摘要
本文从钢筋混凝土板的内力平衡微分方程和下限定理出发,对板的设计原理进行分析,从而指出钢筋混凝土异形板采用基于有限元的内力分析却忽略其扭矩的传统设计方法所存在的问题,并在此基础上提出合理的设计建议,通过对案例进行分析,证实其合理性。本文的异形板有限元分析和设计方法可供相关工程参考。
This paper studied the fundamental methodology of RC slab design from the perspective of Lagrange's 4th order partial differentiation equation and lower bound theorem,then a problem of traditional design approach for irregular RC slab which mainly focus on deriving alternative moment fields by eliminating the twisting moment was specified. Two design cases were introduced and checked with suggested approaches that design irregular RC slab based on FEM. Methodology for irregular RC slab design stated in this paper can be used as reference for other projects.
