Design of short Columns
Transcribed Image Text:OBJECTIVE:
Design the exterior rectangular column with the given loads. Determine the appropriate dimension in the
short direction. Find the required number of 32-mm longitudinal reinforcement bars. Specify the required
spacing of 10-mm ties in mm.
Transcribed Image Text:SITUATION:
The two-story building is analyzed against the gravity loads as shown in the figure below and it is determined
that the exterior column has the following loading:
Pdead = 987 kN
Plive = 1481 kN
Mdead = 220 kN - m
Mlive = 315 kN - m
The maximum dimension allowed due to architectural considerations is 625mm. Concrete strength is 28 MPa
and reinforcement yield strength is 420 MPa. Bending is about the strong axis.
