钢筋混凝土网格框架墙体非线性数值分析

摘要

采用有限元分析软件ANSYS对网格框架墙体进行了数值模拟，并结合前期试验，进行了数值结果与试验结果的比较。比较分析认为ANSYS软件能够较好地模拟墙体内力和变形发展的全过程以及裂缝的形成与发展过程，可以满足实际工程实施与科学研究的精度要求。在此研究基础上，又对前期试验中没有涉及到的其他参数进行了模拟，从而完善了影响钢筋混凝土网格框架新型墙体抗震的其他因素。%Through the previous researched results, grid frame wall are analyzed by the finite element analysis software ANSYS numerical simulation in this text. With the results of the grid frame wall tests and finite element analysis, it can be concluded that the finite element model can be used to imitate the developing process of the inner force and the deformation of the grid frame wall, as well as to describe the form and extension of the crack in the walls, which is accurate enough in engineering and scientific research. On that basis, other parameters are imitated that the test didn't involve, thereby grid frame wall is improved in anti-seismic aspects.
