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.

这项分析性研究项目研究了强震期间建筑物碰撞的非线性问题。本文将考察几种具有不同刚度和冲击特性的建筑物的典型布置，包括柱与板的碰撞。将对现行规范中估计抗震接缝间隙要求的规定进行验证。将提出缓解冲击影响的补救措施。本研究得出的建议对地震区密集相邻建筑的改造具有重要的参考价值。
