Diaphragm In Seismic Design

Recommended Posts

Assalam o alaikum,

ACI 21.11.1 tells about diaphragms in seismic zones. My building is in zone 4 and it is frame structure. i have provided SMRF. Is my slab going to act as Diaphragm? Since diaphragm means elements that transfer horizontal forces to vertical elements. and slab becomes cause of major horizontal inertial force and it transfer lateral forces to beams which transfer to columns. Is my slab diaphragm??

    • 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.

      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.

      aslamwalekum to all,
      when we need semi rigid diaphragm , i normaly take rigid diaphram for beam slab system , i got a vetting project (model made on ETABS 2016) , in which flat slab are used and semi rigid diaphram is assign , A/c to IBC 2006 , concrete slab with thickness more than 1.5 in , not consider as flexible diaphram , here is the code refrence.
      1613.6.1 Assumption of flexible diaphragm. Add the following
      text at the end of Section of ASCE 7:
      Diaphragms constructed of wood structural panels or
      untopped steel decking shall also be permitted to be idealized
      as flexible, provided all of the following conditions are
      1. Toppings of concrete or similar materials are not
      placed over wood structural panel diaphragms except
      for nonstructural toppings no greater than 11/2 inches
      (38 mm) thick.
      2. Each line of vertical elements of the lateral-
      force-resisting system complies with the allowable
      story drift of Table 12.12-1.
      3. Vertical elements of the lateral-force-resisting system
      are light-framed walls sheathed with wood structural
      panels rated for shear resistance or steel sheets.
      4. Portions of wood structural panel diaphragms that
      cantilever beyond the vertical elements of the lateral-
      force-resisting system are designed in accordance
      with Section 2305.2.5 of the International
      Building Code
      here in my case slab is 8 in thick , so can it be act as flexible diaphragm.
      i belive for metal decking , i can use semi rigid diaphram , but not for 8 in thick flat slab
    • By Aye Min Khaing
      What is difference between Rigid and Semi rigid diaphragm. I think if we assign semi rigid, We don't need to consider accidental torsion i.e 5% eccentricity. If we assign rigid, we must consider accidental torsion. And next question is difference between XCM and XCCM in case of rigid diaphragm. What is MassX and MassY. How to calculate XCCM and YCCM. And how they work.

      Dear All, 
      Could anyone suggest me assigning diaphragm like assigned in attached pic is correct for this building. If it is correct then how could we apply torsional irregularity in static load cases (earthquake case eccentricities override). I can calculate and apply it in simple building but in this building there would be two options of diaphragm( D1 & D2) in eccentricity override option in etabs ( If my assigned diaphragms are correct). which one i need to select.

    • By abdulqadeer29
      While purpose of assigning diaphragm is to transfer inertial forces during earthquake to vertical members . There is general practice which I am following for quite a long time,  that we most of the time don't consider inclined members like stair and ramp. i model them as horizontal slab.
      I have recently observed that there is a difference in the result while considering them as inclined members.
      My question is do we have to assign diaphragm to these inclined members (ramp or stair case)?

      I am writing this article about a very important, but mostly neglected topic of flexibility of diaphragm. I used to assume that all reinforced concrete slabs can be treated as rigid diaphragms. But as it turns out, only the slab with span-to-depth (depth is length of slab in direction of lateral loads) ratio of less than 3 and without horizontal irregularity can be treated as rigid diaphragm. The more important thing is that the span-to-depth ratio and horizontal irregularity is not the only criteria and one other factor also needs to be kept in mind before assigning rigid diaphragm to concrete slabs in numerical model of building.

      Another important concept that I learned, and it was a moment of epiphany for me, is about TRANSFER diaphragms. I had posted a topic “Amplification Of Forces In Etabs” earlier in this forum but we were not able to reach at a satisfactory conclusion. Now, I have the answer to that query: Back Stay effect. Another article is required to explain it , and this concept is not discussed in this article. This article is about flexibility of diaphragm.

      Diaphragms are horizontal members of the lateral-force resisting system of building structures. Their function is to distribute inertial forces, generated at its own level, as well as other levels, to vertical members of lateral-force resisting system.

      One kind of diaphragm only distributes inertial forces generated at its own level. This kind of behaviour is observed in buildings where there is a continuity of vertical members of lateral-force resisting system: building should not have a setback or podium at lower levels, or below grade levels. The other kind of diaphragm, known as “Transfer diaphragm”, not only distributes inertial forces generated at its own level, but also re-distributes forces coming from upper levels. This type of behaviour is typical of a building having setback or podium at lower levels, or below grade levels. Transfer slabs can attract huge forces due to a behaviour dubbed as BACKSTAY EFFECT.

      Now, coming to the issue of flexibility of diaphragm. According to ASCE 7-10,

      In addition to considering aspect ratio and horizontal irregularity as a basis for assuming concrete slab as a rigid diaphragm, the relative stiffness of adjoining vertical lateral load resisting system. Buildings with shear walls at ends and flexible frames in between are the ones where the assumption of rigid diaphragm leads to underestimation of drifts and erroneous distribution of base shear in vertical as well as horizontal direction (1)(2)(3); shear forces in middle frames can be reduced to 23% if rigid diaphragm is assigned in the model (1) for buildings with this type of structural configuration.

      M. Moeini et al. (2008) (3) conducted a parametric study using numerical analysis and proposed formulae that predicts the error associated with assuming concrete slab as rigid diaphragm. They also concluded that for buildings, without shear walls, rigid diaphragm assumption is suitable for irregular buildings as well. But, for long and narrow buildings with shear walls at ends, the assumption of rigid diaphragm is not suitable.

      The objective of writing this article was to warn engineers about the tendency of blindly assigning rigid diaphragm to concrete slab in any type of building configuration. The result could be underestimation of forces as well as drifts.

      The article is not finalized and would be completed in coming weeks.

      Can anyone tell me while assigning the diaphragm when we have to choose the semi rigid or rigid. What exactly it does with the structure in ETABS? 
      As far my understanding I am applying rigid diaphragm for concrete structure and semi-rigid for steel structures / car park structures.
    • By jammer3425
      what is the purpose of assigning diaphragm b4 running analysis of concrete structure in ETABS and what type of diaphragm is required to be assigned to the structure as it shows us two types rigid and semi rigid. what role does these factors governs or play in the design of the structure?
