Problem Statement

Slender Column Design in Non-Sway Frame - Moment Magnification Method (ACI 318-19)

01 Sketch Upo 1

Evaluate slenderness effect for columns in a non-sway multistory reinforced concrete frame by determining the adequacy of the square tied column shown below, which is an exterior first floor column. The design forces obtained from a first-order analysis are provided in the design data section below. The story height is 12 ft. it is assumed that the frame is braced sufficiently to prevent relative translation of its joints. Assume 40% of the factored axial load is sustained. Compare the calculated results with the values presented in the Reference and with exact values from spColumn engineering software program from StructurePoint.
