Analysis of the Secondary-direction Moment and Reinforcement for One-way Slab under Line Load
摘要
Abstract
One-way slab subjected to the line load may result in a big bending moment in the secondary direction.The secondary-direction moment is easily underestimated so that a structural failure might occur.In this paper,the moment in the secondary direction for one-way slab under line load is analyzed by elastic theory and the ANSYS Code,and the corresponding reinforcement is calculated.The results show that the moment in the secondary direction has the same order of magnitude with the moment in the primary direction.The calculation method of the moment in the secondary direction of one-way slab is presented.Two feasible design suggestions are proposed.One is adding the short reinforcements in the secondary direction at the bottom of slab based on the distributing reinforcements,the other is to add a certain width of cushion under the line load.关键词
