Design Concept of Steel-Concrete Composite Slab Using an Adhesive

Abstract

A steel-concrete composite slab using an adhesive has been developed in our previous study. The composite system may be designed simply and provide economical advantage compared with conventional systems having mechanical shear connectors. This paper describes a design method for the composite slab conforming to Japanese design code. Effectiveness of the system is discussed from an economic point of view. By employing the composite system, the construction cost of bridge deck can be decreased to 86-94 % of the cost of conventional system.
