The automated health monitoring of load-bearing frame elements high-rise building: taking into account the temperature factor
Abstract: To ensure the required level of safety, both at the construction stage and during the building operation period, the systems for automated long-term structural health monitoring acquire an important role. The system provides early diagnosis of changes in the stress-strain state of structures and localization of such changes.
In the article the questions of the automated structural health monitoring of high-rise buildings of high-rise buildings using tilt angle sensors – inclinometers. Indicators of sensitivity and long-term stability of the metrological characteristics of inclinometers make it possible to register almost any deformation changes in the geometry of the building's supporting frame, including those due to temperature variation. High sensitivity in combination with the wireless interface allows you to quickly and cost-effectively organize the information-measuring monitoring network, and if necessary – to change its configuration. As a basis for processing the monitoring data, a correlation analysis of the angles of the building framework columns inclination is proposed.
The correlation analysis of the inclination angles of the columns of the building frame is proposed as a basis for processing the monitoring data.
The monitoring data of a high-rise building in Minsk are given. Revealed a significant correlation the angles of monolithic columns inclination of the building and temperature. The author's method of introducing an amendment to compensate for the temperature deformation factor is proposed.
Keywords: monitoring, inclinometer, load-bearing framework, angular deviation, deformation, godograph.
