近景摄影测量在钢结构货架抗震稳定性方面的研究

Research of Close-Range Photogrammetric on the Seismic Stability of the Logistics Shelves

为了掌握物流货架系统的形变规律,评估物流货架系统的抗震稳定性,运用数码相机获取钢结构货架变形试验数据,推导三维时间基线视差法,进行测量数据解算,并结合有限元分析法对钢结构货架变形进行模拟分析,评定钢结构变形。最后,对某公司物流货架进行货架的抗震稳定性分析实验,结果表明,货架的变形均小于10 mm,抗震稳定性良好。用该方法监测钢结构变形可以得到准确的结果,对快速评定货架稳定性具有积极意义。

In order to grasp the deformation law of the logistics and warehousing steel shelving systems , assess the seismic stability of the logistics and warehousing steel shelving systems , use digital cameras to get steel shelves deformation test data , deduce the 3D time baseline parallax method to solve measurement data , combine the finite element analysis method to simulate and analyze the deforma-tion of the steel structure rack and assess the steel structure deformation .At last, a logistics shelf was taken as an experiment exam-ple.The results showed that the deformation of the shelves was less than 10mm, the seismic stability was good;steel deformation de-tected by this method could reach accurately results , it had a positive meaning for rapid assessment of shelf stability .
