摘　　要： 针对深圳市急救血液信息三中心公共卫生项目存在扭转不规则、凹凸不规则、楼板不连续、尺寸突变及其他不规则超限项,对两侧塔楼各自独立抗震与两侧塔楼设置弱连接部位整体抗震进行包络,并对其进行多遇地震、设防地震及罕遇地震作用下抗震性能化设计。计算结果表明:对结构之间的弱连接部位采取楼板加宽、框架梁及框架柱设置型钢等抗震加强措施,构件可满足预定的性能目标要求,结构整体趋于稳定。 In view of the existence of torsional irregularities,irregularities,discontinuous floor slabs,abrupt size changes,and other irregular over-limits in the public health project of Shenzhen Emergency Blood Information Center III,envelope the independent earthquake resistance of the towers on both sides and the overall earthquake resistance of the weak connection parts of the towers on both sides,and design the seismic performance under the action of multiple earthquakes,fortified earthquakes and rare earthquakes.The calculation results show that by adopting seismic strengthening measures such as floor widening,frame beams and frame columns with section steel for weak connection points between structures,the components can meet the predetermined performance target requirements,and the overall structure tends to be stable.
