Initial design approach for steel framed buildings
Introduction
The successful integration of structure is crucial to solving the aesthetic, functional, technical and economic requirements of a building. These requirements must be addressed during the design process.
Some structural principles related to steel
The main types of force occurring are: Compression (C), Tension (T) Bending (B) Shear (S) and Torsion (To) - these may be resisted by elements and simple systems in various ways.
Systems to give stability under horizontal load
The structural system as a whole must also be capable of maintaining strength, stiffness and stability. These conditions will be satisfied by selection of suitable members and methods of connection, but the building will also require to resist horizontal loads, normally by the general form of the structure, method of connections, or additional bracing elements.
