防屈曲支撑是一种兼具承载和耗能的抗侧力构件,相比于普通支撑,具有耗能稳定且延性好的优点,在模块化结构中,防屈曲支撑可作为模块内单元,通过带防屈曲支撑模块单元装配的方式形成防屈曲支撑钢框架模块结构。提出了防屈曲支撑钢框架模块装配结构体系、防屈曲支撑在模块化结构中的设计要求以及结构体系设计方法,并以20层住宅楼为例进行设计,包括典型高层住宅及其模块划分及结构在小震和大震下的抗震性能进行分析。反应谱分析结果表明:设计的模块化结构能满足规范对结构的各项要求。对布置了普通支撑与等刚度防屈曲支撑的模块化结构进行了静力弹塑性分析,静力弹塑性分析结果表明:在8度罕遇地震下,普通支撑结构部分支撑发生屈曲破环,布置等刚度的防屈曲支撑框架只有第二层出现塑性铰,结构能够经受8度罕遇地震的考验,防屈曲框架结构的初始刚度与普通框架结构一致,但极限承载力明显大于普通支撑框架结构;防屈曲支撑较普通支撑能显著提高模块化结构的承载力,且能率先屈服发挥耗能作用,保护主体结构安全,符合双重抗侧力体系的原则,防屈曲支撑钢框架模块装配式结构体系具有优越的抗震性能,有很好的应用前景。
Buckling restrained brace (BRB) is a kind of anti-side force member with both load-bearing and energy consumption. Compared with the ordinary brace, it has the advantages of stable energy consumption and good ductility. In a modular structure, BRB can be used as a unit in the module. The module unit with BRB is assembled to form the BRB steel frame module structure. This article introduces the assembly structure system of BRB steel frame modules, including typical high-rise residential buildings and their module division, BRB steel frame module assembly structure and structural system design method, the design requirements of BRB in modular structure, and the 20-story residential building was designed as an example to analyze the seismic performance of the structure under frequent and rare earthquakes. The results of response spectrum analysis show that the designed modular structure can meet the requirements of the code for the structure. A static elasto-plastic analysis of the modular structure with ordinary brace and equal-rigidity BRB was carried out. The results of the static elasto-plastic analysis show that some supports of the ordinary brace structure buckled and broke under the rare earthquake of 8 degrees. In the BRB frame with equal stiffness BRB, only the second layer has plastic hinges, and the structure can withstand the test of 8 degree rare earthquake. The initial stiffness of the BRB frame structure is the same as that of an ordinary brace frame structure, but the ultimate bearing capacity is significantly greater than that of the ordinary brace frame structure. The BRB can significantly improve the bearing capacity of the modular structure compared with the ordinary brace, and can first yield to play an energy dissipation role, which protects the safety of the main structure and comply with the principle of the dual lateral force system. The BRB steel frame modular assembly structure system has superior seismic performance and has a good application prospect.
