针对复杂非杆系结构配筋设计难度较大的问题,以某混凝土拱坝孔口为例,运用ABAQUS软件分析了最不利工况条件下的孔口应力。依据拉应力图形法原理,采用C#程序语言编制了配筋程序,实现了截面的剖切、应力的平面投影、拉应力面积的计算以及配筋截面面积计算等功能。研究结果可为非杆系结构工程配筋设计与施工提供参考。 Aiming at the difficult design of complex non-bar structure reinforcement design, taking the orifice of a concrete arch dam as an example, the stress of the orifice under the most unfavorable working condition was analyzed by ABAQUS software. According to the principle of tensile stress graph method, the reinforcement program was programmed by C # programming language, which realized the functions of sectioning, plane projection of stress, calculation of tensile stress area and calculation of reinforcement section area. The research results can provide references for the design and construction of non-structural steel bars.
