[摘要] 使用防屈曲支撐對(duì)一棟鋼筋混凝土框架-剪力墻結(jié)構(gòu)進(jìn)行了消能減震設(shè)計(jì)，提高了抗震設(shè)防目標(biāo)。介紹了經(jīng)過多道優(yōu)化設(shè)計(jì)的減震方案，并用等效線性法對(duì)此進(jìn)行了結(jié)構(gòu)計(jì)算，使用SAP2000N結(jié)構(gòu)非線性有限元軟件進(jìn)行了時(shí)程分析。該工程所使用的防屈曲支撐、預(yù)埋件焊點(diǎn)經(jīng)過了結(jié)構(gòu)試驗(yàn)檢測(cè)，設(shè)置防屈曲支撐的混凝土框架梁柱節(jié)點(diǎn)也經(jīng)過了類似的結(jié)構(gòu)試驗(yàn)考核。研究表明防屈曲支撐消能減震技術(shù)能與傳統(tǒng)混凝土結(jié)構(gòu)體系有機(jī)結(jié)合，成為提高結(jié)構(gòu)抗震性能、改進(jìn)結(jié)構(gòu)性態(tài)的一種有效的技術(shù)選擇。

Abstract: With seisnuc reduction technology of a kind of BRB products,a concrete frame-wall structure is design and constructed, and the seismic performance target is enhanced. The optimized seismic reduction design is introduced, and the structural responses are calculated via the equivalent linear method. Some nonlinear time history analyses are performed with the program SAP2000N. The BRB products and the welded joint within the steel-embedded parts used in this building were tested beforehand, and the concrete beam-column joints were also tested in some parallel testing projects. This paper shows that the seisnuc reduction and energy dissipation technology involved in traditional concrete structures has become an effectively technical choice in improving buildings' seismic performance.
Keywords: buckling-restrained brace; seismic reduction design; concrete structure; frame-wall structures
