V15.0 Design Examples The v14.2 Design Examples replaces V14.1 and is keyed to the 14th Edition Steel Construction Manual and the 2010 Specification for Structural Steel Buildings. An introduction to designing steel structures using the AISC Steel. Construction Manual, 13th edition. A Beginner's Guide to the Steel Construction Manual. Structures (a building, a tower, and a truss bridge) that cover most of the bases.
This second edition now addresses seismic and wind applications. It includes design procedures and exam- ples for the four-bolt extended stiffened and unstiffened, as well as the eight-bolt extended stiffened, end-plate moment connections. Users will find that the guide contains a clarified design approach to seismic end-plate connection design compared to the recommenda- tions foun d in FEMA 350. The ba sis for each design recommendation is outlined in detail and presente d as a step-by-step procedure.
Connection limit states are discussed in the guide to help designers understand the principles behind the behavior of extended end-plate moment connections. Addresses all facets of industrial building design and includes a comprehensive section on crane runway design. Part I covers owner-established design criteria, roof systems, roof trusses, wall systems, framing schemes, bracing systems, column anchorage, and service- ability criteria.
Part II concentrates on the complete design of industrial buildings with cranes and addresses fatigue, roof, wall, framing and bracing systems, crane runway girder design, crane runway fab- rication/er ection tolerances, and column design. Stepped column design is also discus sed. A second ed ition of.
An excellent introduction to the con- cepts of torsion in open and closed cross- sections, this design guide facilitates calcu- lations of torsional stresses and establishes a basis for design. For open-sections such as W-shapes, the normal and shear stresses due to both pure and warping torsion can be calculated using the guide.
In addition, channel and Z-shaped open cross-sections are addressed, as well as closed cross-sec- tions such as rectangular and round HSS and steel pipe. Several examples and design curves are included in the guide. Addresses both per- manent and temporary erection bracing, including an important chapter on con- struction phase loads. Topics addressed include column and column base (with extensive discussions of potential failure modes, including fracture of fillet welds between the two, bending failure of base plates, anchor rod rupture, buckling, pull, push-through, and push-out), dis- cussions of tie members, beam to column connections, and diaphragms.
In addi- tion, wire rope diagonal bracing and con- nections are covered, as well as design of deadmen. Contains this information and much more. The guide offers multiple exam- ples for the proper design of transverse stiffeners, web doubler plates and diago- nal stiffeners. Detailed discussions are included on topics such as unreinforced columns, stiffness considerations, force transfer and the economical selection of columns.
Also covered are detailing rec- ommendations for special cases, such as column stiffening for beams of differing depth and beam framing over columns. The appendix includes design recom- mendations for weak-axis moment con- nections, including research findings.
