Numerical Assessment Of Roof Panel Uplift Capacity Under Wind Load, Weixian He

Electronic Thesis and Dissertation Repository

ABSTRACT

The integrity of the roof system is essential for ensuring the safety of inhabitants and preventing excessive damage to light-frame wood structures. The uplift capacity of fastened roof panels has been investigated using experimental tests and numerical models, where monotonic uniform static pressures are often applied to the roof panel models. The verification is needed for the adequacy of using static uniformly distributed pressure representing the wind load. Moreover, the uncertainty of nail withdrawal behaviour has not been included in existing numerical models, and the effect due to construction errors has not been addressed rationally.

Response Of A Two-Story Residential House Under Realistic Fluctuating Wind Loads, Murray J. Morrison

Electronic Thesis and Dissertation Repository

Severe wind storms such as tropical cyclones, tornados, downbursts etc. can cause significant damage to infrastructure. Damage surveys following these events have shown that the roofs of residential, wood-frame construction are particularly vulnerable to failures. While damage surveys provide detail information of what components fail, they cannot provide the loads at which these failures occurred or how they initiated. Wind tunnel pressure models provide detailed information of the wind loads on buildings, however, they are not able to predict failures or how these loads are transferred through the structure. In order to better understand the response of wood framed houses …
