The programs in this section provide analysis and design for structural elements made of steel.

 

Code References

 

Program modules for STEEL design are designed to be in conformance with the AISC 9th Edition Allowable Stress Design and AISC Third Edition LRFD Design.

 

Limited load combinations supported are:

 

Allowable Stress Design: ASCE 7 Section 2.4.1, IBC 2003 Section 1605.3.1, 2003 NFPA 5000 Section 35.15.1 (which ties back to ASCE 2.4.1) and 1997 UBC Section 1612.3.2.

 

Load & Resistance Factor Design : ASCE 7 Section 2.3.2,  IBC 2003 Section 1605.2.1, 2003 NFPA 5000 Section 35.15.1 (which ties back to ASCE 2.3.2) and 1997 UBC Section 1612.2.1.

 

 

Multi Span Steel Beam

Multi Span Steel Beam allows design of up to eight spans on one calculation sheet. All spans can be simply supported with optional cantilevers or can be continuous over supports with optional cantilevers and end fixities. Dead and live point, moment, and uniform/trapezoidal loads can be applied. Alternate span live loading is easily defined. Code stress checks are performed for W, S, H, M, C, MC, T, P, L, LL, WT, ST, and MT sections, including provisions for thin compression elements and details of Appendix C. Reactions, shears, moments, deflections, and stresses are given.

 

Steel Beam Analysis & Design

Steel Beam Analysis & Design supplies more extensive design ability than the multi-span program. Up to 26 point, moment, and uniform/trapezoidal loads may be applied, minor axis bending, secondary members, duration of load factors, and optimal section selection is available.

 

Torsional Analysis of Steel Beams

Torsional Analysis of Steel Beams can fully analyze and section beams subjected to distributed and point eccentric loads, bending moments, and twisting moments. The beam can have pin/pin or fix/fix torsional and bending fixity conditions, and all results use new procedures for rotation and stress calculations. Of course, full AISC allowable stresses are calculated based on slenderness, bracing, and moment variations.

 

Steel Biaxial Column Design

Steel Biaxial Column Design includes all the beam analysis capabilities of our Steel Beam program, simultaneously about both axes, and combined with eccentric axial loads. Support fixity, unbraced lengths, side sway, effective length factors, and live/short term load combinations are all included in the evaluation of AISC combined stress equations H1-1, H1-2, and H1-3.

 

Composite Steel Beam

Composite Steel Beam provides detailed analysis of steel sections anchored to a concrete slab. Among the many items considered are solid slabs, slab over formed metal deck, partial composite action, and center/edge slab location. Concrete density, stud capacity, bottom flange cover plate, and effective slab width can also be specified. Loads may be point, uniform, or trapezoidal, and are divided into dead, construction, and live types. In addition to full stress evaluation, shear connector spacings, reactions, and load case deflections are given.

 

Steel Base Plate Design

Steel Base Plate Design allows you to design or analyze a square steel column base plate subjected to axial loads and bending moments. This program allows up to five designs per sheet and access to our extensive steel section databases. Number of bolts, area, capacity, location, support pier dimensions, concrete strength, and duration of load factors are all considered in generating the interaction equations determining stresses within the plates.

 

Bolt Group Analysis

Bolt Group Analysis distributes direct and torsional in-plane loads on a bolt group with up to 16 bolts to find the maximum load on each bolt.
