Hi, can someone advice me about time history analysis, when we should use response spectrum and when to use a time history analysis

whether it depend on the building height? the building seismic design category or?

I'm very appreciete if someone willing to advice

Thanks

Dear Eko,

These are different analysis techniques, simplest is LSA (linear static analysis) which is normally used for simple/low rise building. When there are sophisticated structures having irregular masses or varying story heights or very high seismic area  advance analysis are required to get the more accurate and realistic results which may not be predicted with LSA like plastic hinges . Advance analysis like THA need time and expertise which might not be suitable for simple structures but for high rise and important structures THA may be used. If you need specifically for a project, share the details, i or any other senior may respond more precisely.

Regards

    • *SEFP Consistent Design*<br style="color:#272a34">*Pile Design*<br style="color:#272a34">*Doc No: 10-00-CD-0005*<br style="color:#272a34">*Date: Nov 21, 2017*<br style="color:#272a34">
       

      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.

    • 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

    • 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.

      How can I transfer response spectrum loads from etabs to safe

      First of all my apologies, if my question seems stupid because of my unfamiliarity with the topic.
      When defining response spectrum load case in ETABS, we have three directions; u1, u2 and u3.
      Lets assume the excitation angle = 0 and building principle direction is u1
      So I will apply response spectrum function (per IBC 2006) in u1 direction by a scale factor.
      My question is why we don't apply u2 and u3 in the SAME LOAD CASE.
      My understanding is, according to WILSON in his book on STATIC & DYNAMIC ANALYSIS, CHAPTER 15. The response is calculated for each direction separately. Then this response is combined by different methods (CQC, SRSS etc) which is called MODEL COMBINATION.
      In CQC method response in 2 directions is assumed to be a portion of 1 direction means S2=a.S1
      Where a = 0 to 1.0, recommended value is 0.50 to 0.85
      I know in EQ building has only one principle direction. Although EQ can hit from any direction but there is always one major direction. or you can say major acceleration in 1 direction. Lets say u1.
      As in CQC method the response in other direction will be some portion of response in major direction. I also know that If we have equal spectra CQC is reduced to SRSS method which is independent from the excitation angle theta.
      My confusion is we will do MODAL COMBINATION (cqc or srss) only when we want to combine u1, u2 and u3 at the same time. But if we are applying only u1 in one response spectrum load case, then we DONT have to do modal combination. It is the same thing as in CQC S2=a. S1. Now in this case a=0. so S2=0. All we have is only response in u1 direction.
      Then in my building models what i do? include u1 and u2 both in one load case or in separate load cases?

      Hello everyone, I hope all of you will be fine. In etabs when we apply Response Spectrum loading on a multistoried building with 2 basement floors. At what floor level this loading will be applied as in equivalent static seismic analysis, we can apply EQX & EQY on any floor we like as this option is available in etabs but the problem is with response spectrum and time history analysis. please if someone knows and have the experince, share it i shall be very thankful.

    • 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.
