The behavior of fiber reinforced cement composites (FRCC) can be described and quantified by a variety of parameters, such as strength and strain capacity, toughness index, and fracture energy, obtained from tests in tension or bending in a large number different configurations including varying specimen geometries and test setups. Depending on the details of the individual testing procedures, ...

Bridge management officials have expressed a keen interest in the use of low-cost and easy-to-install wireless sensors to record bridge responses during short-term load testing. To illustrate the suitability of wireless sensors for short-term monitoring of highway bridges, a wireless monitoring system is installed upon the Grove Street Bridge to monitor structural responses during static and dy...

Reinforced concrete structures need to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases strengthening of structural elements is much more economical than rebuilding the structure. Using HPFRCC with tensile stiffening behavior has been developed to strengthen the concrete structures over the recent few years. In this paper,...
