摘要
针对砌体结构在地震中表现出的较低抗震能力问题,利用ABAQUS搭建仿真实验环境,采用混凝土本构计算方法计算砌体性能,并根据详细的建模参数选择整体式建模.研究结果表明:当位移值为2.86 mm的时候,所设计的模型在骨架曲线下的最大荷载值为238.14 kN;模型的开裂位移和极限位移分别高达1.58、2.56 mm;开裂荷载和极限荷载分别高达213.52、238.14 kN.该模型具有更好的抗震性能,能够接受更大的压力变化.创新性设计的斜向交叉钢筋网水泥砂浆加固墙体方法,可以改善当前的砌体墙结构力学性能,不仅可为砌体结构的抗震加固提供经济有效的解决方案,还能为未来的建筑设计和施工实践提供新的视角.
This study addresses the issue of low seismic resilience of masonry structures in earthquakes.ABAQUS was employed to construct a simulation test environment,and a concrete constitutive calculation method was utilized to assess masonry performance.Furthermore,integral modeling was selected based on the specific modeling parameters.The results demonstrate that when the displacement value reaches 2.86 mm,the maximum load value of the designed model under the skeleton curve reaches 238.14 kN.Additionally,the cracking displacement and ultimate displacement of the model are observed to be 1.58 mm and 2.56 mm,respectively.The cracking load and ultimate load are 213.52 and 238.14 kN,respectively.The model displays enhanced seismic resilience and is capable of accommodating more significant pressure fluctuations.This novel design of the diagonal cross steel mesh cement mortar reinforcement method can enhance the mechanical properties of the existing masonry wall structure.It offers an economical and effective solution for the seismic reinforcement of masonry structures and provides a new perspective for future architectural design and construction practices.
