Jianzhu Gangjiegou Jinzhan, 2008 "512"汶川大地震造成了巨大的人员伤亡和经济损失。其中,学校和医院等公共建筑的倒塌更是引起了广泛关注。本文概述了这次地震中学校和医院建筑的震害情况,然后介绍了钢结构的抗震性能、历史震害特征以及可用于改进钢结构抗震性能的措施,并对现行《建筑抗震设计规范》（GB50011-2001）中关于"大震不倒验算"的条文提出了修改建议。最后,建议应推广钢结构在地震区的应用,尤其是学校和医院等公共建筑应采用钢结构。

Jianzhu Gangjiegou Jinzhan为提高屈曲约束支撑（buckling-restrained brace，BRB）在小变形阶段的消能性能，将金属消能器与国产Q355钢芯材的BRB并联，构成新型多级屈服复合减震（简称SD-BRB）构件。在试件小变形阶段，金属消能器率先屈服消能；当试件变形增大时，BRB进入屈服阶段，从而实现两阶段屈服设计目标。文中设计了2根试件，用以通过试验对比复合减震构件与常规BRB构件的抗震性能。试验结果表明：与国产Q355钢为芯材的BRB并联的构件其抗震性能满足建筑抗震设计规范的要求。相比传统BRB ...
