摘要
摘 要
    免拆模保温承重墙体系是一种新型的保温节能建筑结构体系。本文通过对 4
    个高宽比为 1.2 和 2 个高宽比为 0.6 的试件在低周反复荷载作用下的试验研究和
    理论分析,并结合已有研究成果,对配筋墙片单元平面组合墙体在采用不同连接
    形式和具有不同高宽比时的承载力、刚度及衰减过程、变形性能、耗能能力、破
    坏特征等方面进行了研究。试验分析表明,采用暗柱连接和素混凝土缝槽连接的
    方式是可靠的,连接后的墙体能够良好的工作;高宽比的改变对试件的抗震性能
    影响较大:当高宽比大时,高宽比的变化使试件变形能力明显减小,高宽比小时,
    高宽比的变化对墙体承载力影响明显。最后,提出了对此类墙体设计计算的建议
    公式,经计算值与实测值的比较,符合较好。
The structural system of concrete bearing wall combined with insulating forms as
    heat-proof layers is a new type energy saving structural system of the bearing wall. In
    this thesis, the experimental investigation and theoretical analysis of the four
    specimens of aspect ratio for 1.2 and the two specimens of aspect ratio for 0.6 under
    the cyclic loading, combined with anciently production, are carried out to study on
    load carrying capacity, stiffness, deformation ability, energy consuming capacity and
    failure characters of walls with different type of attachment and aspect ratio. It is
    shown that it is reliable to adopt the connective mode of the embedded column or the
    slit plain concrete . Transformation of aspect ratio has major affect on seismic
    behavior of specimens. When aspect ratio is large ,decrease of deformation ability of
    specimens is obviours with shift of aspect ratio .When aspect ratio is low ,increase of
    load carrying capacity of specimens is obviours with aspect ratio. Based on the test
    results and analytical research, some formulas are proposed for estimating the bearing
    capacity and the calculation results agree well with the measured.
