To study the mechanical properties of the steel-plastic bidirectional grille.Through mechanical properties analysis and tensile,deflection and creep test,to influence the mechanical properties of grille,the change curve of load and time,creep at different temperatures.The results show that,the steel-plastic bidirectional grille has a good resistance to structural deformation,node distortion damage and deformation settlement ability.The tensile deformation of steel and plastic two-way grille includes three stages:low load large deformation stage,high load small deformation stage,and fracture stage.The temperature under different environmental conditions affects the grid creep performance.The deflection deformation of steel-plastic bidirectional grille cast-in-place concrete bidirectional slab is divided into three stages,linear elastic stage,nonlinear stage and yield stage.
