a) Design Load = Characteristic Load
b) Design Load = Characteristic Load + Partial factor of safety
c) Design Load = Characteristic Load / Partial factor of safety

d) Design Load = Characteristic Load x Partial factor of safety

Answer: d
Explanation: Design Load = Partial factor of safety x Characteristic Load.
This partial safety factor accounts for possibility of unfavourable deviation of load from characteristic value, inaccurate assessment of load, uncertainty in assessment of effects of load and in assessment of limit state being considered.
