Verification of vinyl sheet piles
The manufacturer of vinyl sheet piles ESP (Everlast Synthetic Products) states that verification of vinyl sheet piles shall be performed for bending and shear. Bending is verified for maximum moment Mmax, shear is verified for maximum shear force Qmax. Internal forces are calculated per unit.
Calculated internal forces can be multiplied by the reduction coefficent of bearing capacity before the verification. This coefficent reflects the degree of uncertainty of determining the theoretical values of the internal forces and brings into the calculation security.
Bending verification:
Bearing capacity for bending is calculated according to formula:
kde: | Mmax | - | maximum value of bending moment |
Mu | - | bending bearing capacity |
The value of bending bearing capacity Mu is determined per unit and given by the manufacturer of profiles.
Utilization of cross-section is calculated according to formula:
Shear verification:
Shear bearing capacity is calculated according to formula:
kde: | Qmax | - | maximum value of shear force |
Qu | - | shear bearing capacity |
The value of shear bearing capacity Qu is determined per unit and given by the manufacturer of profiles.
Utilization of cross-section is calculated according to formula:
The vinyl strength:
The bearing capacities of the profile are given for the material with ultimate tension strength fu = 6300 psi (43,44 MPa). The user can change this value. If the strength is changed by the user, the values of bearing capacities are recalculated in a ratio corresponding to changed value of strength.
