摘　　要：以弹性薄板的Levy解答为基础,分析了连续板梁结构中支撑梁挠曲变形对板弯矩的影响,求得考虑梁变形时的板支座弯矩及跨中弯矩的计算式;通过对一实例的计算,分析各因素对支撑梁挠度及板支座弯矩及跨中弯矩的影响程度;最后,针对连续板的设计提出一些改进方法。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.
