In order to investigate the influence of different parameters on the bearing performance of close-packed stacked two-way slabs,a multi-parameter analysis was carried out by numerical simulation of the structural distribution of the thickness of the cast-in layer,additional structural reinforcement and joint reinforcement of the close-packed stacked two-way slabs.The results show that the thickness of the cast-in layer has the greatest influence on the deflection and flexural capacity of the close-packed stacked slab,and the joint reinforcement and structural reinforcement have less influence on it,while the distribution of the upper compression reinforcement,the lower tensile reinforcement and the joist reinforcement is the same.Combined with the formula of flexural capacity and deflection of cast-in-place two-way floor slab under 4-side fixed support,the calculation model of flexural capacity and deflection of close-packed stacked two-way slab under 4-side fixed support is obtained.
