Autonomous triggering system and measurement protocols for smart bridge testing
… triggering system for fast, economical bridge testing. Quantitative testing of bridges offers the ability to manage the structures better than with just qualitative inspections. The primary objectives of the proposed system are to acquire quantitative performance information from a load …

Study of Internal Strains Developed in Concrete Decks at Early Ages in Steel Continuous Bridges
… of Transportation (ARDOT) has identified bridge deck cracking shortly after concrete decks are placed and prior to applying traffic loads. Previous researchers have confirmed improper construction practices and design methods can lead to deck cracking. Currently, many contractors …

Excitation sources for structural health monitoring of bridges
… applied reliably to complex structures such as bridges. VBDD methods require reliable estimates of modal parameters (notably natural frequencies and mode shapes) in order to assess changes in the condition of a structure. This thesis presents the results of experimental and numerical studies …

Global Dynamic Characterization and Load Rating of Bridge Structures Utilizing Economical Dynamic Excitation Devices
<p>Experimental modal analysis (EMA) of bridges and other civil structures can be used to acquire quantitative data describing their condition, and enhance opportunities for structural health monitoring and related fields. The use of EMA on civil structures has been limited by the high cost of the …

Rapid Condition Assessment of Bridges By Falling Weight Deflectometer
… to rapidly assess the condition of an in service bridge through the evaluation of its modal properties. Tests were conducted on two bridges, a Parker Pony Truss and a modern concrete deck on rolled steel beam bridge. Two full tests were performed on these structures with a hand held impact hammer …
