Understanding Reinforcement Output ETABS

Recommended Posts

Assalamualikum,

what is the meaning of Longitudinal Reinforcement,Reinforcement percentage in ETABS output.
Say, a column reinforcement percentage is 2.3%
what is the meaning of it?
again,
say, longitudinal reinforcement is 4.2
what is the meaning of it?
Why do i need to know this parameter?

Wasalam,

Dear Shamim,

These are basics of RCC design to know the required reinforcements, if reinf %age is 2.3%, your column size is 12"x12"(say) you will get longitudinal reinforcement as 2.3x12x12/100 = 3.312 in^2, now you can convert this 3.312 into different number of bars, if you are using #6 bars its area is 0.44in^2, Number of #6 rebars= 3.312/.44 = 7.52 make it 8 #6 bars as longitudinal bars in  RCC Column.

Thank you so much brother.
what is the meaning of Longitudinal reinforcement 4.2 or whatever a Numeric value?

Longitudinal Reinforcement= Rebar parentage x section of column
is it??????

      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:

      Overview


      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.

    • I am suppose to design a pile foundation for a machine weighing approximately 50 tons and with an operational loading of 100 tons. 
      I ll appreciate your help in terms of guidance & provision of notes...  
       
      Thank you..

    • 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.

      Thanks

      i am facing problems in shear wall design .what are the pier and spandral ?what will be the difference when we assign pier or spandral? without assigning these the shear wall design is incomplete .

      i am taking about etabsv16

      someone have document about shear wall design plz provide it 

      thank you

    • 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.

    • Assalam o alaikum.
      According to ACI 12.5.2,
      development length for fc' = 3000, fy=60000, for normal weight concrete and epoxy less reinforcement, The required development length comes out to be
      for #3 = 8.2 inch
      for #4 = 10.95 inch
      for #6 = 16.42 inch
      for #8 = 21.9 inch
       
      And if in my case, ACI 12.5.3 is not fulfilled, it means now i have to provide ldh as mentioned above. ldh is STRAIGHT EMBEDMENT LENGTH + RADIUS OF BEND + ONE BAR DIAMETER as shown in figure attached. Now my question is, if in my case, main reinforcement of beam is of #6 and #4, minimum column size required will be 18 inch and 12 inch respectively. Lets say by any means, i can not select #4, #3 bars and size of column where bars are to be terminated is 12 inch, how to fullfil this development length???

    • Dear all,

      I am trying to design shearwalls through ETABS with temperature load applied over shell. At various location, spandral section fails in Shear due to temperature and piers (sometime in shear, mostly in flexure).  (See Attached Image)

      Certainly all the problem in Shearwalls are due to temperature. I don't want to increase cross section of spandral or pier at some location just due to temperature load case as it will appears non-uniform with rest of the wall. 

      I have seen stiffness modifier affect distribution of forces and also rigid/semi rigid daiphragm assumption. 

       

      Can anybody guide how to properly design the shear wall with temperature load applied in ETABS or share any similar experience. Thanks in Advance.

      Hello
      I design flat slab in ETABS and cracks width in the slab larger than maximum allowed by standard. Is it posible to provide larger amount of the reinforcement, which ETABS will use to check the cracks instead of the required reinforcement which ETABS calculated for flexural design?

      Have a nice day.

      Can the slab bottom reinforcement pass below inverted beam bottom reinforcement?
      Otherwise the slab bottom reinforcement mesh will be lifted up atleast 2.5", thus reducing the design effective depth.

      Dear Members
      I am working on a project site where Column Reinforcement is as shown in the file. 
      The Columns (C6 to C20) are going from +12'-0" to +48'-0" un-braced and without any slab at intermediate levels. The slab is at +12'0" and +48'0" level.
      The Reinf is changing and larger dia bars are provided on top.
      I want to ask that is it alright and what is the possible explanation of changing the number and dia of bars in-between ?

      Regards

    • Dear experienced fellows  After completing the model in Etabs, what's the next step for foundation design. What i have learnt is that: 1- Do we have to import the Edb file into SAFE? I didn't get this point of modelling foundation in Etabs coz i have learnt that foundation is modelled in SAFE only 2- we have to get the forces value i.e Factored axial loads and bi axial moments from reactions in ETABS and design foundation in SAFE accordingly? Thnx in anticipation

    • There are three spring values we normally use in 3D structural analysis... kx, ky, and kz (being kz as vertical, and horizontal springs particularly against lateral loads) vertical springs are calculated as discussed above or as per geotechnical report... horizontal springs are calculated as half of vertical spring value Kx = Kz/2 Ky = Kz/2 I don't have any backup literature (for now)... one can dig the internet or consult a geotechnical engineer/company (this is mostly their expertise),... though I designed few structures some 20 years ago in SAP 90 (few structures in FJFC bin Qasim, Rousch power plant, Bestway cement Hattar) and till-to-date they are still standing and operating perfectly please post here... if anyone find some reference to that
    • Please see the following:   Thanks.  
    • For residential construction, basement walls act as propped cantilevers because of ground floor slab. You can model your wall as a propped cantilever and design for those forces. Also, check these topics out: The last post on the above linked thread has a solved example too. and this: Thanks.  
    • The only reference I know in this regard is ACI Detailing Manual. However, as a matter of doing structural design, you can bent bars up if you can show by analysis that the reinforcement configuration using bent bars would satisfy moment demand in the beam.  Thanks.
    • Hinges at both levels only can lead to the loss of gravity-load-carrying capacity.
    • I am designing a retaining wall (cantilever) for a basement. I have applied only 2 ft additional depth as surcharge load other than the earth pressure load. The height of the wall is 10 ft. My stability checks are satisfying for foundation width of 6.83 ft (2 ft heel, 9'' stem, 4 ft toe), which i think is very high. What can i do to reduce the dimension of my wall footing?
    • Thanks for your reply. Can u please help me in providing reference from codes for its detailing, as I have to use in one of my projects. Thanks.
