To fulfill the requirements of considering "Adverse" and "Beneficial" loadings required in code section 2.4.3.1, RAM Concept uses pattern loading factors. For dead loadings, RAM Concept uses pattern factors of 1.0 and 1.0/1.4, or 0.71. For live loadings, RAM Concept uses Pattern factors of 1.0 and 0. See "About load pattern" for further information.

The applied dead load pattern factors have the side effect that the self-weight is patterned in the Initial Service LC which can cause conservative calculations for the Initial Service Design. If problems are experienced with this design, a separate model and investigation can be used without the dead load pattern factors to investigate the Initial Service Design.
