Hello everyone,

I'd like to share a workaround for applying vertical seismic effects in SeismoStruct's gravity load step.

Many codes require this. For example, TBDY 2018 defines the nonlinear combination as:

G + Qe + 0.2S + Ed(H) + 0.3×Ed(Z)

where G=dead load, Qe=effective live load, S=snow, Ed ...

The shear capacity calculation results for Wall15 are as follows:

Here is the example model:

If we delete all upper soreys, the shear capacity of transverse reinforcement is calculated, but if there are upper floors (Even just one is enough), the shear capacity of transverse reinforcement for Wall 15,16,17 and 18 in Floor -1 are considered as zero.

I have uploaded an example model.

In this model, the shear capacity Vw,s(Local 3) of Wall15, Wall16, Wall17 and Wall18 are considered zero for floor -1.

Hello,

In Seismobuild, when calculating the shear capacity of a wall on the lowest floor of a building model according to TBDY 2018 and TS500, the contribution of transverse reinforcement is taken as zero (0), whereas on the upper floors, it is considered. This situation occurs when the concrete ...
