ALC板构砌体抗压性能试验OA北大核心

In order to study the compressive performance and failure morphology of ALC slab masonry,and com-pare it with ALC block masonry,a compressive performance test is carried out on 6 ALC slab masonry specimens and 3 ALC block masonry specimens,and the axial compressive strength,deformation performance,failure process,and failure phenomena of each specimen are obtained.The differences between the stress-strain curve,elastic modulus and Poisson's ratio of ALC slab masonry and ALC block masonry are compared and analyzed,and the test results are verified by the finite element simulation analysis method.The ALC slab masonry can make the stress distribution in the wall more uniform,which not only improves the compressive bearing capacity of the wall,but also enhances the ductility of the wall.And through the analysis of the test data,combined with the current code,the proposed calculation formula for the compressive strength of ALC slab masonry is given,which provides a reference for the calculation and research of the compressive bearing capacity of ALC slab masonry.And the fi-nite element simulation analysis results are in good agreement with the test results,which provides a theoretical basis for the application of slab masonry in practical engineering.The compressive strength and crack resistance of ALC slab masonry are better than those of ALC block masonry in the compressive performance test.
