摘要
随着低层砌体结构被广泛应用于新疆村镇的庭院经济,本文依据村镇建筑传统的施工工艺,将预制耐水石膏基构造柱和沙漠砂蒸压加气混凝土砌块通过砌筑的方式结合起来,提出一种新型的装配式构造柱约束沙漠砂蒸压加气混凝土砌块墙体,并对其进行低周反复荷载试验,研究其破坏特征、承载能力及滞回性能等抗震能力。试验结果表明:随着竖向压应力的增加,墙体的承载能力随之增加,延性减小。基于上述试验结果提出了地震作用下装配式构造柱约束沙漠砂蒸压加气混凝土砌块墙体的抗剪承载力计算方法,对比结果表明计算值与试验值吻合较好,可为该新型砌块村镇建筑的工程应用提供理论依据。
With the low-rise masonry structure is widely used in the courtyard economy of villages and towns in Xinjiang,according to the traditional construction technology of rural buildings,prefabricated water-resistant gypsum-based structural columns and autoclaved aerated concrete blocks in desert sand are combined by masonry,then a new autoclaved aerated concrete block wall in desert sand restrained by prefabricated structural column is proposed and were tested under low-cycle reversed loading to analyze its failure characteristics,bearing capacity,hysteretic behavior and other seismic capabilities.The test results show that with the increase of vertical compressive stress,the bearing capacity of the wall increases,and the ductility decreases;based on the test results,the calculation method for the shear strength of the autoclaved aerated concrete block wall in desert sand restrained by prefabricated structural column under earthquakes is proposed,and the calculated values are in good agreement with the experimental ones,which provides the theoretical basis for the engineering application of the village architecture of this new block.
