Abstract

Abstract

Mao Yisheng Public Bridge in Chongqing is the first all FRP truss bridge made of pultruded profiles in China, with a span of 20 m and width of 2.0 m.Based on which, the behavior of pultruded profiles, some connection methods and structural system of the bridge were introduced.The static and dynamic behavior of the FRP pultruded bridge were studied.The bridge has been tested twice when it was pre-installed in the factory and 174 d after it opened.A dynamic behavior test was conducted also.All test cases were simulated using FEA program SAP 2000.The results show that the FRP truss bridge has a higher stiffness and load bearing capacity.It has a 2.09 mm deformation under 45% of design load, and the first vertical natural frequency is about 10.8 Hz.The results from FEA match the test results very well, showing that it is reasonable to consider the FRP truss members as the linear-elastic link elements.
