Real-time monitoring method and the real-time evaluation method for seismic performance of building anti-seismic fupport post

Abstract

The invention discloses a real-time monitoring method and a real-time evaluation method for the seismic performance of a building anti-seismic fupport post. The method comprises the steps of installing a strain sensor in a boom of the anti-seismic fupport post, and installing an acceleration sensor in an inclined strut; recording the initial mass m of a construction electromechanical engineering facility, selecting monitoring data within a certain time length t1 as a calculation interval, calculating the self-vibration cycle average value Ttest and the static strain average value epsilon test1 of obtained original data after the installation of the anti-seismic fupport post and before the usage of the anti-seismic fupport post, and calculating the initial rigidity k of the anti-seismic fupport post based on the initial mass m and the self-vibration cycle average value Ttest; during the usage stage, selecting monitoring data within a certain time length t2 as a calculation interval, calculating the static strain average value epsilon test 2, the actual quality mtest of the construction electromechanical engineering facility and the resistant-lateral rigidity ktest. The invention discloses a real-time assessment method for the anti-seismic fupport post. According to the invention, the performance of the anti-seismic fupport post can be monitored in real time, so that the use health condition of the anti-seismic fupport post can be further evaluated. The early warning for maintenance and replacement is provided. The advantages of convenience, real-time performance, safety andthe like can be realized.

Description

Technical field [0001] The invention relates to a real-time monitoring method and a real-time evaluation method for the seismic performance of a building seismic support and hanger used in civil engineering. Background technique [0002] The structural health monitoring and evaluation system evaluates the reliability and safety of the structure by analyzing the dynamic response data collected by the sensors arranged on the structure, and provides basis and guidance for the maintenance, maintenance and management of the structure. [0003] Building seismic supports and hangers are important seismic measures for effective protection of mechanical and electrical equipment and pipelines. They are composed of anchors, reinforced booms, seismic connection members and seismic braces. According to the current national standard "Code for Seismic Design of Buildings" (GB50011-2010), non-structural components in buildings and their connections to the main structure need to be designed for ear...
