Abstract
The seismic pounding risk analysis is to express, in quantitative terms, the probability of structural pounding of adjacent buildings within a specified period of time. Based on the developed approach, the seismic pounding probability of buildings designed according to the 1997 Taiwan Building Code (TBC) is investigated. The effects of site soil profile type on pounding probability of buildings are investigated. Comparisons of the pounding related provisions in the Taiwan Building Code and those in the Uniform Building Code (UBC) are made. The results reveal that if a reduction coefficient of 0.375 is adopted, instead of the 0.6 specified in the TBC, to consider the effect of vibration phase difference of adjacent buildings, the critical pounding risk of the TBC and that of the UBC will be similar.
