摘要
某大学图书馆主入口采用拱形结构以实现建筑效果,拱构件跨度为53.45m,矢高为10.70m,转换拱共转换13颗框架柱。通过对比纯拱转换方案与拱与斜柱共同转换两种不同方案,分析各方案的传力机制、内力对比,配筋结果,构造措施,性能化设计及失稳情况,比较两个方案各自的优势特点。并且结合两个方案的受力情况、经济性等因素寻求拱形转换构件在本项目中的最优矢跨比,可为类似工程设计提供一些参考。
The transfer arch with 53.45-meter-span and 10.70-meter-vector height is adopted to transfer 13 columns for the university library main entrance to meet the architect demands.Two different schemes are compared which are only transfer arch scheme and transfer arch with inclined columns scheme.Two schemes’features and advantages are analyzed from force-transferring mechanism,internal forces,reinforcement design,constructional measures,performance-based design and member buckling.Meanwhile,based on the internal force analysis and economic factor,the optimized rise-span ratio is obtained which can be a reference for other similar projects.
