Study on Mechanical Behavior of Floor Surface Based on Layered Shell Elements
To study the stress performance of the floor under seismic action,the nonlinear finite element software ABAQUS layered shell element is used to simulate and compare the test results of the shear wall,and to determine the reliability of the concrete and steel constitution and calculation parameters.The finite element analysis of the stress properties of typical concrete floors under complex stress conditions is carried out,and the applicability of the simplified calculation method to evaluate the in-plane tensile,compressive and shear bearing capacity of the floor is investigated.The analysis results show that the simplified method is consistent with the finite element calculation results when determining the bearing capacity of concrete floors under fortification intensity.The measures to strengthen the seismic performance of the floor are put forward in accordance with the damage criteria of concrete floors under seismic action in engineering.
