This paper examines the trends that may influence the future shape of engineering structures. Among the most important factors are: impact of the computer on analysis and design, developments in traditional materials and the introduction of new ones, advances in research, the adoption of limit-state structural design codes, new approaches to construction and, of course, the demands of society as influenced by both
political and economic considerations. Resulting from these trends, some possible scenarios for the development of engineering structures on land, on sea and in the air are briefly sketched.
