摘要：
In order to meet the needs of the development of low rise assembly structure in rural areas, a fabricated lightweight steel frame-composite light wall structure is proposed in this paper. The lightweight steel frames are used to bear the vertical loads, the single-row-reinforced recycled concrete wallboards are used as lateral members to resist most horizontal earthquake loads, and the thermal insulation wall can be formed by the wallboard, EPS insulation modules and fly ash blocks. Four fabricated lightweight steel frame-composite light wall structures and one lightweight steel frame structure were tested under low cyclic load. The influences of wall reinforcement spacing and structural form (whether or not composite fly ash block) on the seismic performance of this new structure were analyzed. The results show that the lightweight steel frames and the single-row-reinforced recycled concrete wallboard can work well together, and the structure has two clear seismic resistance lines. Because of the use of EPS insulation modules and fly ash blocks, the structure has good anti-seismic and thermal insulation ability. Reducing spacing of bars or compositing fly ash blocks can significantly improve the seismic performance of the structure. Based on JGJ 138-2016 'Code for design of composite structures', the calculation formula of shear bearing capacity of this kind structure was proposed. The calculated results are in good agreement with the test results. © 2020, Editorial Office of Journal of Building Structures. All right reserved.
