The structural engineering is an essential component of Architecture. The creativity and imagination of an architect come to reality by adopting a suitable structural system. Architects should understand the basic principles and concepts of structure in order to apply the structural system suitably. The course is designed to explain structural concepts clearly, using examples. The mathematical part of the course is formulated to establish a logical understanding of structural behavior, by passing the complexity of calculations. structural systems like a truss, space frame, plates, shell, tensile structure ?etc will be discussed. The conceptual development of the structural system will be explained with examples, case studies and possible architectural applications in contemporary architecture.
