【摘要】

：

日本东京工业大学一座11层钢骨混凝土教学楼建筑于2009至2010年间进行抗震加固.加固时在结构纵向采用了一种新型摇摆墙-框架结构体系,而在横向则采用增设传统钢筋混凝土抗震墙的方法进行加固.在2011年9.0级的东日本大地震中,该建筑遭受到中等程度的地震地面运动作用.震后观察到的结构震损表明,摇摆墙在控制结构损伤方面较传统抗震墙更为优越.此外,建筑内部隔墙的损伤成为该建筑在这次地震中的主要损伤形式

基于钢管混凝土结构的自隔震技术

通过降低结构底层刚度,以延长结构自振周期,达到结构隔震效果.此技术由于未采用任何外设装置,因此称为结构的自隔震技术.工程应用上,结构底层采用钢管混凝土柱,可以利用钢管混凝土刚度可调的性质,提出结构柱高径比取值区间.与普通钢筋混凝土相比,钢管混凝土具有高强度、高延性等特点,高径比在此区间内的钢管混凝土柱既能使结构柔度达到隔震要求,同时又使结构满足整体稳定.为使结构在罕遇特大震下不致倾覆,建议在刚度较

预应力CFRP加固混凝土梁的预应力体系研究现状

预应力CFRP(含外贴片材与内嵌线材)加固混凝土梁是一种新型的加固方法.近年来,国内外研究人员对预应力CFRP加固混凝土梁进行了很多富有成果的试验和理论研究,但是对可用于加固实际工程的CFRP预应力体系的研究尚不成熟.预应力CFRP加固混凝土梁预应力张拉体系研究方面主要存在实际应用中的可操作性不强,体系加固混凝土构件的有效性等研究不足；预应力CFRP加固混凝土梁预应力锚固体系研究方面主要存在锚具的
