What is the partial safety factor for dead load in combination of DL+ WL/EL for limit state of serviceability, where DL=Dead load,WL=wind load, EL=earthquake load ?(a) 1.0(b) 1.5(c) 1.2(d) 0.8This question was addressed to me in an interview for internship.My question is from Determination of Wind Loads & Load Combinations topic in division Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer»

Correct CHOICE is (a) 1.0

To ELABORATE: For limit state of SERVICEABILITY, the load combination is 1.0(DL +WL/EL), for limit state of STRENGTH, the load combination is 1.5(DL +WL/EL), where DL=Dead load,WL=wind load, EL=earthquake load.
