A Study on the Structural Strength and Behaviour of Composite Profiled Steel Sheet with Plywood

摘要

Shelter, the second basic need of man, has been a preoccupation for many governments all over the world trying to house their growing population. Roof is the covering on the uppermost part of a building. Roof not only provides protection to the buildings from the effects of weather but also plays an important role in architectural and aesthetic point of view. Profiled steel sheet are increasingly used in structural application in recent years. Profiled steel sheet connected to plywood which is known as profiled steel sheeting plywood (PSSPW) system can be used as an alternative to traditional form of roof construction. This study investigated experimentally and analytically the possibility of employing the PSSPW as a roof surface to provide an efficient emergency shelter. The aim of this study to investigate the structural strength and behaviour of composite profiled steel sheet with plywood. The tests were performed on profiled steel sheet and profiled steel sheeting with plywood. The failure loads, failure modes and the load-web deformation behaviour of profiled steel sheeting with plywood are also presented. The experimental and analytical results were compared to validate and determine the structural strength and behavior of profiled steel sheet and composite profiled steel sheet with plywood (PSSPW). This PSSPW composite roofing helps to enhancing the stiffness and strength of the composite system. The proposed PSSPW composite roofing system has a great potential to be exploited for the construction of housing as well as disaster relief shelter. The application of plywood as a load bearing structural component in PSSPW system has the potential to meet the demands of building construction. This system can reduce time and overall cost of construction and has the potential of opening up new composite system in the building construction industry.
