Steel Structure Design Methods ?
What are Methods of Steel Structure Design? There are three different methods for design of steel structure, i.e. simple design, continuous design and semi-continuous steel design 1. Simple Design is the most traditional approach and is still commonly used. It is assumed that no moment is transferred from one connected member to another, except for the nominal moments which arise as a result of eccentricity at joints. The resistance of the structure to lateral loads and sway is usually ensured by the provision of bracing or, in some multi-storey buildings, by concrete cores. 2. Continuous Design In continuous design, it is assumed that joints are rigid and transfer moment between members. The stability of the frame against sway is by frame action (i.e. by bending of beams and columns). The connections between members must have different characteristics depending on whether the design method for the frame is elastic or plastic. The joint must be able t...
