DEVELOPMENT OF DOUBLE LAYER SPACE TRUSS WITH ULTRA HIGH STRENGTH FIBER REINFORCED CONCRETE

Abstract

This study aims to develop a truss system by precast concrete members using Ultra High Strength Fiber Reinforced Concrete, UFC, which shows ductile behavior and high durability.
A pyramid shaped truss with prestressed truss members were designed, and a constructional experiment was carried out. The result of cyclic loading test on the pyramid shaped truss demonstrated that this structure could be applied to an actual double layer space truss structure. Finally, the failure process of the structure was described in this paper.
