History, Status, and Problems on Inspection Techniques for Fabrication of Steel Building Structures

Abstract

This paper presents histories, current status, and problems associated with steel fabrication in Japan, with particular emphasis on quality assurance of the products. Inspections employed in various phases of steel construction and qualifications required for engineers and technicians are overviewed, and problems to be resolved for assuring good quality to steel buildings are identified. The following observations and recommendations are notable: participation of industry inspectors for the authorization of fabricators; changes of design and construction procedures in view of reduction of the frequency and time of inspections currently stipulated; reevaluation of precision requirements in light of cost effectiveness; and standardization of welded connection design to avoid wrong designs.
