Embodiment Construction

[0015] The present invention is aimed at the early warning method for the abnormal seismic performance of building anti-seismic supports and hangers, comprising the following steps:

[0016] 1) An acceleration sensor is installed in the middle of the anti-seismic bracing of the anti-seismic support and hanger to monitor the acceleration response of the anti-seismic bracing caused by environmental loads;

[0017] 2) Process the raw data acquired by the acceleration sensor arranged in step 1), select the monitoring data under n-day intact state, take 10 minutes as the calculation interval, and calculate the natural vibration period T and the acceleration root mean square value R respectively;

[0018] 3) Call the calculation result in step 2) to calculate the daily average value T of the natural vibration period T in units of days D and the daily mean value R of the root mean square value of acceleration R D , using the method of linear regression to establish T D and R D The...

Abstract

The invention discloses an abnormal early-warning method for the earthquake resistance of a building earthquake-resistant support hanger. The method includes the steps that an acceleration sensor is installed in the middle of an earthquake-resistant slant support of an earthquake-resistant support hanger and used for monitoring an earthquake-resistant-slant-support acceleration response caused byan environmental load, original data of the acceleration sensor is obtained, then structural natural periods of vibration and acceleration root mean square values of multiple sets of data are calculated, a relevance model of the structural natural periods of vibration and acceleration mean square roots is established with the linear regression method, the slope of a linear regression model can beobtained with the least square method, and therefore three standard early-warning indexes are established. When the measured early-warning indexes are over then the standard certain range, it is shownthat the earthquake-resistant support hanger needs to be repaired. By means of the abnormal early-warning method, early warning can be accurately provided for the earthquake-resistant support hanger,the whole safety of the earthquake-resistant support hanger under the earthquake effect is kept, the aim of reducing and positively avoiding secondary disaster is thus achieved, and the effect is rarely considered in the past.

Description

technical field [0001] The invention belongs to the technical field of structural health monitoring, and in particular relates to a fault warning and state monitoring method for building supports. Background technique [0002] Building support failure warning and status monitoring According to the operating rules of the components or the possible precursors obtained from observations, before the support and hanger actually fails, timely forecast the abnormal situation of the support and hanger, and take corresponding measures to minimize the damage caused by the earthquake during the earthquake. Losses caused by hanger failure. [0003] In addition, few people at home and abroad are paying attention to the performance early warning of seismic supports and hangers. However, with the development of the times and social progress, people are no longer satisfied with the safety of living, but are pursuing comfort and satisfaction. With the increasing scale and complexity of com...
