摘要
混凝土小型空心砌块是取代粘土砖的首选材料,且高强砌块的基本力学性能有待于进一步完善。因此,本文通过70个全部灌芯高强砌块标准件的抗压和抗剪试验,了解高强砌块灌芯砌体的破坏形态及破坏机理,同时根据试验数据回归得出高强砌块灌芯砌体的抗压强度、抗剪强度的计算公式,验证了GB50003《砌体结构设计规范》(报批稿)公式,为高强混凝土空心砌块在中高层建筑中的推广、应用提供依据。
From the experimental results obtained with70pieces of standard specimens built of entirely grouted high strength concrete small hollow blocks,their failure pattern and mechanism,and a set of compression and shear strength formulae are established through theoretical analysis of experimental data.Primary data are obtained for the application of high strength concrete small hollow blocks to medium and high structures.
