Experimental Research on Bearing Capability of Energy-Saving Block and Hidden Multi-Ribbed Frame Walls under Eccentric Compression

Four pieces of 1/2 scale energy-saving block and hidden multi-ribbed frame wall models are studied experimentally under the eccentric compression.Failure processes,cooperative working action,failure modes and bearing capability are analyzed to obtain the bearing capability calculation formula.Research indicates that the result of the calculation formula agrees conservatively with the test results.And the formula may be used to calculate the bearing capability of this type of wall.With increasing the eccentricity,the failure modes change from small eccentric compression to large eccentric compression,and the failure load decreases,while the ductility increases.These phenomenon coincide with the failure of the reinforced concrete structures.The conclusion shows that the multi-ribbed frame and the blocks can work well together,the structure fails due to material damage,out-of-plane axial bending failure doesn't occurs.
