SITUATION.
A three-story building has interior columns spaced 8-m apart in two perpendicular directions.
Given Design Loads:
Roof DL = 5.0 kPa
Floor DL (typical each floor) = 7.0 kPa
Roof LL = 0
3rd Floor LL = 2.4 kPa
2nd Floor LL = 6.0 kPa
In accordance with NSCP provisions, reduced design floor live
load, L = Lo (0.25+4.57/ VAi)
%3D
where:
Lo = unreduced live load'
Ai = influence area = 4 x tributary area for a column
%3D
%3D
Based on the tributary area of an interior column,
What is the total axial load (kN) on a column at the second floor level due to service LL?
82.3
76.8
164.5
153.6
