摘要:
基于三维数字图像相关(3D-DIC)技术,研究框架填充墙在不同加载阶段下的Mises应变场、裂缝宽度和平面内/外(IP/OOP)位移场的变化规律。结果表明:当墙体加载至峰值荷载的70%~80%时,主裂缝轮廓基本形成,裂缝宽度为0.96~1.97 mm;当墙体加载至峰值荷载时,最大裂缝宽度达3.81 mm;墙体平面外曲面呈现类似二次曲面的形态,平面外位移幅值从墙体中心向四周依次递减;墙体各个区块内平面内位移幅值接近,主裂缝分割的各个区块平面内/外位移场呈现对称分布规律。
Abstract:
Based on three-dimensional digital image correlation(3D-DIC)technique, the Mises strain field, crack width and in-plane/out-of-plane(IP/OOP)displacement fields of the frame infilled wall at different loading stages were investigated. The results show that unde 70%-80% peak load, the main crack contour basically forms, and the crack width is 0.96-1.97 mm; unde the peak load, the maximum crack width is 3.81 mm. The outer surface of the wall resembles the shape of a quadric surface, the OOP displacement amplitude value decreases from the center to the edges of the wall. The IP displacement amplitude values of each block of the wall are similar, and the IP/OOP displacement fields of each block divided by the main crack presents the symmetrical distribution.
