箱梁牛腿横向应力分布及有效计算宽度有限元数值分析研究

Study on the Distribution Regularity of Transverse Stress and the Effective Calculating Width of Corbel in Box Beam by Finite Element Method

采用有限元数值分析方法,针对牛腿的不同情况,分析牛腿沿横向和竖向的应力分布规律,探讨横桥向支座宽度以及水平力对牛腿有效计算宽度的影响。

The distribution regularities of stress in transversal and vertical direction of corbels in different condition is analysed by finite element method. The width of support abutment and horizontal force's effect on the effective calculating width is also discussed.
