［摘要］中建濱湖設(shè)計(jì)總部項(xiàng)目提出了一種BRB-裝配式鉸接框架，其特點(diǎn)為BRB所在跨梁柱鉸接，并與其他跨普通框架共同形成抗側(cè)力體系。為了研究BRB-裝配式鉸接框架的受力性能，利用MIDAS Gen軟件，采用靜力彈塑性（Pushover）分析方法，對(duì)比了單榀框架、BRB-裝配式框架和BRB-裝配式鉸接框架的逐級(jí)加載全過(guò)程受力特點(diǎn)。分析結(jié)果表明，BRB-裝配式鉸接框架的剛度、屈服承載力和極限承載力介于單榀框架和BRB-裝配式框架之間，延性好，耗能強(qiáng)，可廣泛應(yīng)用于工程實(shí)際。

Abstract: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.

Keywords:BRB-assembled articulated frame; static elastoplastic analysis; ultimate bearing capacity; ductility
