【摘要】 汶川地震中大量教学楼由于抗震能力不足而倒塌,造成了巨大的灾难和损失,为此,对学校建筑进行抗震加固异常迫切。屈曲约束耗能支撑在受拉和受压两种状态下都能达到屈服,克服了普通支撑受压屈曲的问题,是一种集抗侧力和耗能为一体的耗能减震构件。结合学校加固工程特点以及屈曲约束耗能支撑的性能,提出了屈曲约束耗能支撑在教学楼加固中的设计、施工方法。通过弹性以及弹塑性分析方法研究了采用屈曲约束支撑加固后教学楼的抗震性能。更多还原

【Abstract】 Many classroom buildings were destroyed and millions of students lost their lives in Wenchuan Earthquake.So seismic restrofitting of classroom buildings is important for many schools in China.And some schools have been rehabilitated in the last years.Buckling-restrained-brace(BRB) is a kind of prospective energy dissipation component.As a brace,it’s also a lateral force resistant member.Based on the characteristics of classroom building seimic retrofitting and BRB,the appliction of buckling-restrained-braces in the classroom builing seimic retrofitting is presented.By elastic and elasto-plastic analysis,the seismic behavior of the retrofitted.更多还原
