玻化微珠保温混凝土是一种通过加入新型无机绿色保温材料——玻化微珠来降低导热系数,提高保温性能,最终达到保温承重一体化的高性能混凝土。本文通过对2片不同剪跨比的玻化微珠保温混凝土中高剪力墙进行拟静力试验研究与承载力理论计算,对比分析其破坏形态、承载力、特征位移、割线刚度以及滞回耗能等特性,确定新型墙体的承载力计算公式。试验及分析结果表明:玻化微珠保温混凝土中高剪力墙表现出较好的延性和耗能能力;增大剪跨比对提高玻化微珠保温混凝土中高剪力墙的延性以及增强其耗能能力具有较明显的效果;普通剪力墙承载力计算公式同样适用于玻化微珠保温混凝土中高剪力墙,在设计中可参照普通混凝土剪力墙进行截面设计。
Vitrified beads insulation concrete is a kind of high-performance concrete with thermal insulation load-bearing integration by adding a new inorganic green insulation material - vitrified beads to reduce the thermal conductivity, improve the thermal insulation properties. In this paper, through the quasi-static test and the theoretical calculation of the bearing capacity of two shear walls with different shear-span ratios, the failure modes, Energy consumption and other characteristics to determine the bearing capacity of new wall formula. The results of tests and analysis show that the high shear walls of vitrified micro-beads in thermal insulation concrete show good ductility and energy dissipation capacity. Increasing the shear-span ratio improves the ductility of high-shear walls in vitrified micro-beads thermal insulation concrete and enhances its consumption Ability has a more obvious effect; ordinary shear wall bearing capacity of the formula is also applicable to glass beads in the insulation of the mid-high shear wall, the design can refer to ordinary concrete shear wall section design.
