Question

Which load combination satisfies the value of partial safety factor for live loads as 1.05 in case of limit state of strength?

A.

DL+WL/EL

B.

DL+ER

C.

DL+LL+CL

D.

DL+AL+LL

Correct option is C

Partial Safety Factors for Loads

(as per IS 800:2007 – Limit State of Strength)

1. DL + LL + CL

Dead Load (DL): 1.5

Live Load (Leading): 1.5

Live Load (Accompanying): 1.05

2. DL + LL + CL + WL / EL

Dead Load (DL): 1.2

Live Load (Leading): 1.2

Live Load (Accompanying): 1.05

Wind Load / Earthquake Load (WL/EL): 0.6

3. DL + WL / EL

Dead Load (DL): 1.5 (0.9 for stability check)

Wind Load / Earthquake Load (WL/EL): 1.5

4. DL + ER

Dead Load (DL): 1.2 (0.9 for stability check)

Erection Load (ER): 1.2

5. DL + LL + AL

Dead Load (DL): 1.0

Live Load (LL – Leading): 0.35

Live Load (LL – Accompanying): 0.35

Accidental Load (AL): 1.0
