Steel Design
Design of steel members and connections to AISC 360 with ASCE 7 loads: LRFD and ASD, steel grades, shapes and compactness, tension members with net area, shear lag and block shear, columns and the AISC column curve, laterally braced beams with deflection and plastic analysis, lateral-torsional buckling, shear and web local yielding and crippling, beam-columns, bolted and welded connections including eccentric groups, and frame stability, the direct analysis method and bracing, applied to the maintenance bay of a municipal operations center.

What you'll learn
- Explain how steel structures are organized and designed by LRFD and ASD, and compute required strengths with the ASCE 7 load combinations and the AISC 360 resistance factors.
- Select steel grades and rolled shapes, compute elastic and plastic section properties, and classify cross-section elements as compact, noncompact or slender.
- Design tension members for gross yielding, net fracture with shear lag and staggered holes, block shear and slenderness.
- Design columns with effective lengths and the AISC column curve, including slender element limits and the effect of intermediate bracing.
- Select laterally supported beams for flexure, deflection and camber, and use plastic analysis or moment redistribution for continuous beams.
- Compute the lateral-torsional buckling strength of beams with Lp, Lr and the moment gradient factor Cb, and choose bracing that makes beams effective.
- Check webs for shear, coped ends, web yielding and crippling under concentrated loads, and decide when bearing stiffeners or tension field action are needed.
- Design beam-columns with the AISC interaction equations and second-order amplification by B1, checking every governing load combination.
- Design bearing-type and slip-critical bolted connections, including double-angle shear connections and eccentric bolt groups by the elastic and instantaneous center methods.
- Design fillet-welded connections, including balanced welds for angles, size limits and eccentric weld groups, and compare welding with bolting for cost and quality.
- Assess frame stability with the direct analysis method and the amplification factor B2, design tension-only bracing, and size braces for strength and stiffness.
- Design a monorail beam, assemble a member schedule, and review a complete steel building for load paths, stability, constructability, fire and corrosion.
