Abstract
This feasibility study examined the design and the serviceability of a newly proposed pedestrian slab bridge using GFRP pultrusion profiles bonded together by adhesive layers. The innovative feature is the appropriate adoption of semi-fixed support conditions with anchor bolts at both ends, in order to sharply reduce the bending deflection and to drastically improve the economic efficiency. In this paper, the validity of the development of the new type bridge is verified from results of a material design and tests, a trial structural design and partial model tests with real size. In addition, the practical design deflection calculation formula which can consider the shearing deformation is proposed, and the examination of the review of the limiting value which influences the economical efficiency directly is also carried out.
