Question

There are four secondary drainage outlets

The Secondary drainage depth = 2.5 inch

Rainfall intensity = 3 in/hr

Diameter of the drainage pipe = 6 inch

The projected loading is given below:

Roof Dead Load = 20 psf

Roof Live Load = 18 psf

Wind Load = negligible

Snow Load = AISC recommendation apply

Assume any missing data. Determine the axial load on the marked column considering live load reduction factor.

A single storied general official building is to be located at 200 Inverness Dr West, Englewood, CO 80112 p-p-p-p 6-30 Beam @10 ft ce Beam@10 ft ce Column a10 tcc 40ft Plan view of the lower part

Answer 1

Show the plan view of the roof framing as below. 50 feet 60 feet Roof dead load is 20psf. Roof live load is 18psf Snow load is to be taken as 30psf (AISC recommended for the given location).

60 Slab is two way. The ratio of length to width of slab is-= 1.2 < 2 . Tributary area for column 24 is 10 ft × 10 ft = 100 ft2 Interior column has Ku value of 4. The value of K1,A- 400ft Live load reduction is required, if value of KLLA is more than or equal to 400 ft L=L| 0.25 + L-L,(0.25+7A154) KiLAT = 18 psf| 025+-15 -18 psf Axial load on the marked column is (20 + 1 8 + 30) psf × 400 ft 2-27, 2001b.
