This lecture covers the design and calculation of structures, focusing on forces at supports, inclined forces, and uneven supports. It also includes topics such as domes, shells, arches, vaults, and cables. The course aims to provide students with the basic skills necessary for understanding load-bearing structures. The instructor emphasizes a global understanding of how structures operate and the importance of stability. The lecture prepares students for a graded exam and provides practical information on test procedures and materials. It also introduces students to various types of loads, such as point loads, distributed loads, and parallel inclined forces with mobile supports.
