Novel sandwich composite structures

Abstract

Sandwich composite structure is gaining ground in wide scope of applications. If a structure is potentially subject to significant bending moment, cyclic loading and large impact loading arising from hazardous environment, the proposed steel-concrete-steel sandwich system serves as an appealing alternative to existing stiffened steel plate structures. This paper describes the research and development work on a novel sandwich composite structure system which can be utilized in civil and offshore engineering. Various aspects are discussed. These include new mechanical shear connector and/or chemical methods to ensure the composite act between steel face plates and concrete core, lightweight or high strength concrete tailored for different applications.
