NOTES
FOREWORD This spreadsheet performs an analysis and design of simply supported and cantilever, steel beams bending about their X X axis and subjected to gravity loads. Beams can be either with full restraint or without full restraint.
Design is in accordance with BS 5950-1:1990. Bending moments, shear forces and deflections are computed at 1/60th positions along the span and the maximums of these values are used for the design. The equations for the analysis have been obtained from the Reinforced Concrete Designer's Handbook by Reynolds and Steedman. Self weight of the steel section is automatically included in the calculations. The moment capacity of the section is calculated taking into accoun the corresponding shear force and a reduction is made as necessary. A check is made to see if a shear bucking calculation is required and a warning is issued. This spreadsheet also contains a calculation sheet for checking local web bearing and buckling. The spreadsheet uses UK steel section properties which have been directly obtained from the Corus Construction Manual, released on CD in February 2000. The values were imported into Microsoft Excel v8.0 from the html tables contained on the Corus CD. No typing in of values has been carried out and therefore these tables should accurately reflect the tables as published by Corus.
SETUP This spreadsheet has been formatted using Arial, Arial Black, Symbol and Tahoma truetype fonts.

ACCURACY This spreadsheet calculates exact values of bending moment, shear force and deflections at 1/60th positions along the span of the beam. As the actual maximum moment may not occur at precisely one of these positions, a small error in the value of the moment may occur. In a simply supported beam, the shear force should be zero at the point of maximum moment. Where the critical section coincides with the maximum moment, a small value for shear force may be displayed. This occurs because of the small inaccuracy in determining the exact position of the maximum moment. The above inaccuracies are no different than that displayed in software produced by the Steel Construction Institute which employ similar methods of analysis and design. However, these inaccuracies should be viewed in the correct perspective. The fact that the beam is checked and designed at 61 positions along its span clearly indicates a more realistic approach to the actual behaviour of the beam. Consider a beam with a single point load where the maximum moment is at the point of zero shear. According to the code, one would be justified in stating 'low shear'. Yet, just a fraction away from the point of maximum moment, the shea force leaps to its maximum value which could result in 'high shear' and an under designed beam. This spreadsheet, by virtue of checking at 61 positions along the beam, would not be caught out by such mathematical anomalies.
MOMENT CAPACITY Moment capacity is calculated at 1/60th positions along the beam span taking into account the co-existent shear force. If the shear force is determined as 'high', then the corresponding moment capacity is reduced in accordance with code requirements. At each position the 'unity factor' is calculated. This factor is the ratio of the applied moment to the momen capacity. A unity factor of one represents full utilisation of the beam's capacity. A unity factor exceeding one indicates failure. The largest value of the unity factor determines the position of the critical section along the beam.
EFFECTIVE LENGTH Click on the "factor" cell and choose an effective length factor from the drop-down list. If circumstances dictate a factor which is not listed, enter the factor directly into the "factor" cell ignoring the drop-down list. This procedure can be used when considering a portion of beam between a lateral restraint and an end support. Calculate the effective length in accordance with clause 4.3.5 and divide it by the length between the restraint and the end support to obtain an effective length factor for entering into the "factor" cell..
LOCAL WEB BUCKLING AND BEARING Web Slenderness Ratio The effective length of an unstiffened web with the flange restrained is calculated from 2.5d/t (cl. 4.5.2.1). This is based on an effective length of the web equal to 0.7d where d is the depth between fillets. Clear the flange restrained tick box for a flange which is not restrained. This will enable the effective length of the web to be calculated using LE factors obtained from Table 24 of the code.
Support Reaction Tick Box Tick this box when considering the reaction at an end support. Clear the box when considering a point load applied to the top flange of a beam. A point load applied to the top flange will disperse to either side of the stiff bearing length. An end support reaction will disperse to only one side of the stiff bearing length plus a partial dispersal through any overlap of the end of the beam past the stiff bearing length. (see the sketch on the Bearing & Buckling sheet) Note! If a point load is closer to the end of a beam than half the dispersal length (n1 or n2), calculate as if for a support reaction.
Overlap Dimension 'c' This is the dimension between the end of a beam and the stiff bearing length when a beam overlaps the stiff bearing length. (see the sketch on the Bearing & Buckling sheet). If the end of the beam does not overlap the stiff bearing length then c = 0.
TIPS #1 When entering loads. the partial UDL cells can be used for point loads by entering zero in the loaded length cell. #2 To enter project data into a number of sheets simultaneously, hold down the CTRL key and click on the sheet tabs of the relevant sheets. This will 'group' the sheets and data entered into one sheet will be automatically entered into the others. When finished, click on any other sheet tab which has not been selected to release the 'group' selection feature.
