摘要
发明一套新型的混凝土复合保温砌块,提出一种采用异形复合保温砌块组砌圈梁、构造柱模板的构造方式,有效解决了现有自保温砌块砌体结构中圈梁、构造柱的冷桥问题。通过对四组分别采用新型构造方式砌筑及按照传统方式砌筑的足尺混凝土复合保温砌体墙体进行水平低周反复荷载试验,对比分析两种墙体的破坏过程、滞回特性、延性、耗能能力以及刚度退化等抗震性能指标。试验结果表明:新型混凝土复合保温砌块承重墙具有与传统方式砌筑墙体相同的抗震性能。
A new set of compound masonry blocks that feature heat preservation has been designed and a new wall construction method has been proposed. Walls applied with this method have a heat-preserving layer on the outside of their ring beams and construction columns. Eight full-size concrete compound heat-preserving masonry walls were tested under low cyclic horizontal loadings. The earthquake resistant performance indicators of the wall, such as damage process, hysteresis features, ductility, energy dissipation and rigidity deterioration were studied. According to the experiments, the wails constructed by the new method are similar to the traditional walls in terms of failure mode, hysteresis features, ductility, energy dissipation and rigidity deterioration.
