Steel structure building pros and cons
Jul 21, 2016

Analysis, steel structure engineering quality problems
There are many reasons it is difficult to guarantee the quality of steel structure engineering, also very complex, both problems caused by improper, there are also the problems caused by violation of operation, there are problems due to construction personnel skills and responsibility, as well as quality problems caused by the mistakes committed by policy-makers.
(A) the steel itself problems
A units in processing a building 1200*1200*60 of box shaped column Shi, in Shi welding process in the suddenly found 60mm as abdominal Board of thick Board appeared has tear phenomenon, eye visible clear of crack put Board from thickness direction into two half, after NDT detection found crack depth occurred in depth 3mm around, while on same type with a, of addition several Zhang Board cutting of parts for detection, found Board within exists sandwich, rolling quality bad is caused quality problem of main reasons. Welding in the welding process the welding stress of interlayer material away. Hence the phenomenon of plate thickness tear.
