【摘要】 利用有限元软件ANSYS对一含有一端支撑在柱上另一端支撑在梁上的框架结构进行了拟静力数值分析。分析模拟得出了该框架梁的最不利截面位置,以及梁柱破坏一般规律。分析结果表明:危险截面发生在梁柱节点的梁端,与之对应的主次梁节点偏于安全;板对提高梁的承载力有很大的贡献,特别是对梁柱节点作用较大,其中主次梁节点处板面钢筋及梁柱节点处板底钢筋对提高梁的抗弯能力效果加明显。更多还原

【Abstract】 Using finite element software ANSYS to do quasi-static numerical analysis for frame beam which supportted both in beam and columns.Analysis of simulation comes to a dangerous section of the frame beam position,and comes to the general rules of beam damage.The results showed that:dangerous section in columns end,and the end of the main and secondary girder are more safer;Board has a great contribution to improve the bearing capacity,especially for Beam-column nodes,at the same time the steel of plate surface which in beam and plate bottom which in columns have a great contribution to improve the capacity of the beam bending.更多还原
