该项目提出了一种新的研究，在结构设计和分析的超透明人行天桥完全由玻璃板在一个双层，索状，压缩配置。桥梁的缆索形式最大限度地提高了其结构性能，并最大限度地减少了材料和资源的使用。该项目的结构形式是使用3D图形静力学（3DGS）开发的，这是一种基于几何的结构设计方法，可以在三维空间中广泛探索索状结构解决方案。使用3DGS方法会产生具有平面的多面体几何形状的结构形式。因此，3DGS不仅找到了有效的结构形式，而且其平面性约束有助于使用平板材料进行施工。目前的桥梁结构由三维多面体单元组成，如中空玻璃块，平面玻璃面通过使用透明的硅基物质压缩在一起（图1）。大桥的总跨度为10米（32.81英尺），桥面为1米，供行人通行。桥梁的非对称几何形状将显着改善桥梁在非对称和横向荷载条件下的行为。
This project presents novel research in structural design and analysis of an ultra– transparent pedestrain bridge made exclusively of glass sheets in a double layer, funicular, compression–only configuration. The funicular form of the bridge maximizes its structural performance and minimizes the use of materials and resources. The structural form of the project has been developed using 3D graphic statics (3DGS) that is a geometry-based structural design method allowing the extensive exploration of funicular structural solutions in three dimensions. Using the 3DGS method results in structural forms that are polyhedral geometries with planar faces. Therefore, not only does 3DGS find the efficient structural forms, but its planarity constraint facilitates the construction using flat sheet materials. The current structure of the bridge consists of three-dimensional polyhedral cells as hollow glass blocks with planar glass faces held together in compression by using transparent silicon-based substance (figure 1). The total span of the bridge is 10 m (32.81 ft) with a one-meter deck for pedestrian traffic. The asymmetric geometry of the bridge will significantly improve the behavior of the bridge under asymmetric and lateral loading conditions.
