摘要:
The recycled aggregate concrete shear wall with expandable polystyrene (EPS) insulation modules and single layer of reinforcement was proposed. This shear wall is composed of insulation blocks, recycled aggregate concrete, single layer of reinforcement, special shaped edge columns, and mortar layers. Quasi-static tests of two full-scale shear wall specimens were conducted under low-cycle reversed loading. One of the specimens was a single-layer reinforced recycled aggregate concrete shear wall with EPS insulation blocks, while the other specimen was a single-layer reinforced recycled aggregate concrete shear wall without heat insulation blocks. Load-carrying capacity, ductility, stiffness, energy dissipation, and failure mechanism were compared. The shear capacity calculation formula of single layer reinforced recycled aggregate concrete shear wall with heat insulation blocks was proposed, the results from which fit well with the test results. The conclusions are drawn that single layer reinforced recycled aggregate concrete shear wall with insulation blocks has dramatically increased load-carrying capacity, lower stiffness degradation, better ductility, and significantly higher energy dissipation compared with one without insulation blocks; and that single layer reinforced recycled aggregate concrete shear wall with insulation blocks could be used in low-rise and multi-story buildings in the rural areas. ©, 2014, Science Press.
