Finite Element Analysis of BF Section Steel EPS Foam Concrete External Wallboard
In order to study the effect of basalt fiber on the prefabricated external wallboard of section steel EPS foam concrete,the constitutive curves of EPS foam concrete with different amounts of basalt fiber were obtained through prismatic test and related literature,and the finite element analysis of the prefabricated wallboard was carried out by using the finite element software ABAQUS to explore the influence of different dosages on the me-chanical properties of EPS light aggregate concrete.The results show that when the basalt fiber content is 0.2%,the bearing capacity of the component is significantly improved.When the basalt fiber content is 0.6%,the bear-ing capacity of the component is almost not improved,and the ductility decreases.Therefore,the optimal dosage is 2%.In addition,the cold-formed thin-walled C-beam has high bond strength with EPS foam concrete,and the addition of basalt fibers does not change the failure mode of the wallboard.
