Analysis of Slab and Beam’s Moment Influenced by Stiffness Ratio

Abstract:

In this paper ,taking industrial factory building , the size of 33 * 19.8 m² for example, analyzes Integral reinforced concrete floor system under the loads by Finite element analysis software ANSYS. In the calculation process, beam element is beam4, slab element is shell63, Changing the line stiffness ratio of beam and slab, main beam and secondary beam, researches of moment on the main beam and the secondary beam by means of line stiffness ratio. It is showed that , when the value of line stiffness ratio is more than 10, mid-span moment is fewer obviously with the Increasing K ; when the value of line stiffness ratio is between 2 and 5, mid-span moment is fewer, too; when the value of line stiffness ratio is shorter than 2, mid-span moment does almost not changed.
