Observations of post-hurricane events indicate that light-frame wood houses are vulnerable to failure due to the inability of their connections to provide sufficient transfer of uplift wind loads from the roof of the house to the foundation. One of these connections is the roof-to-wall connection (RTWC), which connects roof trusses to the top plate members of the walls. This issue has been investigated through full-scale testing at the Insurance Research Lab for Better Homes. This thesis describes the detailed finite element modelling performed for this full-scale testing and provides a comparison of the numerical predictions with the experimental results. The comparison revealed the ability of the sophisticated finite element modelling to predict the nonlinear response of the roof under uplift wind loads that vary both in time and space. A semi-analytical solution for analyzing the full-scale test is also introduced. With the use of statically indeterminate slope deflection equations that include shear deformation, the new model simulates
