Mutual Pounding of Structures During Earthquakes

本分析研究项目探讨强震时建筑物碰撞的非线性问题。将研究几种具有不同刚度和冲击特性的建筑物的代表性布置，包括柱对板的冲击。现行规范中关于估计地震节点间隙要求的规定将得到验证。将提出减轻冲击影响的补救措施。本研究提出的建议对震区内相邻建筑的加固具有重要的参考价值。

This analytical research project investigates the nonlinear problems of building collision during strong-motion earthquakes. Several representative arrangements of buildings with different stiffness and impactive characteristics including column to slab pounding will be examined. Current code provisions for estimating the requirements for gaps at seismic joints will be verified. Remedies to mitigate the pounding effects will be suggested. The recommendations drawn from this study will be of great value for retrofitting of closely spaced adjacent buildings in seismic areas.
