Dead load:
Dead loads are weight of materials. Mimimum design dead load can be find in ASCE 7 Table C3-1.

Live load:
Live loads are based on function of use. Mimimum design live load can be find in ASCE 7 Table 4-1 or IBC Table 1607.1.
Examples:Office building:
Partition load: 15 psf
Live load reduction:
Floor live load reduction: (ASCE 7-05/10, IBC 2006/2009/2012)
For live load not exceeding 100 psf, not in passenger garages, not in assembly uses, with KLL x AT more than 400 square ft2, Live load can be reduced by the following equation
Lo is unreduced live load, AT is tributary area.
Example 1: Floor live load reduction
Alternate floor live load reduction: (IBC)
For live load not exceeding 100 psf, not in passenger garages, not in group A occupancies of IBC, supporting more than 150 square ft2, Live load can be reduced by the following percent.
R = 0.08*(A-150)
A is tributary area
R is percent of reduction shall not be more than 40 percent for horzontal member, and 60 percent for vertical member, and not exeeding
R = 23.1 (1+D/Lo)
D is floor ded load:
Example 2: Alternate live load reduction
Roof live load reduction:
Roof live load may be reduced by the following equation:
Lr = Lo R1 R2
Where Lr shall not be less than 12 psf and not more than 20 psf
F is number of inches of rise per foot.
Example 3: Roof live load reducton:
Handrails, Guardrail systems, and grab bar:
Handrail: 200 lbs concentrated load in any direction, any point.
Guardrail: 50 lb/ft uniform load and 200 lbs concentrated load at top. 50 lbs in 1 ft square area for intermediated rails, panel filers, etc.
Grab bar: 250 lbs concentrated load in any direction, any point.
Vehicle Barrier System:
6000 lbs concerated load in an 1 square foot area at 1 ft 6 inches above floor or ramp surface.
Fixed ladder: 300 lbs concentrated load in any direction.
Crane wheel loads:
Maximum Crane wheel oad shall be the sum of weight of bridge, crane load capacity, and weight of trolley with trolley in a position that produces maximum load
Design oad increase for crane wheel load:
Vertical impact force:
Lateral force: 20%
Longitudinal force: 10%
