分析本项目建筑的不规则内容,并且运用正确的抗震设计概念,针对该工程特点及结构设计难点,经过全面、可靠的计算分析,提出相应的抗震加强措施.主要包括关键剪力墙全高设置约束边缘构件,满足正截面抗弯承载力中震不屈服、斜截面抗剪承载力中震弹性的性能目标,对关键处楼板进行应力分析,对楼板分析中应力较大的部位加大配筋、连接板截面加大与配筋加强,以及通过改变建筑布局增设连接板等措施.结果表明,采取上述加强措施,该结构设计能实现拟定的抗震性能目标,结构安全可靠.
Analysis and Discussion on the Design of a Complex High rise Structure
Analyze the irregular content of the building in this project,and apply the correct seismic design concept.Based on the characteris-tics and structural design difficulties of the project,through comprehensive and reliable calculation and analysis,propose corresponding seis-mic strengthening measures,which mainly includes setting constraint edge components at the full height of key shear walls,meeting the per-formance goals of normal section bending bearing capacity without yielding during earthquakes,oblique section shear bearing capacity with e-lasticity during earthquakes,floor stress analysis,and strengthening measures such as adding connecting plates by changing the building lay-out.The results indicate that the structural design can achieve the proposed seismic performance goals,and the structure is safe and reliable.
