Topics in this course include demographic analysis, housing design, site planning, public relations and the municipal approval process. Particular attention is paid to the physical structure of residential properties and the management of the construction process.
Introduction to Architectural and Structural Design
The course provides students with the basic knowledge of structural analysis and design for buildings and other structures. Students will investigate the behavior of structural systems and elements through design exercises, case studies and load testing of models. Students will design structures using timber, masonry, steel, concrete and fiber reinforced polymer (FRP) materials.
