Abstract: In the paper, a new type of load-bearing thermal insulation composite concrete small hollow block masonry with different reinforcement detailing were studied by the tests under axial and eccentric compressive loads, focusing on the impact of insulating layer, as well as the arrangement of horizontal reinforcement on the wall compressive bearing capacity and deformation performance.Loading and damage characteristics of the wall subjected to different compressive states were analyzed.Studies have shown that the level of steel mesh covered with even more help to make insulation layer work together with the main load-bearing building blocks, and the insulating layer can enhance the bearing capacity of the wall, and the measured bearing capacity of composite block wall is higher than the value of standardized formula.
