合肥市长临河科创小镇18号楼抗震设计

Seismic design of No. 18 tower in Changlinhe Science and Innovation Town of Hefei

合肥市长临河科创小镇18号楼为大跨度空间结构且端部存在大悬挑,并存在扭转不规则、凹凸不规则、尺寸突变的不规则情况。根据设计依据及场地特征,针对不规则情况进行多遇地震作用下弹性时程分析和罕遇地震作用下动力弹塑性时程分析,并进行了舒适度验算,最后总结并提出了该不规则结构抗震加强措施。

The No.18 tower in Changlinhe Science and Innovation Town of Hefei has a large-span spatial structure with a large cantilever at the end,and there are irregularities such as torsion irregularities,irregular bumps and irregularities sudden changes in size.Based on the design basis and site characteristics,elastic time history analysis under frequent earthquakes and dynamic elastoplastic time history analysis under rare earthquakes for irregular situations,and comfort check calculation were conducted.Finally,the seismic strengthening measures for the irregular structure were summarized and put forward.
