轻质混凝土砌块砌体受压性能试验研究
|
摘要
对轻质混凝土小型空心砌块砌体进行了抗压性能试验,主要研究不同砂浆强度等级对其抗压性能的影响,分析了砌体的破坏特征、抗压强度和应力与应变之间的关系。研究结果表明:轻质混凝土小型空心砌块砌体的抗压性能和普通混凝土砌块砌体的抗压性能基本相似,极限破坏状态为砌体被贯通裂缝分隔成小立柱后破坏。通过对试验数据的整理分析,给出了砌块砌体抗压强度平均值的计算公式和上升阶段的应力-应变关系式。
An experimental study on the compression behavior of lightweight concrete small hollow block masonry is presented,considering the different grades of mortar strength effect on the compressive properties.The failure characteristics,the relationship between stress and strain and compressive strength of masonry are analyzed.The results show that the compression properties of lightweight concrete small hollow block masonry is similar to the ordinary concrete hollow block masonry,which was destroyed after the main crack forms and penetrates the specimen.Through the analysis of test data,the calculation formula of average compressive strength of the block masonry and the stress-strain relationships at the rise stage of the block masonry are suggested.
