Abstract
A modern conceptual design of a bridge structure should be open to wider criteria, which assure that the structure is endowed with static, dynamic, and ductile characteristics sufficient to tackle the seismic events. Correct conception of the structural morphology, other than the achievement of better guarantees with regard to the seismic behavior, may also lead to economic advantages either in the realization of the whole structural system or in the adoption of seismic devices, with a consequent possible reduction of the management cost of the structure as well. For the satisfaction of these requirements and for the exploration and the verification of innovative structural schemes, refined and subtle analysis formulations and tools must be considered. Such a kind of structural scheme is based on the two-blade slender bridge piers. These are elements subdivided into two parts with different geometric and mechanical properties. The first part has a box section, which is highly stiff. Two flexible blades connected to the top compose the second part. Because of the uncertainties involved in the problem, the geometrical and mechanical properties that define the structural problem cannot be considered as deterministic quantities. This chapter presents a paper that models such uncertainties by using a fuzzy criterion. © 2003 Elsevier Science Ltd. All rights reserved.
