Cable Stayed Bridges

AbstractMany researchers have carried out experimental and numerical investigations to examine building structures’ response to explosive loads. Studies of bridges subjected to blast loads are limited. Hence, in this study, we present a case study on a cable-stayed bridge, namely, Charles River Cable-Stayed Bridge-Boston, to assess its robustness and resistance against the progressive collapse resulting from localized failure due to blast loads. Three different blast scenarios are considered to interpret the bridge performance to blast loads. To monitor the progressive failure mechanisms of the structural elements due to blast, pre-defined plastic hinges are assigned to the bridge deck. The results conclude that the bridge is too weak to sustain the blast loads near the tower location, and the progressive collapse is inevitable. Hence, to preserve this cable-stayed bridge from local and global failure, structural components should be more reinforced near the tower location. This case study helps the designer better understand the need for blast resistance design of cable-stayed bridges.

Bridge Performance

The Miramichi bridges in New Brunswick, each of six 200-ft (61-m) spans, were built as part of the Intercolonial Railway by Sir Sandford Fleming in 1871–75. When construction of the Northwest Bridge started, it was found that early borings were incorrect and the layer of gravel and sand on which the piers were to rest was underlain by deposits of silty sand and clay–silt. The caissons of the piers were therefore enlarged in order to spread the load better. On observing settlements during construction, Fleming stopped the work and preloaded each pier in excess of the design load. He resumed construction when he observed that settlements had stopped.The level of the bridge piers has been measured periodically since 1914. Recent borings have been made, giving a basis for analysis of the bridge performance. Calculated primary settlements are compared with those measured during construction. Surveyed pier movements are adjusted to reduce errors, and compared with calculated secondary settlements. It is deduced that the piers have settled at a rate equal to or less than that indicated by the theory of secondary compression.The bridge is continuing to perform in a predictable and safe manner, providing an outstanding example of early Canadian engineering.
