| Abstract: | A deflection calculation method of beams with longitudinal dentiform section was carried out from the formula of general displacements calculating.The stair bearers were considered as typical representations of longitudinal dentiform section beam,the combine action of bending moment and shear force was taken into account.The influences,which acted on beam's equivalent depth in deflection calculating caused by the change of longitudinal dentiform section and the ratio of span to depth,were comprehensively analyzed.Therefore,the simplified calculation methods of longitudinal dentiform section beam's deflection are derived,several practical conclusions are presented,and some problems to which should be paid attention are posed. |
