Building Overview
Setback vertical irregularities in the building is one condition where there is a sudden change of upper stories bays because it has a smaller number of bays than the lower stories. The upper part is regarded as tower structure, while the lower part is regarded as base structure. The setbacks could influence the discontinuities in the mass, stiffness, and structural strength distributions. Hence, the analysis on setback buildings is necessary because its existence has considerable effect on structural response under seismic excitations. In this example, two sets of experimental tests setback RC buildings were modelled to show the accuracy of STERA_3D. These two specimens are representing two type of setback buildings, namely towered setback [1] and stepped setback [2].
