Roofing sheets systems for industrial sheds in cyclone prone areas based on dynamic testing

Rooing sheets of industrial sheds have been observed to fail in uplift under extreme wind conditions as in a cyclone. The ultimate loads from full scale static uplift load tests on asbestos cement and galvanized iron corrugated rooing sheet systems with different connections for span/purlin spacing...
