Loading test on box culvert subjected to fault displacement

This paper summarizes loading test results of RC box culverts with two tunnels subjected to fault displacement. The specimens are 1/4 scaled model, supported by pin bearing as the fault crossing at 45 degrees of the tunnel axis and loaded vertically at the top slab to reproduce the soil pressure. Lo...

Summary:This paper summarizes loading test results of RC box culverts with two tunnels subjected to fault displacement. The specimens are 1/4 scaled model, supported by pin bearing as the fault crossing at 45 degrees of the tunnel axis and loaded vertically at the top slab to reproduce the soil pressure. Loading up to highly nonlinear region which greatly exceeded the yielding of reinforcing bars is performed and displacement transducers, strain gauges, image processing and optical fibers are utilized for measurements. The failure mode of RC box culverts subjected to fault displacement is clarified and their ductility is verified by test results. Experimental results will be used as the benchmark for design methods and damage evaluation by nonlinear analysis.
