Nonlinear seismic response analysis of concrete perforated brick masonry building

摘要

In order to grasp the seismic performance of the concrete perforated brick masonry building, nonlinear dynamic analysis is used for seismic response analysis of multi-storey building. In the degradation of trainer restoring force model, it is proposed that the yield moment of the inflection point is calculated by linear interpolation, the unloading time of inflection point is calculated by the precise non-iterative, which approach to improve the accuracy and efficiency of nonlinear analysis. Example shows: concrete perforated brick masonry structure in the 7-degree multi-zone can be widely used.
