Abstract
For this study, the effect of lateral loads on the forces in the reentrant corner of structures was examined so as to better understand why damage occurs in this location after major wind or seismic events. Thirty models were analyzed using finite element analysis in SAP2000 with varying dimensions and wall locations. Theses changing parameters were used to see how the axial forces in the reentrant corner also changed accordingly. The models were configured so as to mimic light-framed timber construction. In each case the models were subjected to the same load conditions with the only variation between the models being either the dimensions or locations of walls. The study found that the axial force for the interior and exterior struts acted linearly, as the length of the diaphragm increased so did the axial force. The results for the interior and exterior chord showed that the analog for the diaphragm transition is from a propped cantilever to a simply supported beam as the length of the diaphragm increased. Finally it was also found that the addition of walls, both exterior shear walls and interior shear walls, greatly decreases the axial forces for both the interior and exterior strut and interior and exterior chords in the reentrant corner.
