EN 1996-1-1 - Gravity Wall

The masonry is verified for the load caused by the combination of the compressive normal force and the bending moment and for the load due to the shear force.

Verification of compression bearing capacity

Chapter 6.1.2.1

where:

NEd

-

design value of normal force

NRd

-

compression bearing capacity

Ac

-

compressed area of cross section

fk

-

characteristic value of compressive strength of masonry

γM

-

partial factor of masonry

b

-

width of cross section

h

-

height of cross section

e

-

excentricity of normal force

MEd

-

design value of bending moment

Interaction diagram N-M

Usage ratio of concrete cross-section subject to the combination of bending moment and normal force is determined as |0L| / |0R1| or |1L| / |1R2|. Where L is load, R1 is strength with prescribed excentricity and R2 is strength with prescribed normal force.

Verification of shear bearing capacity

Chapter 6.2

where:

VEd

-

design value of shear force

VRd

-

shear bearing capacity

fvk

-

characteristic value of shear strength of masonry

fvko

-

charakteristic value of original shear strength of masonry

fb

-
