The structural design method that DOES NOT take into account the safety factors on the design loads is

1. working stress method.
2. load factor method.
3. ultimate load method.
4. limit state method.

Correct answer: working stress method.

Solution

The working stress method is based on the elastic behavior of materials and uses allowable stress limits without incorporating safety factors for design loads, unlike the other methods which account for uncertainties and safety.
