Effects of roof geometry on tornado-induced structural actions of a low-rise building

•Tornado-induced loads on building frames are more intense than overall loads.•Flat-roof building experiences significantly higher moments than gable and hip roofs.•Gable-roof building experiences lower shears than flat and hip roofs.•Hip-roof building experiences lower uplift than flat and gable roofs.•ASCE7-16 under-predicts tornado-induced uplifts and moments on low-rise buildings.
