Experimental Study on Seismic Behavior of Recycled Concrete Grill Walls with Axial Compression Ratio

Through the seismic behavior of 4 pieces of concrete grill wall by pseudo- static test, the test sample destruction shape, the skeleton curves under to the different wall material and the different axial compression ratio, consuming energy ability, the ductility coefficient were conducted the contrast research. The experiment indicates the test sample under the level reciprocation load and the axial action of force, destruction shape main perform for cutting destruction; After wall dehiscence, the rigidity rate of descent is quick, after achieving the ultimate load, the rigidity drop flatten out, the wall has the good ductility. By enhancing the axial compression ratio, it may enhance the wall the ductility, to consume energy the coefficient; the walls contained recycled concrete aggregate has good energy dissipation and seismic performance;
