ABSTRACT
The objective of this paper is to evaluate the effect of quality of concrete and construction workmanship on the reliability of bridge structures. The analysis is performed for reinforced concrete T-beams and prestressed concrete AASHTO Type girders. It is assumed that the level of workmanship can be expressed in terms resistance parameters such as bias factor and coefficient of variation. The calculated reliability indices indicate that bias factor is the most critical parameter that determines the structural performance.
