This paper presents the results of an experimental and numerical investigation into the axial strength of cold-formed thin-walled lipped channel sections with service holes under ambient and uniform high temperature conditions. Short columns of two different thickness with service holes under different temperatures have been tested, and analysed by using a variety of design methods and a commercial finite element program ABAQUS (1998). Three design methods (the British Standard BS5950 Part 5 (1987), Eurocode 3 Part 1.3 (CEN 1996) and the American Specification AISI (1996)) have been used in this paper. In the finite element analysis, both geometrical and material non-linearities are taken into account. The high temperature stress-strain relationships of steel are determined according to Eurocode 3, Part 1.2 (CEN 1995) and Outinen (1999, 2000, 2001). To enable BS5950 Part 5 (1987) and Eurocode 3 Part 1.3 (CEN 1996) to predict the ultimate strength of thin-walled columns with service holes, the AISI (1996) design method is introduced. To extend the capacity of the three design methods to deal with distortional buckling, the method of Young and Hancock (1992) for calculating distortional buckling capacity is introduced in these codes. The ambient temperature design methods for thin-walled columns in BS5950 Part 5 (1987), Eurocode 3 Part 1.3 (CEN 1996) and the AISI specification (1996) are modified to take into account changes in the strength and stiffness of steel at elevated temperatures. It is found that service holes can have a significant effect on the load capacity of a column regardless of the column temperature when thicker members are used. From extensive comparisons between the test results, modified codes' predictions and numerical analyses, it may be concluded that by adopting the aforementioned modifications, the current code design methods are suitable for evaluating the buckling behaviour of perforated short columns at elevated temperatures.

If CADS SWMD is run in conjunction with frame analysis software, then the section properties are imported automatically. The program allows for all permutations of tapered members and those with two, three or four flange haunches. The section properties for positions in the non-uniform parts of haunched and tapered members are calculated by the program during its execution.

A group of holes may be specified and applied to all or part of the member length and an allowance is made for the local increase in design strength available at holed sections due to strain hardening.

The support conditions are defined, and lateral restraints may be applied at the ends of the member and at intermediate positions along its length to prevent buckling. Options include point restraints (supported beam, purlin or bracing) or distributed/continuous restraint (concrete floor slab, sheeting or decking) and are easily defined via an easy to use Windows dialog box.

CADS SWMD divides steel members into potential lateral buckling lengths and provides default values for the effective length factors based upon an interpretation of tables 9 and 10. However, these values may be marked as being subject to de-stabilising loads or edited by the user to accommodate any special conditions or interpretations. As well as EC3, members can be checked for lateral buckling according to BS 5950 section 4, and for torsional buckling to Appendix G of BS 5950 Part 1.

Designers using CADS SWMD in `stand-alone mode may create several combinations of uniform, distributed, point and/or moment load types and the software will perform its own analysis to calculate their effects. For ease of use some or all of the loads may be configured to appear on the main screen display.

Once the calculations have been completed the results summary reports the most critical `utilisation factor for local strength capacity, lateral buckling, torsional buckling and deflection. For more detailed results, full calculation results are easily displayed. Alternatively, the graphical results option displays a diagram of the member showing the support conditions and restraints in plan and elevation with diagrams of axial, shear and moment effects. Designs can be refined quickly by simply selecting an alternative section type, size or changing the lateral restraints and/or details of the haunch.

Provides a comprehensive range of member property and capacity tables in accordance with BS 5950-1:2000. Explanatory notes address dimensions of sections, section properties, and effective section properties.
