Unreinforced Masonry Wall Design

EN 1996-1-1 (EC6) §6.1 unreinforced masonry wall design under vertical load, eccentricity and out-of-plane lateral loading. Full capacity reduction factor Φ calculation with mid-height slenderness effects.

EN 1996-1-1 §6.1Φ at top/mid/base OOP wind pressureNo-tension analysis

Scope note:
EC6 §6.1 checks. No tensile resistance assumed. Verify cavity wall ties, movement joints and lintel bearing separately.
