摘要
研究开发了钢筋混凝土底框架商住楼建筑物火灾现场竖向变形观测仪器,即时观测着火建筑框架柱竖向变形,预测底框架商住楼建筑物的倒塌时间。主要设备包括:高倍望远镜、数码照相机、笔记本电脑等。拍摄的图像经Matlab软件处理,以备倒塌预警程序调用。经电子应变仪试验验证,观测精度误差为0.8%。
Vertical deformation observation instrument in fire of bottom RC frame business-living building has been researched and developed. This instrument will make real-time tracking on vertical deformation of bottom RC frame business-living buildings and forecasted the collapse time in fire. The main equipments of the instrument are high-power telescope, digital camera, note book PC etc. Matlab was used to the picture taken from digital camera for collapse forecast program. The error of detection is 0.8% tested by electrical strain gauge.
