现代建筑物中越来越多的采用轻钢门式刚架,门式刚架中节点设计是制约整体稳定、安全的关键环节。节点域内力传递十分复杂,是目前设计的难点和研究的热点。利用ANSYS对节点域在反复循环荷载作用下进行受力性能分析,在此基础上提出节点域腹板薄板稳定检验理论,保证腹板的受力更加均匀、合理,充分发挥材料的潜在性能,有效提高地面建筑的整体性和稳定性。
More and more light steel portal frames are used in modern buildings. The design of nodes in the portal frame is the key link that restricts overall stability and safety. Nodes in the field of internal force transfer is very complicated, is the current design difficulties and research hot spots. By using ANSYS, the stress field analysis of node area under repeated cyclic loading is carried out. On the basis of this, the theory of stability testing of web web in node area is proposed to ensure that the stress of web is more uniform and reasonable, and the potential performance of material is fully utilized. Improve the integrity and stability of ground buildings.
