“…e lowest one-skin block of the core-filled wall uses a sweeping block to simulate the masonry process of such a wall in an actual project. e corefilled wall is built without mortar, layer by layer, and the main masonry process [10,11] is as follows: (1) Check whether the upper surface of the bottom beam is level with a laser line projection instrument. (2) According to the actual size of the wall, use the template as a corner to ensure the verticality of the wall.…”

“…Both failures are dry joint failures and belong to the brittle failure mode, and the realization of the expected ductile failure mode under earthquake action is one of the main factors in ensuring the seismic performance of the structure. erefore, in order to realize the ductile failure of PPSDC, the plasticity of the connecting steel plate should be fully utilized, ensure punching failure of concrete and anchor failure of steel embedded parts, and not occur before yielding of the connecting steel plates, improving the ductility of dry joints [11].…”

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