【摘要】：为改善异形柱框架结构的抗震性能,提出一种格构配筋再生混凝土L形柱框架-轻质填充墙结构。进行两个格构配筋再生混凝土L形柱框架-粉煤灰砌体填充墙结构的低周反复荷载试验,框架分为普通框架和带人字形支撑框架两种。基于试验,分析各试件的承载力、刚度、延性、滞回特性、耗能和破坏特征,找出结构损伤破坏的薄弱部位,阐明其屈服机制。研究表明:带人字形斜撑的格构配筋再生混凝土L形柱框架-轻质填充墙结构,承载力、延性和综合抗震性能均有显著提高。提出的格构配筋再生混凝土L形柱框架-轻质填充墙结构,简化了配筋,提高了工效,易于施工,成本较低,抗震性能良好。
[Abstract]:In order to improve the seismic behavior of special-shaped column frame structure, a lattice reinforced recycled concrete L-shaped column frame-light infilled wall structure is proposed. The low cycle cyclic loading tests of two lattice reinforced recycled concrete L-shaped column frames and fly ash masonry infilled wall structures are carried out. The frames are divided into two types: common frame and braced frame with herringbone shape. Based on the tests, the bearing capacity, stiffness, ductility, hysteretic characteristics, energy dissipation and failure characteristics of each specimen are analyzed, the weak parts of structural damage and failure are found out, and the yield mechanism is clarified. The results show that the load-carrying capacity ductility and comprehensive seismic performance of lattice reinforced recycled concrete L-shaped column frame-filled wall structure with herringbone oblique brace are significantly improved. The proposed lattice reinforced recycled concrete L-shaped column frame-light infilled wall structure simplifies the reinforcement, improves the working efficiency, is easy to construct, has low cost and good seismic performance.
