【摘要】 在冷轧带肋钢筋应用情况研究基础上,通过11个剪力墙试件的拟静力试验研究,探讨了将冷轧带肋钢筋用作混凝土剪力墙分布筋的可行性.重点分析探讨了采用暗柱或翼缘柱、采用焊接网或绑扎网及暗柱箍筋间距的变化等对剪力墙的延性、变形能力、能量耗散能力等的影响.指出冷轧带肋钢筋可用于无抗震设防及抗震设防烈度不超过8度丙类建筑的钢筋混凝土房屋剪力墙的分布筋.更多还原

【Abstract】 Based on the application of cold-rolled ribbed reinforcement,the feasibility of using cold-rolled ribbed steel in concrete shear wall is investigated by conducting 11 experiments on the seismic behavior of cold-rolled ribbed reinforced concrete shear wall.The ductility,deformation and energy dissipation of shear wall are affected by some factors,including embedded columns or flange columns,welded bar-mesh reinforcement or binding bar-mesh reinforcement and the change of stirrup spacing for embedded columns.The results of the analysis show that it can be used for distributing reinforcing steel bar under 8 level seism zones.更多还原
