Timber Column Design

EN 1995-1-1 (EC5) §6.3 solid and glulam column calculator. Compression, combined bending+compression, biaxial buckling, slenderness, and bearing checks for rectangular and circular sections.

Scope note:
EC5 §6.3 checks for columns. Verify effective length factors, connection details and fire resistance (EC5 Part 1-2) separately.

Column Section & Material

Timber grade and cross-section dimensions.

Section
