Introduction and Development of Structural Reliability Approach for Cranes

Abstract

Japanese mandatory structural design regulations for fixed and mobile cranes are based on the allowable stress design approach. However, ISO8686, the international standard concerning the loads and load combinations for cranes, provides an option to adopt the limit state design approach instead of the allowable stress design approach. This paper describes an outline of the limit state design method stated in ISO8686-1 and ISO8686-2.
