Lecture
This lecture discusses the structural behavior of arcs on multiple bays, focusing on the compression and tension forces exerted on spherical domes and vaults. The instructor explains the support forces, variations in arcs-and-cables, and the design considerations for gothic arches. The presentation includes a case study on the Eads Bridge construction, highlighting the placement of supports and the distribution of loads. Various design concepts and materials for structural courses are also covered, emphasizing the critical role of supports in maintaining stability and equilibrium.
