Prefabricated molded steel and hollow concrete combined plate for bending resistance numerical simulation of bearing capacity
In this paper,a new type of prefabricated compacted steel-hollow concrete composite plate is pro-posed,and finite element models with different design parameters are established by using ABAQUS soft-ware.The influence of the thickness of the combined plate,the thickness of molded steel,and the radius of hollow on the bending capacity of the combined plate was analyzed.The results show that under the same thickness,the flexural bearing capacity of the prefabricated molded steel-hollow concrete composite plate is increased by 15.4%and the weight of the combined plate is reduced by 37.0%.The flexural capacity of com-bined plate using molded steel is 14.7%higher than that using molded steel plate.The thickness of the com-bined plate is increased from 120 mm to 160 mm,and the ultimate bearing capacity is increased by 46.2%.The thickness of molded steel is increased from 0.6 mm to 1.0 mm,and the ultimate bearing capacity is in-creased by 54.7%.The influence of concrete hollow radius on flexural capacity is small,and the flexural ca-pacity decreases with the increase of hollow radius.
