摘要

本文讨论了旋转运动对建筑的影响问题，并介绍了用于旋转事件和现象监测的光纤系统光纤旋转地震仪的土木工程应用。它是为长期的建筑监测和结构旋转记录而设计的。它基于Sagnac效应，可以直接检测单轴旋转运动，而无需任何参考系统。它能够检测信号幅度从10 rad/s到10 rad/s的宽范围内的旋转分量，以及频率从DC到1000 Hz。本文提供的数据显示了钢筋混凝土框架结构在不同楼层上的性能。通过将应用的传感器放置在建筑物的不同楼层进行了几次测量。实验室和现场测量结果表明，光纤旋转事件和现象监测系统是一种准确、适用于土木工程应用的设备。

Investigation of rotational motion in a reinforced concrete frame construction by a fiber optic gyroscope

Article history: Received 25 Mar. 2020 Received in revised form 01 Apr. 2020 Accepted 01 Apr. 2020 This paper deals with an issue of a rotational motion impact on a construction and presents civil engineering applications of a fiber optic rotational seismograph named Fiber-Optic System for Rotational Events & Phenomena Monitoring. It has been designed for a longterm building monitoring and structural rotations’ recording. It is based on the Sagnac effect which enables to detect one-axis rotational motion in a direct way and without any reference system. It enables to detect a rotation component in the wide range of a signal amplitude from 10 rad/s to 10 rad/s, as well as a frequency from DC to 1000 Hz. Data presented in this paper show the behavior of a reinforced concrete frame construction on different floors. Several measurements were carried out by placing the applied sensor on different floor levels of a building. The laboratory and in-situ measurements confirmed that Fiber-Optic System for Rotational Events & Phenomena Monitoring is an accurate and suitable device for applications in civil engineering.
