中建滨湖设计总部BRB-装配式铰接框架设计

Design of BRB-assembled articulated frame in China Construction Binhu Design Headquarters

中建滨湖设计总部项目提出了一种BRB-装配式铰接框架,其特点为BRB所在跨梁柱铰接,并与其他跨普通框架共同形成抗侧力体系。为了研究BRB-装配式铰接框架的受力性能,利用MIDAS Gen软件,采用静力弹塑性(Pushover)分析方法,对比了单榀框架、BRB-装配式框架和BRB-装配式铰接框架的逐级加载全过程受力特点。分析结果表明,BRB-装配式铰接框架的刚度、屈服承载力和极限承载力介于单榀框架和BRB-装配式框架之间,延性好,耗能强,可广泛应用于工程实际。

The China Construction Binhu Design Headquarters project proposed a BRB-assembled articulated frame,which was characterized by articulated beams and columns on the span where BRB was located,to form a lateral force resistance system together with other common span frames.In order to study the mechanical performance of BRB-fabricated articulated frame,MIDAS Gen software and static elastoplastic analysis method were used to compare the mechanical characteristics of the single piece of frame,BRB-assembled frame and BRB-assembled articulated frame in the whole process of step by step loading.The analysis results show that the stiffness,yield capacity and ultimate bearing capacity of the BRB-assembled articulated frame are between the single piece of frame and the BRB-assembled frame,with good ductility and high energy consumption,and can be widely used in engineering practice。
