摘要
天津市某商业框架采用48个屈曲约束支撑进行消能减震设计,分别采用SATWE和Perform 3D软件进行小震和中、大震分析。小震分析表明,减震结构层间位移角及框架配筋显著减小,实现“小震不坏”的目标要求。中、大震作用下,屈曲约束支撑进入屈服耗能状态,同时提供附加阻尼,能够保护主体结构抗震性能。大震分析表明,结构位移角及屈服机制满足要求,达到“大震不倒”的目标要求。
In a commercial frame in Tianjin, 48 buckling restrained braces were used for energy dissipation and shock absorption design, and SATWE and Perform 3 D software were used for small earthquake, medium earthquake and large earthquake analysis respectively. The analysis of small earthquake shows that the displacement angle between floors and the reinforcement of the frame are significantly reduced, and the goal of “not bad in small earthquake” is achieved. Under moderate and large earthquakes, buckling restrained braces enter the yield energy dissipation state and provide additional damping, which can protect the seismic performance of the main structure. The analysis of large earthquake shows that the displacement angle and yield mechanism of the structure meet the requirements and reach the target of “no collapse in large earthquake”.
