| Abstrait: |
In this paper, a method for the pre-design of integral abutment bridges is presented. It is based on the use of common design tools developed for conventional bridges with bearings and joints. The soil-pile-abutment system is hereby replaced by a single rotational spring. Therefore the determination of the spring properties is described in detail. Furthermore the calculation procedure for the moment induced by uniform temperature and for the normal force in the superstructure induced by the restraint moment is presented. As these calculations are not integrated in conventional design tools, simple hand calculation formulas have been developed. Their application is shown via a design example in this paper. |
