This tab covers the Analysis Options for Eriksson Pile.
General Options
Header | Description |
---|---|
Effective Length Factor, k | effective length factor for piles/columns. |
EI Multiplier | Member stiffness multiplier. |
Slenderness Method | Chooses which method will be used to calculate slenderness in the member. ACI uses LRFD 9th Ed. 5.6.4.3, where Secant uses the secant method as described in the ACI Journal, Arthur R. Anderson and Saad E. MOUSTAFA, “Ultimate Strength of Prestressed Concrete Piles and Columns” |
Part of Seismic Resisting System | Is the pile part of the seismic resisting system. Spiral provisions vary depending on whether the pile is part of the structure’s seismic-force-resisting system. |
Resistance Factors
Header | Description |
---|---|
Shear, ϕshear | The resistance factor for shear. |
Flexure, ϕFlex | The resistance factor for flexure. |
Compression, ϕComp | The resistance factor for compression. |
Service Stresses
These are multipliers that return service stress limits.
These multipliers are based on ksi values.
Compression Multipliers
Header | Description |
---|---|
Sustained | Compression multiplier for sustained loads limit. The allowable load is found by multiplying the given multiplier by fc |
Transfer | Compression multiplier for transfer stress limit. The allowable stress is found by multiplying the given multiplier by fci |
Sustained + Transient | Compression multiplier for sustained + transient loads limit. The allowable load is found by multiplying the given multiplier by fc |
Tension Multipliers
Header | Description |
---|---|
Sustained | Tension multiplier for sustained loads limit. The allowable load is found by multiplying the given multiplier by √fc |
Transfer | Tension multiplier for transfer stress limit. The allowable stress is found by multiplying the given multiplier by √fci |
Sustained + Transient | Tension multiplier for sustained + transient loads limit. The allowable load is found by multiplying the given multiplier by √fc |
