SETTLEMENT-INDUCED FORCES IN CONCRETE BRIDGES

This paper presents a mathematical model for evaluation of differential settlement-induced forces in non-prestressed continuous concrete bridges taking into account the effects of creep, stress relaxation, and time rate of settlement. A force induction factor is derived by which the elastic solution of settlement-induced forces should be multiplied to obtain the viscoelastic solution. A mathematical model is developed for ease of computation and is applied to two numerical examples. The results of these examples, and others not presented for lack of space, show clearly the necessity of including the time rate of settlement of different supports in the computation of settlement-induced forces.
