reinforced strap beam with 0.53m depth and 9 inch width. bottom reinforcement=3 no. of 12mm bars top reinforcement=6 no. of 16mm bars. And for shear reinforcement it says:"Since nominal shear strength of concrete is greater than maximum shear force, shear reinforcement is not required". I just want to know are the results I got practical or is it likely that I had made some mistakes. I have doubt whether the following result in right or wrong: the vast difference of reinforcement in x and z direction which are 6 and 23 no. of 12mm bars respectively for 1.75mx1.75m footings. and another doubt is requirement of no shear reinforcement in strap beam. Please help me!

    • Hello I have a question regarding stiffness modifiers in ETABS. The code(ACI318) specifies us to use stiffness modifiers for walls column etc. What if I use 0.35 as stiffness modifier and not 0.7. What is the effect.I know that we have these stiffness modifiers based upon cracking of section and using these modifiers results in lesser stiffness thereby reductions in attraction of lateral forces.But suppose I want to reduce the lateral forces on walls therby using stiffness modifiers 0.35 for walls and not following the ACI. Thanks
    • Dear Seniors!  Anyone having CISC (Canadian Institute of Steel Construction ) manual. I need it for finding Bx (monosymmetry constant )values for steel sections. Thanks
    • Yes its a culvert with long walls and slab on top. And so it cant be designed as a retaining wall. But due to longer length, main reinforcement will be that along the shorter span i.e. height (vertical reinforcement). I was thinking it should be designed using attached formula for for FEM when performing Moment Distribution, and W will be same as we do for triangular load. I was just confused if I need to use the walls coefficient method but I guess that's for walls with 2-way action which isn't the case here.  
    • AOA!!. i want to how can load be transfer from slab to beam after analysis in etab ?? whether it can be done throught tributary area ?? Secondly, i have a sheet in which only service dead and live load has to be placed so to find service dead load of beam i have to find self weight of beam and add it ith imposed dead load which i have assign on slab in etabs... Thank you..

    • Thanks Umar.   I am need the sofware Straus 7, Can help me?
    • (ka*unit weight*height)  is the base pressure of the triangular force. You need to use ka*1/2*Gamma*h*h as the force and then multiply the force by lever arm (I think its 1/3rd (likely) or 2/3rd height - see literature) to get the moment at the base. If you have got a long wall, you should also do a check for counterforts to see if they are required or not. I am not sure why you called this a culvert, if its a long retaining wall. If you have a slab on top level, then the design would be different. Can you share a picture or a drawing. Thanks.
    • If it is designed properly, yes. What that means is that your slab needs to meet strength and serviceability criteria. You can model a waffle slab in safe and check if its reinforcement requirement and deflection are under code permissible. Thanks.
    • Ingrid, I might not be the best person for this. I have requested a tunnel specialist to join this forum. Lets see if he comes. Thanks.
    • Thanks you, Umar e Hira. Really need help!
      I have not could have good answers in my model!
      I am trying contact with you (Umar), but i did not can Regards! My tunnel is in soil.
