摘　　要：在对某双塔连体结构进抗震分析的基础上,对此工程的结构方案进行优化,利用结构计算程序,对多个模型进行了小震弹性分析对比。对整体模型进行了大震弹塑性静力分析。探讨了大底盘双塔弱连体结构模型的选取、结构振动特性和最终的设计措施。采用基于性能抗震设计方法,保证连体及支承连体构件在中震作用下保持弹性,滑动支座的滑动量在控制位移范围内。In this paper,a siamesed structure with two-tower is analyzed.Structure plan of the library is optimized.Based on the computation result of some structure programs,several models of structure are analyzed under minor seisms.Pushover analysis is used for integral model.Selection of structure model,vibration characteristic and the final design measures are discussed.Seismic design based on performance is proposed.Siamesed structural members and supporting members are elastic under intermediate seisms,slippage is in control.
