Problem. The PIER tool produces the total section forces at the base of a column or wall. Under a horizontal load the base shear and the overturning moment are compared.
Reference document. Static equilibrium is used.
Under a horizontal load the base shear and the overturning moment take these values from statics.
Numerical model. The method is free-body equilibrium.
Cantilever wall, horizontal load at the top
Parameters. H = 100 · h = 10
Closed form. Static equilibrium
| Quantity | Reference | Computed | Deviation |
|---|---|---|---|
| Base shear force | 100 | 100 | 0% |
| Overturning moment at the base | 1,000 | 1,000 | 0% |
