Research Abstract

Fiber reinforced plastics (FRP) composites are being considered for structural members in bridge construction and rehabilitation as lighter, more durable alternatives to steel and concrete. The behavior of GFRP pultruded I beam with less than 300mm depth has been investigated by various researchers and research institutes. However for civil engineering applications and due to the approximately low elastic modulus of GFRP materials, the necessity for deep GFRP pultruded beams becomes crucial. This study firstly presents the behavior of GFRP pultruded I-600 beam and its connection under static and fatigue loadings. Secondly, it presents overview about the first practical application of proposed GFRP strengthening system to an existing I-girder highway bridge with deteriorated RC deck. The efficiency of the system was evaluated by using FEM analysis, and also was shown an outline of the procedure of the strengthening work. Finally, another application example of GFRP pultruded panel to the composite deck in highway bridge was introduced.
A super-light weight concrete using artificial lightweight aggregate is expected that use of super-light weight concrete can increase the seismic resistance and economical efficiency by reducing the excessive weight of structures. However, it is weak points against tensile strength and shear strength compared to normal weight concrete. In order to overcome those weak points, adding short fibers into super-light weight concrete was examined. This method was based on the idea that short fibers could increase the tensile strength of concrete according to the bridge construction effect. For the super-light weight RC beams with steel short fiber reinforcement, it could not be design formula to predict the shear loading capacity. In this study, we proposed modified formula focused on angle of cracking by shear loading, and the method came off arithmetic precision.
