Finally, the chapter ends by describing methods used, in the present study, to represent the charts of the effective length factor of column in sway or non-sway frames in a computer code. In this, the discussion is extended to cover the strength, stability and serviceability requirements of the British code of practice BS 5950: Part.

Accordingly, ultimate limit state design documents of structural elements are described. Then, determination of loads, load factors, and load combinations are given as requested by the British codes of practice BS 699.

starts with definitions of basic limit-states terminology. Firstly, the forces acting on the structural members and joints are determined by conducting a structural system analysis, and, secondly, the sizes of various structuralĢ Design Procedure for Steel Frame Structures according to BS members and details of the structural joints are selected by checing against specification member-capacity formulae. There is, therefore, a fundamental two-stage process in the design operation. After that, critical loading patterns must be determined to suit the purpose of the building. Attention is then given to the way in which loads are to be resisted. Once the decision has been taen to construct a particular building, a suitable structural system must be selected. As such, it is regarded more as an aid to design, which includes allowable stress levels, member capacities, design formulae and recommendations for good practice, rather than a manual or textboo on design. A code of practice may therefore be regarded as a consensus of what is considered acceptable at the time it was written, containing a balance between accepted practice and recent research presented in such a way that the information should be of immediate use to the design engineer. 1 II DESIGN PROCEDURE FOR STEE FRAME STRUCTURES ACCORDING TO BS Introduction Structural design is grossly abbreviated name of an operation, which for major projects may involve the nowledge of hundreds of experts from a variety of disciplines.
