During last twenty years, the utilization of FRP (Fiber Reinforced Polymer) technology has provided interesting solutions for the realization of pedestrian bridges for public or industrial use. More than 100 footbridges have been installed worldwide so far. Their spans are generally in the range from 5 to 30 m. Almost all of them are made up of polyextruded glass-fiber reinforced plastic profiles, which take on the classical shapes of steel profiles and seek modularity through specular symmetries. The paper describes the project Twin Shape Composed Beam (TSCB) supported by the CTI (Swiss Confederation s innovation promotion agency). The project aims at pushing the product beyond its usual shape by seeking new creative hints in the morphogenetic shapes found in diatoms, radiolars and the like. The basic idea is to produce a monocoque shell starting from the combination of identical spatial elements with different symmetries (central, axial, specular and so forth), mimicking the structure of diatoms and radiolars. This leads to the name TSCB, which clearly illustrates the objective of producing a module by combining small units. The project aims to study, develop and build a modular pedestrian bridge 18 m wide, characterized by a fast assembly-disassembly system. In particular the project follows different phases as: study and optimization of the geometry, structural analysis, monitoring, study and development of the fast assembly-disassembly system, analysis of the durability and the mechanical characteristics of the pedestrian bridge, and analysis of the dynamic behavior of the structure. The results of the analyses obtained in the different phases are here described.
