The Objective of this book is to guide structural engineering students and engineering professionals into the process of roof members design and calculations for steel framed buildings. This book covers gravity and lateral loads calculations in accordance with ASCE7-10, how to calculate snow drift loads, moment frames and braced frames lateral load analysis using the slope deflection methods and unit load methods. Moment connections calculations according to AISC Design Guides, and roof members design subjected to both axial and flexural bending. This book also covers over 230 different sections details done in CAD and REVIT for roof framing. Details such as roof beams and joists attachment into a brick and metal studs walls, CMU walls, concrete and wood walls, connections detailing whether it is a moment or shear connection, existing roof joists web and chord reinforcement, and roof trusses section details.
