EXPERIMENTAL AND NUMERICAL STUDY ON FLEXURAL BEHAVIOR OF THREE-LAYER REINFORCED COMPOSITE PLATES
In order to study the influence of the thickness of the composite layer and the middle layer of steel bars on the flexural performance of three-layer reinforced composite slabs,the finite element software ABAQUS is used to conduct numerical modeling based on the actual engineering project.Two groups of six finite element models are designed,and the bearing capacity and mid-span deflection of the models are compared and analyzed.The results show that the bearing capacity of three-layer reinforced composite slabs is positively correlated with the thickness of the composite layer,and the influence of the composite layer on the stiffness of the specimen reaches the maximum in the early stage of the third stage;the bearing capacity of the composite slabs is increased by about 20%～25%by the middle layer of steel bars,and the specimen appears an obvious transition stage in the stiffness decline process.The relevant laws may provide the reference for the research of three-layer reinforced composite slabs.
