Wind Load on Roof Structures and Mechanism of Wind-induced Damages

With the development of architectural technique and its construction, a number of roof structures with new types, large spans and high flexibility have been emerged. wind loads become important to these structures. Through a review of the results of wind tunnel tests and post-disaster investigations, wind pressures distribution over roof structures with various types are studied in this paper. Wind pressure coefficients, which are helpful to design and research are given. Wind loads on roof structures and mechanism of wind-induced damage are described in detail. Finally, significant conclusions are obtained for roof structures design.
