摘要
非线性有限单元法是目前非杆件体系结构配筋设计最具有发展前途的方法,也是现行水工混凝土结构设计规范列出的配筋方法。为在水利工程中推广非线性有限单元法配筋,自主研发了一套非线性有限单元法配筋系统。结合工程实例,运用该系统对某泄洪深孔建模计算,先用应力图形法求得初步配筋结果,再用非线性有限单元法计算裂缝分布及宽度,校核配筋方案。该方法简单易用,具有较大的工程应用价值。
Non-linear FEM is the most promising method for the design of non-pole structure reinforcement, and it is the one that listed by current standard of hydraulic concrete structure. To promote non-linear FEM in hydraulic engineering projects, this paper developed a system of reinforcement based on non-linear finite element analysis. Combined with project case, the system was used to calculate a deep hole modeling of flood discharge. Firstly,this paper obtained the initial reinforcement results by using stress graphics method,and than it calculated the distribution and width of fractures by non-linear FEM, which could check the final scheme. This method was simple and easy to use and has great application value.
