Secondary Moment Distribution of Prestressed Concrete Slab

In this paper, the multi-span continuous two-way slab is analyzed with finite element method of the secondary moment distribution characteristics. When the support beam size changes, affect secondary moment in the plate. Drawn by the existence of the beam, different size of the beam has a great influence on the board secondary moment values. Likewise, threatening the secondary moment in beam may also be affected. Suggestions in the actual engineering design, not only in the beam slab should be considered themselves times the size of the bending moment, should also be considered secondary moment of mutual influence between beam and slab.
