全域拓扑桥 | 2019

该项目位于同济大学建筑与城市规划学院，桥梁跨度12米，可承载20名成年人同时步行安全通过。项目采用金属空间打印与碳纤维编织复合建造，充分发挥了两种材料及工艺的卓越性能。前期应用动力学原理及拓扑优化找形，并努力减少支撑杆件形成相当轻盈的结构。利用金属打印造型自由的特点制造主体龙骨及边梁。碳纤维与玻璃纤维缠绕形成的桥梁主体部分。踏步与扶手经受力及结构优化后借由应力线模拟编织路径。纤维自重超轻而固化后高强度的特点允其经由金属龙骨成为主要的受力承重结构。在纤维配比上，首先用玻璃纤维打底，接由碳纤维强化，考虑结构强度与性价比，达到了“之间”状态。

The composite construction of metal printing and carbon fiber braiding gives full play to the excellent performance of the two materials and processes. Early application of dynamics principles and topology optimization to shape and strive to reduce the formation of support members to form relatively light structures. The main body keel and side beam are manufactured by using metal printing's characteristics freedom of design. After the step and the handrail are subjected to the force and structural optimization, the weave path is simulated by the stress line. The light weight and high strength of the fibers allow them to become the main load-bearing structures through metal keels. In the fiber ratio, the first use of glass fiber base, followed by carbon fiber reinforcement, considering the structural strength and cost performance, reached the "between" state.
