Title:
REINFORCED CONCRETE STRUCTURE DAMAGE QUANTITATIVE MONITORING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/046430
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of civil engineering, and relates to a reinforced concrete structure damage quantitative monitoring method and system. The method comprises: acquiring an optical fiber strain signal and section design parameters of a longitudinal tensile reinforcing bar of a reinforced concrete beam (101), wherein the section design parameters comprise geometric parameters and material performance parameters, the geometric parameters comprise a section width, a section height, a section equivalent height, a protection layer thickness and a reinforcing bar area, and the material performance parameters comprise concrete compressive peak stress, concrete initial tangent modulus and reinforcing bar initial tangent modulus; establishing a section analysis model according to the section design parameters (102), wherein the section analysis model comprises a concrete damage stress-strain relation model and a reinforcing bar damage stress-strain relation model; and inputting the optical fiber strain signal into the section analysis model to obtain a damage index and a moment-curvature curve of each section (103). The present invention realizes quantitative monitoring on damaged sections.
