通过对七孔空心砖砌体的轴心抗压、偏心抗压、通缝抗剪和齿缝抗剪试验,证明空心砖砌体的力学性能指标和普通粘土砖砌体基本相当,按现行《砖石结构设计规范》规定的指标进行结构计算,偏于安全。为大力推广空心砖的生产和应用,提供了应用方面的试验依据,同时为已建的空心砖建筑物提供了安全使用的技术依据,节约了结构加固费用。
Through the axial compression, eccentric compression, through-seated shear and tooth shear shear tests of seven-hole hollow brick masonry, the mechanical properties of hollow brick masonry are basically the same as ordinary clay brick masonry. The Structural Design Specification stipulates that the structural calculations are based on indicators that are biased toward safety. In order to promote the production and application of hollow bricks, it provides experimental basis for application. At the same time, it provides the technical basis for the safe use of hollow brick buildings that have been built, and saves the cost of structural reinforcement.
