Investigation on wind resistance evalualtion method of composite sidings with metal

For the determination of wind resistance of cladding materials, tests with specimens whose size is relatively small and represents a part of the cladding system, using simplified test setups (i.e., a partial component test) tend to be performed due to their simplicity and the technical testing capability of cladding manufacturers. However, the differences between failure load (pressure) of claddings obtained by such simplified methods and that obtained under more realistic loading with specimens fully representing actual cladding systems (i.e., a complete component test) are not generally quantified. The present study examines this difference in failure loads by performing complete component tests and partial component tests using a wall system employing composite siding with metal, and discusses the parameters which influence failure loads.
