EXPERIMENTAL STUDY ON COMPRESIVE MECHANICAL PERFORMANCE OF THERMAL INSULATION SMALL CONCRETE BLOCK WALL

通过不同配筋构造的保温承重复合混凝土小型空心砌块砌体的轴心受压和偏心受压试验,重点考察保温构造层以及水平钢筋的布置方式对墙体受压承载力及变形性能的影响,分析不同受压状态下墙体的受力性能和破坏特点。研究表明,满布水平钢筋网片更有助于使保温层与主承重砌块共同工作,保温层可提高墙体受压承载力,复合砌块墙体受压承载力实测值高于规范公式计算值。

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.
