Title: A Probability-Based Structural Code*

Abstract:A framework for structural codes is introduced in which probability is used to enhance realism and improve consistency in the code treatment of uncertainty of both the measurable and the "professional" kinds. The format is simple and familiar in use and appearance. The theoretical basis depends solely on predicted values (means) and on familiar measures of dispersion (standard deviations or coefficients of variation) ; it is therefore easily grasped. Through the use of coefficients of variation to describe professional uncertainties (workmanship, simplified analyses, loading assumptions, etc.) the flexibility of partial safety factors is obtained without their theoretical inconsistencies. Examples compare the proposed framework to the present ACI Code.
