Rapid structure health monitoring method for whole construction and operation stage of fabricated super high-rise structure

Abstract

The invention discloses a rapid structure health monitoring method for the whole construction and operation stage of an assembly type super high-rise structure, and the method comprises the steps: gradually installing data collection equipment along with the progress of the construction progress of an engineering project; structural vibration data in the construction process are collected and analyzed; establishing a structural finite element model along with the engineering construction progress; evaluating the safety in the construction process according to the difference between the actually measured modal parameters of the structure and the modal parameters of the calculation model; after construction is finished, the structural finite element model is corrected according to overall vibration data of the structure; structure vibration data are collected and analyzed regularly in the operation stage; and carrying out comparative analysis on the structure actual measurement modal parameters in the operation stage and the corrected finite element model modal parameters. The structure state change condition in the whole engineering construction process can be monitored in time, rapid safety evaluation of the construction process is achieved so as to guide actual construction, and real-time safety state evaluation is conducted on the structure in the structure operation process so that potential safety hazards of the structure can be found in time.

Description

technical field [0001] The invention relates to a rapid structural health monitoring method for the whole stage of construction and operation of a prefabricated super high-rise structure, belonging to the technical field of prefabricated super high-rise structure health monitoring. Background technique [0002] Prefabricated super high-rise buildings are a new structural form strongly advocated by the state. Due to their huge cost, complex structural form, long service life and the need for additional installation of structural accessories, the construction error control and operation of the structure during construction During this period, the structural safety, applicability and durability requirements are more stringent. In order to ensure the safety of the structural construction process, control structural construction errors, and ensure structural safety during the operation process, real-time structural health tracking and monitoring of the structure must be carried o...

Problems solved by technology

[0005] (1) Due to the manual input and related analysis of environmental vibration data involved in the construction process of the traditional structural monitoring system, the whole process from data collection to the conclusion of structural safety assessment takes a long time, which cannot meet the rapid construction progress of prefabricated structures Require;

[0006] (2) At present, the structural health monitoring method for the whole stage of construction and operation of prefabricated super high-rise structures is still blank, and there is no full-stage structural health monitoring method for prefabricated super high-rise structures.
