The work of the pioneers of reinforced concrete design was directed primarily towards predicting the strength of members. Ultimate load design is, therefore, not a recent development. In principle it is older than the straight-line theory. The fundamental concepts in ultimate load design of reinforced concrete members are discussed with particular emphasis on the basic assumptions involved, and most common design equations are presented. It is pointed out that a desirable structure does not necessarily result from truly balanced design, which ia characterized by several modes of failure being equally probable. The view is advanced that particularly. undesirable model of failure, such as those having a brittle nature, should be made less probable than modes of failure associated with ductility and warning of distress.
