Serviceability load states
Verification of serviceability limit state is based on standard EN 1996-1-1, paragraph 7.2(5). Dimension limits of the masonry walls are checked in accordance with Annex F. Verification of the serviceability limit state uses clear height of the wall, not the effective height.
Following dimensions are used for the verification of the serviceability limit state:
t |
|
h |
|
l |
|
Due to validity limits of the Annex F ,the minimal thickness of the wall is
Walls restrained at the bottom
Walls restrained at the bottom should satisfy following formula:
Walls restrained at the top and bottom
Walls restrained at the top and bottom should satisfy following formula:
Walls restrained at the bottom and stiffened on one vertical edge
The maximal values of h/t ratio for walls restrained at the bottom and stiffened on one vertical edge are shown in following graph:
Limiting values of h/t ratio depending on l/t ratio
