摘　　要：为了促进自保温砌体的推广应用和提供自保温砌体设计依据。采用伺服加载系统,通过3个无灌芯和3个灌芯砌体受压、受剪等基本力学试验,系统研究了砌体破坏特征、抗压强度、抗剪强度等砌体基本力学性能。通过对现行规范或资料提供的计算方法与试验结果进行比较,无灌芯砌体抗剪强度平均值是现行规范计算值为0.69倍,灌芯砌体的实际平均抗剪强度是无灌芯砌体的3.2倍。试验结果拟合的保温砌体本构关系可作为数字模拟计算参数设置依据。本试验数据及分析结果可供同类砌体结构设计参考。以工程应用实例证实保温节能墙体的实际隔热效果。:In order to promote the popularization and application of self-insulating masonry and provide the design basis of self-insulating masonry.The basic mechanical properties of masonry,such as failure characteristics,compressive strength and shear strength,were systematically studied by using servo loading system.By comparing the calculation method provided by the current code or data with the test results,the average shear strength of the non-core masonry is 0.69 times the calculated value of the current code,and the actual average shear strength of the core masonry is 3.2 times that of the non-core masonry.The constitutive relation of the thermal insulation masonry fitted by the test results can be used as the basis for the numerical simulation calculation parameters.This test data and analysis results can be used as reference for similar masonry structure design.The practical thermal insulation effect of thermal insulation and energy saving wall is proved by engineering application examples.
