Abstract
Through some engineering example, the finite element software SAP2000N is used to make a finite element analysis on the prestressed concrete slab, which is made of concrete with grade of C40, low relaxation PC strand wile with tensile strength standard value of 1860N/mm2and nonprestressed reinforcements with grade of HRB335. By doing this, the author systematically introduced the material selection, prestressing technique and linear, load values and internal force calculation, distribution of prestressed tendons and nonprestressed reinforcement, the design process of crack and deformation of cast-in-site prestressed concrete two-way slab.
