| Abstract: | Based on the Levy＇s solution of elastic thin plate, this paper analyzes the deflection of bearing beam affects the moment of plate in continuous plate beam structures, and obtains the calculation of support moment and mid-span moment of plate in view of the beam deformation. Through a calculation example, the effects of various factors on the deflection of bearing beam and the support moment and mid-span moment of plate are analyzed. In the last, some improved methods are put forward for the design of continuous plate. |
