【摘要】 以浙江广厦职业技术大学木雕小镇校区图书馆项目为工程背景,针对其采用的高层大悬臂倾斜悬挂结构体系,通过建立精细化有限元模型对施工全过程进行数值模拟,并结合施工过程现场应力与变形监测数据,深入分析了倾斜钢吊杆、悬挑钢梁及顶部钢桁架等关键构件在支撑卸载与楼板浇筑等关键阶段的受力与变形规律。研究结果表明:有限元模拟能有效预测结构响应趋势,但实际施工中需考虑多种因素影响,凸显了过程监测的必要性;施工全程结构应力水平可控,变形量较小,验证了结构安全性与逆作法的可行性;钢梁与核心筒的刚性连接显著改变了倾斜钢吊杆的受力机制,使其呈现出上部楼层表现为悬挂结构、下部楼层表现为悬挑结构的独特复合受力特性。更多还原

【Abstract】 Based on the library project of Zhejiang Guangsha Vocational and Technical University’s Woodcarving Town campus, this study focuses on its high-rise cantilevered inclined suspension structural system. Through refined finite element modeling and simulation of the entire construction process, combined with on-site stress and deformation monitoring data, the mechanical and deformation behaviors of key components—such as inclined steel hangers,cantilever steel beams, and top steel trusses—during critical stages like support unloading and slab pouring were analyzed. The results indicate that finite element simulation effectively predicts structural response trends, but actual construction requires considering multiple influencing factors, highlighting the necessity of process monitoring.Throughout construction, structural stress levels remained controllable, and deformations were minimal, validating structural safety and the feasibility of the top-down construction method. The rigid connection between steel beams and the core tube significantly altered the force mechanism of the inclined steel hangers, resulting in a unique hybrid structural behavior: the upper floors exhibit suspension characteristics, while the lower floors demonstrate cantilever behavior.更多还原
