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 the 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 | - | characteristic value of the original shear strength of masonry | |
fb | - | compressive strength of masonry unit |
