Regarded as a "must have" design aid for engineers, designers, fabricators and other specifiers of structural steel, the Design Capacity Tables for Structural Steel (DCT) provides information for the design and detailing of structural steel members and connections. Data is presented in the limit states format of AS 4100. Volume 1 of the DCT contains information on the readily available range of "open" structural steel sections (WB,WC, UB, UC, PFC, TFC, TFB, EA & UA). Also included are BHP Grade 300PLUSTM, the new "Lean Beams", and incorporation of Amendments 1 and 2 to AS 4100. Significant enhancements have been made to the second edition, including improved table layout and easy to read design curves. Data in the DCT includes: dimensions and section properties; design section capacities; values for fire design; and design capacities for members subject to bending, shear, bearing, axial compression, axial tension and combined actions. Also included are design capacities for bolts, welds and floor plates; elastic buckling loads; detailing parameters; section properties for gantry girders and rails; and useful tables for angles subjects to flexural loadings about their rectangular axes (restrained and unrestrained) and angles in trusses. Volume 2 of the DCT (DCTv2ed2) provides up-to-date information on the full range of Australian manufactured hollow sections complying with AS 1163. Additionally, the 1998 version of AS 4100 included some significant changes to the hollow section design provisions. These changes have also been incorporated in DCTv2ed2. Other features of DCTv2ed2 include tables associated with section properties, surface areas, telescoping sections, maximum design loads for simply supported beams with full lateral restraint, design section moment (including torsion) and web capacities, design moment capacities for members without full lateral restraint and design member capacities in axial compression/tension. The text includes data used to generate the tables, information relevant to common applications, useful examples and noting of clauses/equations in AS 4100 which are specific to hollow sections.
