Verification According to the Safety Factor
Check for bending and stress caused by normal force
The normal stress checking is based on the following expression:
where: | σn | - | normal stress caused by tension or compression |
σm | - | bending stress | |
fn | - | tensile resp. compressive strength of timber | |
fm | - | bending strength of timber | |
SFs | safety factor for bearing capacity of timber cross-section |
The value of utilization is provided by:
Check for shear
The shear stress τ checking is based on the following expression:
where: | fv | - | shear strength of timber |
The value of utilization is provided by:
