摘要
采用显式积分法探讨了砖石古塔的地震破坏机制.应用动力弹塑性分析法表征并求解砖砌体结构破坏的非线性问题,得到古塔在地震作用下产生变形、开裂、压溃等结果的动态过程和破坏形态.结果表明,显式积分法适用于模拟砖石古塔的震损演化过程.
Based on explicit dynamic principle,a new approach on investigation seismic damage mechanism of ancient masonry pagodas has been probed in this paper.And how to present and solve the nonlinearity on seismic damage of masonry structure in the dynamic elastic-plastic analysis have been discussed.The simulating results of the dynamic response and failure pattern(such as deformation,cracking and crushing)of an ancient masonry pagoda show that explicit integral method is applicable to simulate the evolution of the seismic damage of a masonry pagodas.
