Abstract:
The flexural rigidity of prestressed concrete two-way composite slab was analyzed. Based on the theory of elastic thin plates, according to the orthotropic plate's perpendicularity, the corresponding calculation formulas of rectangular unidirectional prestressed slab simply supported on four sides were deduced. Moreover, with the program written by authors, the coefficients of two-way composite slab under border simply supported on four sides were obtained, authors made a form correspondence to the composition slab. Thus, this established a stable condition for the further appliance of such composition slab. Comparing with the elastic coefficient of cast-in-site two-way slab simply supported on four sides, it shows that in the design of prestressed two-way composite slab, prefabricated components along step short should be fixed up, which can make full use of its advantages of saving steel products.
