Suggest Some Institute For Learning Civil Engineering Software In Islamabad Or Else Where?

Recommended Posts

Otsruc.com is very good site to learn structural software ETABS/SAFE/SAP etc. developed by esteemed fellow Rana Waseem he is very good practicing structural engineer with excellent command on software.

 

Along with joining courses you have to work with the software and only software is not the structural engineering you must work on the basics of structural engineering. Just modelling on software and getting results is not engineering. this exercise can be easily done by a matric pass student as well if he is trained to use the software. 

 

Engineers are required to grasp knowledge behind the software. Engineering judgment comes with practice and working under kind seniors who guide you through the design process. All young engineers are suggested to be attached with seniors and request them to guide and mentor you through the process. And seniors are requested to mentor at least 1-5 freshers:-)

      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.

      Hello every one
      i modeled a flat plate with SAFE and after i run the analysis i got different results when i compare FEM with strip Forces for both M11 and M22
      these is so much different .
       
      one more thing  , i solved the same example with direct design method and when i compare it with Strip forces from SAFE there are good agreement , but when i compare it with FEM result by SAFE there are big differences !!
      does any one have information
      thanks

      Salam Alaykom All,
      I am modeling a refugee camp on Etabs. I have over 20 buildings to be modeled, each 5 share the same raft foundation , and each raft foundation is no more than 3 meters away from the other. For simplicity I modeled all 20 buildings in the same Etabs Model to Calculate the forces on the raft foundations. My question is :
      1_ Will the  Raft Foundations be Affected by each other , knowing that the buildings they support arent connected in any way?
       
    • By Ahsan Kazmi
      I have modeled B+G+6 story in etabs and exported its base with 9" thick and 12 feet high  RCC wall with option (export floor loads plus column and wall distortion). In Safe initially i defined raft and soil support properties. after analysis the minimum soil pressure was out range (7 ksf) while my allowable limit was 2.25ksf. Then i selected all the joint points of wall and assigned them fix supports the soil pressure suddenly reduced to almost zero value. Question is that which strategy of modeling is correct? Secondly when we export wall from etabs to safe its property changes to beam why this happens?
      Model is attached below.
      Raft 12.FDB
    • By Ahsan Kazmi
      How to check the soil pressures in SAFE? What is difference between min and max pressures? and what is allowable limit?
