A method for evaluating the reuse performance of scrap steel components based on mechanical property quantification

Abstract

The present invention relates to the field of sustainable design of building steel structures, and specifically discloses a method for evaluating the reuse performance of scrap steel components based on the quantification of mechanical properties. S1: Developing a target component reusability evaluation system based on measured performance parameters; After completing the development of the evaluation system, an operator can obtain performance parameters by testing the target component, and finally use the developed system to complete the component reusability evaluation. The specific steps are as follows: S2: Using a three-dimensional scanning device to obtain the geometric configuration of the target component to be evaluated; S3: Using a modal test device to measure the vibration response of the component to be evaluated under specific excitation; S4: Using material property detection technology to obtain strength information of the steel component to be evaluated; S5: Using the developed system to comprehensively evaluate the reusability classification of the scrap steel components based on the measured performance parameters, the measured performance parameters including geometric defects, natural vibration characteristics and damage factors, and material strength.
