Aesthetics in Concrete Bridge Design

Esthetics in Concrete Bridge Design, ACI MP-1
Editors: Steward C Watson, M.K. Hurd
1990
In the present age of heightened public awareness, bridge design engineers can no longer be allowed to limit their activity to static calculations and monitoring of construction. The public will not permit us to create unattractive structures. After a bridge is constructed it actually changes its particular part of the environment for 50 years or longer. There is a growing perception that ugly bridges actually are a form of pollution and in fact seem to breed discontent and despair.

The selection of a bridge design--whether the most attractive, the best for its structural qualities, or the most economical for the pUblic--is often in the hands of those who are not specialists in bridge design. with this in mind ACI committee 124, Concrete

Esthetics, decided to try to identify the fundamentals of bridge esthetics, which could be shared among decision makers and professionals alike. We searched worldwide, asking distinguished members of the bridge design fraternity as well as their architectural counterparts to help us in this task. The result was four symposium sessions presented at ACI conventions, two in Seattle, Washington on November 12-13, 1987, and two in Orlando, Florida March 24, 1988. These proceedings constitute the record of the symposia where the question was addressed. In approving the papers for publication, committee

124 waived the peer review process usually followed for ACI symposium volumes. The reason for this decision is that the content is highly subjective, nondimensional, and generally not quantitative. This reflects the nature of esthetics as a branch of philosophy and respects each writer's right to expression of a personal point of view. critiques or criticism may be appropriate as discussion later, but they have not been used to influence authors of these invited papers to change their drafts.

Information contained in these proceedings indicates the present state of the art. It is hoped
that it will serve to time-bind this generation of bridge designers and builders to those generations to come. If we have been successful in this endeavor, then all the hard work of the many people involved will have been worthwhile.
