This course starts with introduction of structural engineering and brief review of Mechanics of Materials in Architecture I. The mechanical thinking based on the three core elements of mechanics (equilibrium, compatibility, force-deformation relation) is always emphasized through out the course. The main topics include the analysis and design of structural members subjected to torsion, bending and combined forces, analysis of stress and strain, calculation of deflections, and statically indeterminate structures. Specialized topics cover the composite materials members, shear center, elasto―plastic behavior, and classical energy mechanics. Sound knowledge in this course is essential for successful study of the material and structural design courses at the junior and senior levels.
