甘肃兰州某医院项目,其11层主楼采用防屈曲支撑-钢筋混凝土框架减震结构,通过与传统抗震设计采用的框架-抗震墙结构相比较,对两种结构的自重、构件截面、动力特性、层间剪力、结构侧移、抗震性能等进行对比与分析;结果表明,采用减震设计后,结构构件截面减小、结构自重减轻、地震作用降低、结构抗震性能目标提高。同时,建议性地提出一般减震项目的结构设计流程以及规范对防屈曲支撑性能要求的一些计算方法。
Gansu Lanzhou hospital project, the 11-storey main building using buckling support - reinforced concrete frame damping structure, compared with the traditional seismic design of the framework - the seismic wall structure, the two structures of self-weight, cross-sectional structure, dynamic characteristics, The results show that the cross-section of the structural members is reduced, the weight of the structural members is reduced, the seismic action is reduced and the seismic performance of the structure is improved. At the same time, it is advisable to put forward the structural design flow of the general shock absorption project and some calculation methods to regulate the performance requirements of the buckling prevention.
