Form and Structure in Bridge Design

The work of designing should be considered as a rational, cognitive process that it has to propose concrete solutions based on real needs. For a structure to be not only functional but also socially acceptable, there are a number of variables involved which can be divided into subjective and objective considerations. Subjective variables are qualitative in nature, having to do with aesthetics, with judgements of taste which are not necessarily universal. The judging of a structure as handsome or ugly remains an individual opinion and thus highly problematic A proper method for the analysis of subjective variables, however, can lead to a choice of form which is justifiable regardless of whether an individual perceives the work as handsome or ugly. This method should enable a project to be developed along lines that can command the validity of a logical process.
