One-Way vs Two-Way Slabs: the Difference That Matters

Supports decide how a slab spans - the famous "ratio of 2" rule is only a shortcut for panels supported on all four edges. Where the rule comes from (a one-line stiffness derivation), what EN 1992-1-1 actually says, and how the reinforcement layout changes between the two.

Steel Beam Design to Eurocode 3: Step by Step

The full EN 1993-1-1 check sequence for a laterally restrained steel beam - section classification, plastic bending resistance, shear resistance, moment-shear interaction, and SLS deflection - with a complete worked example on an IPE 300 in S275.

Punching Shear Design of Flat Slabs to EC2

The EN 1992-1-1 clause 6.4 punching check step by step - the basic control perimeter at 2d, the beta factor for moment transfer, the concrete resistance vRd,c, the column-face crushing limit, and sizing shear studs and the outer perimeter - with a full worked example for an interior column.

RC Beam Flexure Design to TCVN 5574:2018

How TCVN 5574:2018 checks the ultimate bending capacity of a rectangular reinforced-concrete section - the rectangular stress block, the relative compression-zone height, the ductility limit (relative boundary height), and singly vs doubly reinforced sections - with a worked example.
