预制钢筋混凝土墙板加固砌体结构抗震性能研究

Seismic Behavior of Masonry Structures Strengthened with Precast Reinforced Concrete Wallboards

我国部分既有砌体结构建筑抗震性能差,对结构使用安全产生不利影响。为研究符合当代绿色施工环境下的老旧砌体建筑加固方法,基于传统砌体结构加固方法,将装配式理念与砌体加固相结合,深入分析了现有装配式板墙加固砌体结构的试验、理论及数值模拟研究成果。结果表明采用预制装配式混凝土板墙加固砌体结构可以较好提高其承载能力与变形能力,改善地震作用下砌体结构损伤机制。

In order to study the reinforcement methods of old masonry buildings in line with the contemporary green construction environment,based on the traditional reinforcement methods of masonry structures,this paper combined the fabricated concept with masonry reinforcement,and deeply analyzed the tests of existing fabricated slab wall reinforced masonry structures.The research results of theoretical and numerical simulation methods showed that the use of prefabricated concrete slab wall to strengthen masonry structure could better improve its bearing capacity and deformation capacity,and improve the damage mechanism of masonry structure under earthquake.
