Design Analysis of Unbonded Prestressed Concrete Two-way Slab Jiasheng Liu School of Energy and Civil Engineering, Harbin University of Commerce, Harbin， Heilongjiang, 150028，China heaven217@sohu.com Key words: unbonded prestressed concrete; two-way slab 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/mm2 and nonprestressed reinforcements with grade of HRB335.
The design analysis will provide reference for other similar engineering.
It is believed to be significant to provide reliable data support and theoretical basis for the similar the engineering designs and constructions.
According to the engineering experience, (1) the degree of prestressing of the cast-in-site prestressed concrete slab should be at 0.75.
