摘要
成都市天府软件园三期工程由多幢平面凹凸不规则、扭转不规则和沿竖向刚度不均匀的建筑组成,其中B,C座从层11至屋面层采用钢桁架连廊连成一体,成为连体结构,且底层设置2层连通的架空层,层2楼板开洞面积为该层面积的47%。为研究其抗震性能,进行缩尺(1/30)模型的振动台试验,在试验结果的基础上,对该建筑的整体和局部结构的抗震性能进行评价。试验结果表明,通过采取抗震加强措施及合理设计,结构能够满足抗震性能目标。
Phase Ⅲ project of Tianfu Software Park in Chengdu consists of several buildings with plan irregularity, torsion irregularity and vertical stiffness irregularity, in which B and C buildings are linked by corridors of steel truss from the 11 th story to the top story. Stilt floor is built in the first and second story, while the opening area in the second story accounts for 47% of the whole floor area. To investigate its seismic performance, shake table tests on a 1/30 scale structural model was carried out, and the global and local seismic performance of the buildings are evaluated based on the testing results. The test results show that the structure can satisfy the present performance objectives through rational design and seismic measures.
