Abstract

A cable-stayed pedestrian bridge with an S-curved girder called Shake Hands Bridge is proposed. This type of bridge overturns the traditional notion of linearly constructed cable-stayed bridges. Cables support the S-curved girder from intersecting inclined towers creating a three-dimensional effect. The aesthetic design of the proposed bridge is examined using a model, a 3D computer-aided design diagram, a computer graphics diagram and a video. The proposed bridge is attractive and impressive, in harmony with the surrounding environment, and is considered to have great presence and to be an attraction in itself. From a structural point of view, it is found that the inclined tower has the effect of reducing the axial force of the girder and the tower itself and suppressing bending of the girder. On the other hand, it is found that the S-curved girder is more affected by torsion than a straight girder, but that there is no problem with safety. In addition, deflection of the girder due to live loading also satisfies the allowable value, there is no problem due to vertical or horizontal vibration, and the serviceability is sufficiently secure. Therefore, the proposed bridge is considered to be highly feasible.

摘要

提出了一个带有 S 形弯曲梁的斜拉人行天桥，称为握手桥。这种类型的桥梁颠覆了线性构造斜拉桥的传统观念。电缆支撑 S 形弯曲梁，使其与斜塔相交，从而产生三维效果。使用模型、3D 计算机辅助设计图、计算机图形图和视频来检查拟议桥梁的美学设计。拟建的桥梁具有吸引力且令人印象深刻，与周围环境相协调，被认为具有很强的存在感，本身就是一个景点。从结构上发现，斜塔具有减小大梁和塔本身的轴力，抑制大梁弯曲的作用。另一方面，发现S型曲梁比直梁受扭转的影响更大，但不存在安全问题。此外，由于活载引起的梁挠度也满足允许值，不存在垂直或水平振动引起的问题，使用性能有足够的保障。因此，建议的桥梁被认为是高度可行的。
