    The scale factor Ig/2R is required only for versions before 2017. From 2017 version of etabs the I/2R is included in the function itself (we need to specify Z,I,R during defining the function). So now the SF to be used is just ''g'' in appropriate unit

    In calculating the Aw (area of wall) you cannot multiply its length with its height (you did 3.25 x 3.5=11.375m2). It is clearly stated that Aw is the effective cross sectional area of wall in first sorey of building, therefore you should have multipiled its length with its thickness, not with its height. (so 3.25 x 0.3 =0.975m2) this value you should have been using.
    Anyway good job.

    Sir, while defining LOAD CASE : RSx ,
    in LOAD APPLIED. Can we account the effect on RSx by 100% x-dirn load and 30% load on y-dirn?
    LoadType LoadName Function ScaleFactor
    Acceleration U1 IS2016h 100%*(9806.65)
    Acceleration U2 IS2016h 30%*(9806.65)
    and similarly for defining LOAD CASE : RSy ,
    in LOAD APPLIED. Can we account the effect on RSy by 30% x-dirn load and 100% load on y-dirn?
    LoadType LoadName Function ScaleFactor
    Acceleration U1 IS2016h 30%*(9806.65)
    Acceleration U2 IS2016h 100%*(9806.65).
    And on NEXT ITERATION
    for RSx:
    LoadType LoadName Function ScaleFactor
    Acceleration U1 IS2016h 100%*(Multiplying Factor for U1*Previous ScaleFactor)
    =a
    Acceleration U2 IS2016h 30%*(Multiplying Factor for U2*Previous ScaleFactor)
    =0.3b
    Similarly on RSy:
    LoadType LoadName Function ScaleFactor
    Acceleration U1 IS2016h 30%*(Multiplying Factor for U1*Previous ScaleFactor)
    =0.3a
    Acceleration U2 IS2016h 100%*(Multiplying Factor for U2*Previous ScaleFactor)
    =b
    (Here, ScaleFactor for U1=BaseShearEqx/Shear for RSx,
    ScaleFactor for U2=BaseShearEqy/Shear for RSy).
    Kindly, answer this regarding IS codal provision on this accounting for seismic load of 100% in one direction and 30-40% in orthogonal direction. ThankYou from Nepal.

    • @akshaykamath1190
      @akshaykamath1190 4 года назад +1

      we use 100% in 1 direction and 30% in other direction only when we have non orthogonal frames rit. I mean when we have column oriented in 45 degree or other degree.. Here all columns are orthogonal. No need of going with that 1.5dl + 1.5 ( eqx+0.3eqy ) combinations.

    Respected Sir,
    If vertical response spectrum is not present in seismic code of design, then out of these two function, which function should be used in linear time history analysis
    1) Scaling of vertical ground motion time history as 2/3 of horizontal response spectra.
    OR
    2) Scaling vertical ground motion time history as only horizontal response spectra.
    Looking for your guidance and support.
    Thank you.

      No. According to IS 1893-2016 if your structure falls in zone 2, 3 and 4 and in zone 2 above 15m you should do dynamic analysis. It again depends whether the client is intrested or not. For high rise building we do dynamic analysis, if small G+3 we don't do, Static Analysis will suffice.
