摘要:
以混凝土材料、配筋率(钢筋间距)和配筋形式为主要参数,完成了两组共12块墙板单元的平面外力学性能试验,分析了墙板的破坏形态、承载能力和挠度变化规律。研究结果表明:普通混凝土墙板与再生混凝土墙板破坏特征相似,均产生压弯破坏,但再生混凝土试件脆性更为显著;相同配筋情况下,混凝土材料对试件承载力影响不大;在低配筋率的情况下,提高配筋率(减小钢筋间距)可有效提高墙板平面外承载能力;当量配筋情况下,钢筋直径较粗、间距较大的墙板具有更高的承载能力,但变形能力较弱。
Abstract:
Taking the concrete material, ratio of reinforcement (reinforcement spacing) and reinforcement form as main parameters, two groups of 12 wallboards are tested under out-of-plane static loads. The failure mode, bearing capacity and deflection of wallboards are analyzed. The results show that:the ordinary concrete and recycled concrete wallboards have similar characteristics of flexural failure, but the brittleness of recycled concrete is more obvious; under the same reinforcement ratio, the concrete material has little effect on the bearing capacity of specimens; in the case of low reinforcement ratio, the action of increasing the reinforcement ratio (decreasing the space of steel bars) can effectively improve the bearing capacity of the wallboard; under the same reinforcement ratio, the wallboard with larger diameter and larger spacing has higher bearing capacity, but less deformation after failure.
