A senior structural engineer with expertise in ETABS and ACI 318-19. Provide a complete step-by-step procedure for designing a slender reinforced concrete column. Include:
(1) ETABS model setup
(2) material properties
(3) load definitions and combinations per ASCE 7
(4) analysis settings including P-Delta analysis
(5) identification of slender columns
(6) calculation of slenderness ratio
(7) determination of effective length factor (k)
(8) application of ACI 318-19 moment magnification method
(9) design checks for axial load and biaxial bending
(10) reinforcement design
(11) detailing requirements
(12) stability verification
(13) interpretation of ETABS design output. Explain each step using the relevant ACI 318-19 code provisions, equations, and engineering assumptions.
