An overview of the procedures that need to be followed in steel beam design is discussed in this article. There are basic steps to be followed to complete the design. These steps can be categorized into six main subjects according to the BS 5950.


The behavior of cellular beam is described using design methods according to BS: 5950, considering particularly the strength of tee sections and web post element. Such behavior is derived from parametric study involving finite element analysis using software ANSYS. The design method is based on plastic analysis of beam section at ultimate loads and elastic analysis at serviceability loads. The procedure of design of cellular beam is illustrated and an example based on design method is worked out and its verification is done for checking the suitability.


I- shaped steel sections are widely used as main structural element as beam and column in various building structures. It is advantageous to have web perforations, especially in beam elements, to allow for the passage and installation of piping, duct works and electrical conduits without increasing the floor to floor height, resulting in saving in amount of steel used. Such perforations of circular shape are widely used called cellular beam. The presence of web opening requires checking structural adequacy and characteristics. The performance of such beam such as load carrying capacity and failure modes are investigated through design methods and finite element analysis. Such design methods are described in BS: 5950 part 1, part 3.1and SCI publication 100.


To ensure an adequate design, the secondary deflections occurring at the opening should be added to the primary deflections due to overall bending of the beam. The total deflection of the beam is found out by summation of deflection due to shear in tee and web post and bending in tee and web post for each opening. The shear force leads to additional deflections. The maximum deflection should not exceed span/200 for all other beams as per BS: 5950 part 1.


A cellular beam is designed in accordance with BS: 5950. The same beam is analysed using finite element analysis software (ANSYS) and all results are verified. The geometry of cellular beam is modelled and loaded accordingly. The deflection, bending moment, shear force and horizontal force at various sections of beam is calculated theoretically and the observed results from finite element analysis software are presented in tabular form. The variation in results for theoretical and using software ANSYS is less than 5%, this is due to dimensional linearity, material properties and localized effect of three dimensional modelling in ANSYS. Hence the applicability of such code of practice can be observed. Such design method can be applied to various beam sections with different opening ratios and spacing. Web stiffeners can be applied under point loads, near the support for strengthening of beams.


Seventh Edition The first edition of this Design Guide was published in 1985; it was revised in 1987 (2nd Edition), in 1992 (3rd Edition), in 1996 (4th Edition), in 1997 (5th edition) and in 2001 (6th edition). It is a basic working tool for users of BS 5950-1 Structural use of steelwork in building Code of practice for design Rolled and welded sections, which was first published in 1985, revised in 1990 and in 2000.


4.4 Aiming to optimise the flat base of a stiffening rib in a thin central pan of a steel piling sheet, the person skilled in the art would find design recommendations in E3 (British standard BS 5950: Part 5: 1987); the patent relates to piling sheets such as E4 which typically have a gauge between 3 and 8 mm (see paragraphs [0009] and [0014] of the patent specification), i.e. to cold formed sections, and E3 is the code of practice that was applicable to the design of cold formed sections at the priority date of the claimed patent. For the person skilled in the art of designing cold formed steel sections, E3 constituted common general knowledge at the priority date of the patent.
