摘要:
为适应农村自建房的局限性和低成本要求,提出内置式新型空心砌块墙体构造方案。内置式墙体充分利用单排孔空心砌块外形特点,砌块本身作为构造暗柱、芯柱或斜撑的模壳,免去模板支护过程,省时省料。进行了4榀内置式构造方案墙体水平低周往复荷载试验,研究了不同构造方案下墙体的破坏过程、破坏形态、承载能力、位移延性和耗能能力等,分析了墙体破坏机理。研究表明:内置构造暗柱、芯柱或斜撑使墙体承载力和刚度明显提高,位移延性和耗能能力显著改善。经综合分析,建议最优构造方案为墙体两端构造暗柱和芯柱集中布置,同时于墙体中部适当增设芯柱,并通过水平拉结筋网片保证构造暗柱和芯柱的有效拉结和共同工作。
Abstract:
In order to adapt to the limitations and low cost requirements of rural self-built housing, a kind of new hollow block walls with built-in constructional details is proposed. The built-in walls fully utilized the characteristics of single hole hollow block shape by using block itself as a formwork of structural embedded columns, core columns or diagonal bracings, which eliminates template supporting process and saves time and material. Low-cyclic horizontal loading tests were performed on four pieces of hollow block walls with built-in constructional details. Based on the experiments, the damage process, failure mode, load carrying capacity, displacement ductility and energy dissipation capacity were studied and the failure mechanism of walls were discussed. The test results indicate that the bearing capacity, stiffness, ductility and energy dissipation capacity of walls with build-in structural embedded columns, core columns or diagonal bracings were improved obviously. Through comprehensive analysis, the optimal constructional details for wall are suggested that structural embedded columns and core columns centralized layout at both ends, and appropriate core columns are added in the centre of the walls, while through the horizontal steel tie mesh to ensure that the effectively and cooperation work of structural embedded columns and core columns.
