Researchers at the University of British Columbia (Okanagan campus) examined a variety of bridge types along with design requirements under the Canadian Highway Bridge Design Code. As part of the research, the seismic performance of shape memory alloy reinforced and post-tensioned bridge piers have been tested in the University’s Applied Laboratory for Advanced Materials and Structures (ALAMS). The results, published in the Journal of Structural Engineering, ASCE, point out that bridges are being built to withstand the force of an earthquake, however they are being overbuilt, resulting to unnecessary construction expenses.
UK's Royal Mail has just issued a set of first class stamps depicting the 10 most historical bridges across the country. According to Royal Mail, the series "demonstrates leaps in engineering" performed by progressive architects and engineers.
Bridges, as the structures which connect two separated parts of land, make easier and faster our transportation. The materials, the shape and the design differentiate one bridge from the other. Although, there are lot of impressive bridges worldwide, one that stands out is the Helix Bridge in Singapore.
