Design, Manufacturing, Analysis and Implementation of Thick Solid FRP Composite Miter Blocks
Majority of hydraulic structures are built with conventional materials such as steel and reinforced concrete. These structures have been corroding and deteriorating within few years of service life. As a result, non-corrosive FRP (Fiber Reinforced Polymer) composites are emerging as alternatives for hydraulic structures. In this research, feasibility of FRP composites in designing miter blocks for lock gates is examined. Miter blocks, which are at present made with steel, create a continuous vertical line of contact between two closed miter gate leaves. These blocks are exposed to harsh service conditions as well as hydrostatic, hydrodynamic and mitering forces. Compressive forces are the most dominant forces that they have to withstand under opening and closing of gates. In this research, FRP miter blocks have been designed by utilizing off-the-shelf FRP products. FRP miter blocks were tested in compression, bending, and fatigue loads. Experimental results showed high reserve capacity of blocks beyond the service stresses. In addition, finite element analysis of a thick FRP composite block has been performed to correlate with the experimental results as well as to present its thermal behavior.
