Live Load Element Factors Used in the Reduction of Uniform Live Loads per ASCE 7-10, Table 4-2

April 16, 2018 Abdul Siraj, P.E.

In this post, I will provide a brief overview of the live load element factors,KLL, used in the reduction of uniform live load specified in ASCE 7-10, Table 4-2.

 

Live Load Element Factors, KLL, by Element Type

 

Live load element factor for interior columns, KLL =  4

Live load element factor for exterior columns without cantilever slabs, KLL =  4

Live load element factor for edge columns with cantilever slabs, KLL = 3

Live load element factor for corner columns with cantilever slabs, KLL = 2

Live load element factor for edge beams without cantilever slabs, KLL = 2

Live load element factor for interior beams, KLL = 2

Live load element factor for edge beams with cantilever slabs, KLL = 1

Live load element factor for cantilever beams, KLL = 1

Live load element factor for one-way slabs , KLL = 1

Live load element factor for two-way slabs, KLL = 1

Live load element factor for members without provisions for continuous shear transfer normal to their span, KLL = 1

Live load element factor for all other members not identified, KLL = 1
