Answer 1

Explanation:

Characteristics Load

It is assumed that in ninety-five percent of cases, the characteristic loads will not be exceeded during the life of the structures. However, structures are subjected to overloading also.

Characteristics load is computed from statistical data of the graph shown below:

Structures should be designed with loads obtained by multiplying the characteristic loads with suitable factors of safety depending on the nature of loads or their combinations, and the limit state being considered.
These factors of safety for loads are termed partial safety factors (γf) for loads. Thus, the design loads are calculated as
Design Load (Ld) = Characteristics Load (Lc) × Partial factor of safety (γf)
