Experimental Study on Compressive Strength of Ultrahigh Performance Concrete Prefabricated Wall Structure

In order to study the influence of two parameters, height-thickness ratio and reinforcement ratio, on compressive performance prefabricated recycled concrete block-filled core walls, author proposes a test method for strength wall structures. this method, 9 walls dry full-fill masonry are used, measuring device arrangement points designed carry out loading test. The results showed that can significantly improve axial bearing capacity wall, but out-of-plane displacement unreinforced is smaller than reinforced wall. larger height-to-thickness better ductility wall; measured value core-filled mean coefficient variation standard calculated were 1.49 0.13, respectively. 34% 68% higher value. conclusion, based data GB 50003–2011 “Code Design Masonry Structures,” theoretical calculation formula given.
