St Philips Footbridge in Bristol: The Aesthetics of Thoroughly Responding to Constraints

In 1840, the inauguration of the Great Western Railway in southern England, connecting London and Bristol, changed part of the outskirts of Bristol to a major railway hub and a home for many rail-related activities. An area behind the station between the railway, the River Avon and the Bath Road, known as Temple Island, became restricted to rail use (workshops, depots and sheds) for more than 150 years, making it inaccessible and unattractive as the railway use decreased. The transformation of this area into a new centrally located neighbourhood is one of the most important urban development projects currently planned in Bristol. The new St Philips footbridge spans the River Avon, contributing to accessibility to the site. The bridge, a 50 m span and 4 m wide steel beam with a forked geometry, seamlessly hosts a ramp for disabled users and cyclists and a staircase to maximise functionality. The design approach to generate its shape was simultaneously structural, aesthetic and functional, innovatively solving a complex crossing problem.

布里斯托尔的圣飞利浦人行天桥:全面响应约束的美学

1840年,连接伦敦和布里斯托尔的英格兰南部大西部铁路的落成典礼,将布里斯托尔郊区的一部分改为主要的铁路枢纽和许多铁路相关活动的所在地。在铁路,雅芳河和巴斯路之间的车站后方区域,被称为圣殿岛,已被限制使用铁路(车间,仓库和棚屋)已有150多年的历史,随着铁路使用的减少,铁路难以进入且无吸引力。该地区向中心新街区的改造是布里斯托尔目前计划中最重要的城市发展项目之一。新的圣飞利浦人行天桥横跨埃文河,为该站点的通行性做出了贡献。这座桥是一个50 m跨度和4 m宽的钢梁,具有叉形几何形状,无缝地为残疾人士和骑自行车的人提供一个坡道,并为最大程度地发挥功能提供楼梯。生成形状的设计方法是在结构,美学和功能上同时进行,创新地解决了复杂的交叉问题。
