“…e loading system is continuous loading; before the formal loading, the specimen is preloaded (10% estimated load) for 3 to 5 times; in the early stage of specimen loading, the control method of equipment loading is test force control, and the control loading rate is 2.0 ± 0.5 kN/s; when the load is applied to 70% of the estimated load, the control method of equipment loading is switched to displacement loading [13], the loading rate was maintained at 0.2 ± 0.01 mm/min, and the load increasing rate was not much different from that when the test force was controlled. e specific test steps are carried out in accordance with GB/T 50129-2011 "Standards for Test Methods of Basic Mechanical Properties of Masonry.…”

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.
