16.3 Connections to Foundations
(b) Any calculated tensile force across the interface
(a) Base of structural steel section shall be designed to transfer the total factored forces from the entire composite member to the foundation.
(b) Base of structural steel section shall be designed to transfer the factored forces from the steel core only, and the remainder of the total factored forces shall be transferred to the foundation by compression in the concrete and by reinforcement.
|ϕSn ≥ U||(188.8.131.52)|
where Sn is the nominal flexural, shear, axial, torsional, or bearing strength of the connection.
(a) Dowels shall not be larger than No. 11
(b) Dowels shall extend into supported member at least the greater of the development length of the longitudinal bars in compression, ℓdc, and the compression lap splice length of the dowels, ℓsc
(c) Dowels shall extend into the footing at least ℓdc of the dowels
