Publication of “AIJ Recommendations for Structural Design of Steel-concrete Shear Connections”

Abstract

In steel-concrete composite structures, the connectors that join dissimilar materials, dissimilar structural members and systems are important structural elements. Fundamental force transfer mechanism and resistance mechanisms in connectors include bonding, friction, and mechanical shear connections. Whereas heretofore mechanical shear connectors, consisting mainly of headed studs, have been commonly employed in the building structures, in view of the trend toward the diversification of composite structures, it will be necessary to introduce also high-strength and high-rigidity mechanical shear connectors such as perfobond strips, which are used in the civil engineering structures, into the construction field going forward. The “Recommendations for Structural Design of Steel-Concrete Shear Connections” published this time lay forth a structural performance evaluation method for headed studs and perfobond strips in line with joint details in the building structures.
