Improving Design Efficiency, Reliability, and Safe Operation of Trussless Roofing Systems through Mechanics-Based Evaluation of Roof-to-Beam Base Connections
Introduction. Trussless roofing systems employing curved cold-formed metal sheets are widely used in long-span industrial and public structures. Wind uplift and seismic excitation impose significant demands on the roof-to-beam base connection, where stress concentrations, local deformations, and bolt force imb...
