Realization of Concrete Temperature Stress Field Simulation Analysis on ANSYS Software

探讨了ANSYS软件模拟混凝土瞬态温度场理论上的可行性,研究了施工期及运行期温度场、温度应力场仿真计算的主要问题及相应的关键技术,基于通用有限元软件ANSYS平台,设计了仿真分析流程图,通过各模块的交互运用,利用参数设计语言(APDL)以及多种内部函数,编制了宏命令以控制ANSYS程序,成功实现了仿真分析过程从建模、求解及后处理的参数化,提高了利用ANSYS软件解决工程实际问题的效率.

The theoretical practicability of simulating the concrete temperature field on software ANSYS is discussed. The principal problems and the corresponding key technologies of simulating the concrete temperature field and temperature stress field are studied. Based on the general service flatbase of the finite element software ANSYS, a flow chart of simulation analysis is designed. By running some modules interactively,and using APDL and built-in functions of the software ANSYS,the control program is developed to control software ANSYS,thus it is possible to describe the analysis process, which is from modeling and numerical calculation to post-treatment by parameter, greatly increasing the efficiency of solving the engineering problems by the large universal software ANSYS.
