Abstract – Composite walling is a novel building system comprising of two outer skins of profiled steel sheeting infilled with concrete. This paper deals with an experimental investigation to understand the Axial behaviour of a Composite Wall Panel (CWP) which are casted and tested without reinforcing bars using Basalt Fibre reinforced concrete (BFRC). Its development has come about as an extension of the well-known composite system used worldwide. Steel components are relatively thin and prone to buckling, whereas the infill concrete provides restraint against buckling and thermal insulation at high temperatures. Composite wall panels have many advantages, when used in conjunction with composite floor panels and can be used as core walls in steel frame building structure, although they have the potential to be used in load bearing construction. Thus, these panels can serve as an alternative to load carrying brick walls and therefore, low rise buildings can be constructed by using these light weight wall panels.
bond connection is crucial. In the Fig.1 elements of the composite wall are shown. In the present study, the composite wall panel structures, the steel sheeting will act to stabilize the building frame when it is fixed and it provides permanent formwork for the infill concrete. Once the concrete has hardened axial, lateral and inplane loads will be carried out for both the steel and concrete. Finally, the study is to determine the fundamental behaviour of load bearing composite wall panels made of cold formed steel sheet and concrete under the axial load condition.
Key Words: Composite wall panel (CWP), Basalt Fibre Reinforced Concrete (BFRC), Basalt Fibre (BF), Axial Behaviour.
1.INTRODUCTION In the day-by-day emergence of recent trends in construction industry, composite construction method has gained it popularity for its economical usage of materials and providing excellent sustainability than conventional construction system. The composite construction method is a widely used diaphragm strengthening method where two different materials perform a composite wall depends upon shear action between the corrugated steel sheeting on the hardened concrete. Structures made of two or more distinct materials are referred to as composite constructions. Typically, the materials used in structural engineering include concretesteel, plastic-steel and concrete-timber etc. By effectively connecting the two components, composite construction includes the structural characteristics of both materials to create more rigid, stronger and lighter members. In order for the two materials to function as a single unit, their shear-
