AIJ-2017 Design Standard For Steel Structures based on Allowable Stress Concept (2005 edition)

AIJ Design Standard (AIJ-ASD 05) is issued by the Architectural Institute of Japan (AIJ). Since 1981, the building regulations have comprised a two-level design procedure, requiring allowable stress design for moderate earthquake loads and ultimate strength design for severe earthquake loads. The AIJ documents stand independent of the building regulations. The Design Standard for Steel Structures — Based on Allowable Stress Concept, along with the Recommendations for the Plastic Design of Steel Structures and Recommendation for Limit State Design of Steel Structures (the full name of 2005 version) owes significantly to the Specification for the Design, Fabrication and Erection of Structural Steel for Buildings published by the American Institute of Steel Construction (AISC), in particular the 1963 and 1967 editions.
