摘要 密肋复合墙是由钢筋混凝土与轻质填充砌块组成的一种网格式抗震墙,高宽比是影响抗震墙抗震性能的重要因素之一。本文在密肋复合墙低周反复荷载试验的基础上,介绍了不同高宽下密肋复合墙的破坏形态,分析了高宽比对墙体承载力、延性、刚度等抗震性能的影响,与混凝土墙进行了对比,并就其原因进行了探讨。研究表明:密肋复合墙破坏特点、延性性能受高宽比影响的变化规律与混凝土墙有着较大的区别;密肋复合墙高宽比小于3.0时,墙体以剪切破坏形态为主;高宽比对于密肋复合墙延性性能的影响较小,高宽比小于1.0的低矮密肋复合墙亦可设计为具有良好延性的抗侧力构件。研究结果对于不同高宽比密肋复合墙体的抗震设计具有一定的参考意义。 Multi-grid composite wall is a type of seismic walls,which is made up of reinforced concrete members and light-weight in-filled blocks.Aspect ratio(ratio of wall height to width) is one of the important parameters which effect on seismic performance of the seismic walls.Based on the previous low-cycled loading tests,failure types of multi-grid composite walls of different aspect ratios were presented in this paper.Effect of aspect ratios on seismic performance of the multi-grid composite walls such as load-carrying capacity,ductility,and stiffness were investigated,and compared with those of reinforced concrete seismic walls.Results show that effect of aspect ratios on failure characteristics and ductility of multi-grid composite walls are different with those of reinforced concrete seismic walls.When the aspect ratios are smaller than 3,failure of the multi-grid composite walls is dominated by shear failure,and aspect ratios have little influence on the ductility and energy dissipation capacity of the multi-grid composite walls.Low multi-grid composite walls with aspect ratios smaller than 1 also have good ductility and energy dissipation capacity.Results in this paper provide certain reference for seismic design of multi-grid composite walls with different aspect ratios.
