A wind tunnel experimental study for low-rise buildings with intermediate roof slope was performed in a simulated open terrain exposure to examine wind-induced structural force characteristics on main wind force-resisting systems (MWFRS). Results show that for rectangular hip-roofed models, the horizontal aspect ratio effects on peak building bay forces and frame bending moments are minimal. However, for vertical bay forces and bending moments around z-axis on end frame members, roof shape (gable/hip) effects are considerable. In particular, 50% larger vertical suctions act on building bays with the gable roof and more than two times larger in-plane bending moments appear at the knee of the gable-roofed end column. The building plan mainly influences the variation trends of horizontal bay thrusts and in-plane frame bending moments of L-shaped hip-roofed building for 0^o–120^o wind directions, compared with those with rectangular building plan views.
