You have six chapters open, three cross-references flagged, and a beam-column joint detail due before the next submittal — and ACI 318-25 scatters the provisions you need across every one of them. Scattered provisions produce missed limit states, unconservative details, and plan review rejections that cost weeks. This book maps every design task in ACI 318-25 from the member chapter entry point through the linked utility, materials, detailing, and seismic provisions — so you trace the full code path before the first calculation hits paper. Inside these pages: • Section-Trace System — a five-part navigation tool at every design topic, linking member chapters to the utility, materials, and detailing provisions they reference • Step-by-Step worked examples — flexure, shear, torsion, axial interaction, punching shear, and development length in plain narrative prose • Code-change mapping — refined shear equations, modified hooked and headed bar development, new breakout factors, and seismic shear wall relief tracked from ACI 318-19 to ACI 318-25 • Seismic detailing decoded — special moment frames, special structural walls, boundary elements, capacity-based shear, and the strong-column-weak-beam hierarchy through Chapter 18 • Anchorage design clarified — every tension and shear failure mode for cast-in, mechanical, and adhesive anchors with the updated ACI 318-25 breakout reduction factors • Three new appendices explained — nonlinear response history analysis, performance-based wind design, and sustainability • Section-Trace Master Index — every provision chain consolidated by member type, design task, and code section number in one back-of-book reference Written for practicing structural engineers, PE and SE candidates, plan reviewers, building officials, and graduate students designing to ACI 318-25.
