Structural health monitoring through field instrumentation has been carried out successfully on many highway bridges to monitor the short-term and long-term performance of structures. Properly designed and strategically placed instruments can help collect valuable data regarding the condition, the stress and strain, deflection, temperature gradients, and the time-dependent properties, such as c...

three unconventional details for plastic hinges of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span reinforced concrete bridge. shape memory alloys (sma), special engineered cementitious composites (ecc), elastomeric pads embedded into columns, and post-tensioning were used in three different piers. the bridge model was subjected to...

Careful maintenance is essential to ensure the long-term serviceability of bridges. It is therefore necessary to establish a database which has a large capacity for storage of time-series data including structural properties at construction completion, inspection records, and repair and maintenance records, and which utilizes state-of-the-art information and telecommunication technologies to al...
