【摘要】 为测量隔震支座上下法兰的相对水平位移,提出一种基于斜角坐标系的测量方法。该法通过测量两个斜交方向上的位移,即可得到隔震支座平面位移的大小及方向。通过室内模型试验验证了该法的准确性,已应用于北京新机场航站楼核心区隔震支座上下法兰相对水平位移原位监测中。更多还原

【Abstract】 In order to measure the relative horizontal displacement of the upper and lower flange plates of the isolation bearing, a measurement method based on the oblique coordinate system is proposed. By measuring the displacement in two oblique directions, the magnitude and direction of the plane displacement of the isolation bearing can be obtained. The accuracy of the method is verified by the indoor model test. It has been applied to the in-situ monitoring of the relative horizontal displacement of the upper and lower flange plates of the isolation support in the core area of the Beijing New Airport Terminal.更多还原
