摘要

摘要: 重要建筑物由于特殊的形体要求,结构布置常常不规则且抗震设防标准高。按常规方法进行设计遇到很大困难。通过两个途径改善了建筑物的抗震性能:一是针对结构平面布置的不规则,调整局部构件的截面抗弯刚度,实现结构整体刚度内在的规则分布;二是采用被动耗能减震技术,通过设置油阻尼器,为结构提供附加阻尼。

Abstract: For critical buildings, due to the special shape demands, the structural layouts often become irregular. On the other hand, because of the importance of their function, the seismic design criterion of these buildings is higher than normal ones. The designer of structure usually encounters difficulty and challenge in the seismic design. Two approaches to improve the seismic performance of buildings were presented: One is to reallocate the bending stiffness of the local structural members in order to make the distribution of structural stiffness uniform inherently though the appearance is irregular. The other is to add some oil dampers to buildings, which may provide additional damping for structures. The analysis results indicated that the structural seismic performance could be obviously enhanced due to adoption of above approaches, and the sections of structural members ( column, beam) could be reduced, and then to get better cost performance.
