SAFE: Learn Advanced Flat Slab Design with Autocad Detailing

Learn how to determine the preliminary thickness of flat slabs (minimum 125 mm) using span to depth ratios, deflection criteria, and drops, with emphasis on long-span checks and edge beams.

Design drop panels for a flat slab–beam–column system, with edge beams and openings. Apply code rules for rectangular drops, one-third spans, center-line placement, and l by d ratios.

Explore column capitals and edge beams in flat slabs, apply the 90-degree cone from the centerline within column limits and column head outlines, and note excess portions are wasted.

Model and define materials for flat slab in Safe, selecting 456-2000, set design preferences, create nonuniform Cartesian grids, and define concrete M20, FP 500 rebars, slabs, beams, and columns.

Model a flat slab in Safe by defining columns, edge beams, slabs, and drops. Use snapping, offsets, replicate, and 3D view to arrange components accurately and visualize the design.

Apply dead and live loads to flat slabs in Safe, using load patterns, floor finishes, plaster, wall and partition loads, and add area loads with null beams.

Create service and ultimate load combinations, perform pre-analysis checks, and assess deflection, sfd, and bmd for flat slabs using es 456 table 18, while refining mesh and optimizing thickness.

Compare flat plate, flat slab with drops, and flat slab with edge beams, evaluating deflection and punching shear under temperature loads using trial-and-error optimization.

Learn to perform long-term deflection checks for flat slabs, accounting for cracked sections, creep, shrinkage, and temperature effects with new load combinations to ensure safety and economy.
