| 文章以合肥某框架剪力墙结构为例，针对该平面V型抗侧力构件斜交、竖向带斜柱的不规则高层建筑结构，开展对结构整体及斜柱的抗震性能研究。在多遇地震下进行结构整体和分块弹性计算，并分析斜柱及与其相连构件内力；在罕遇地震下分别采用静力弹塑性和动力弹塑性两种不同的力学模型进行对比计算，分析结构与斜柱在大震下的性能状态。文中对斜柱节点及与其相连处楼板进行了在不同地震水准下的应力分析。结果表明：整体结构能够满足抗震性能目标要求，且该斜柱构件在地震作用中无损坏，可满足工程使用安全的要求。 |
| 英文摘要: |
| The article takes a frame-shear wall structure in Hefei as an example, focusing on an irregular high-rise building characterized by diagonally intersecting V-shaped lateral force-resisting components and vertical inclined columns. It conducts a study on the seismic performance of the overall structure and the inclined columns. Under frequent earthquakes, elastic calculations are performed for both the entire structure and segmented components, with analysis of internal forces in inclined columns and their connected members. For rare earthquakes, comparative calculations using static elastoplastic analysis and dynamic elastoplastic analysis are implemented to evaluate the structural and inclined column performance under severe seismic conditions. The study also includes stress analysis of inclined column joints and their connected floor slabs under different seismic levels. Results demonstrate that the overall structure meets seismic performance objectives, with inclined columns remaining undamaged during earthquakes, thereby satisfying engineering safety requirements. |
