数码摄影测量技术在填充墙框架抗震试验中的应用

Application of Digital Photogrammetry in Experimental Study on Seismic Behavior of Infilled Frames

将数码摄影测量(DP)技术引入填充墙框架受力全过程的位移场测量,研究DP技术应用于填充墙框架结构抗震试验研究的可行性.数据分析结果表明:采用DP技术的测量结果与传统位移计所测结果吻合良好.通过DP技术进一步得到在不同位移幅值下填充墙的剪切滑移破坏情况及框架柱的变形特征.

The digital photogrammetry(DP) technology is introduced to the displacement-field measurement of the infilled frame, and the feasibility of applying the DP technology to the seismic test of infilled frame structures is discussed. The test results show that, the measurement taken by the DP technology agrees well with that taken by the traditional displacement meters. Furthermore, the shear-slip failure of the infilled wall under different displacement amplitude and the deformation feature of the frame columns are obtained by the DP technology.
