Non-destructive Testing Quality Control Analysis of Steel Structures in Large-Span Space Buildings
With the continuous development of construction engineering,the number of large-span space buildings is increasing,and steel structures are widely used in span space buildings due to their advantages such as convenient construction.This paper takes the steel structure of large-span space building as an example,analyzes the characteristics of steel structure of large-span space building,and studies four non-destructive testing quality control methods of ultrasonic flaw detection,magnetic particle testing,radiographic testing and penetrant testing,and finally the development trend of non-destructive testing of steel structure of large-span space building,so as to provide an important guarantee for the safety and stability of the steel structure of large-span space buildings.
