Superelastic SMA Dampers for Long-Span Bridges,historical ground motion recordings are applied to the bridge. The study sheds light on how well the SMA dampers can mitigate deck movements and reduce the amount of shear force and bending moment demands placed on the bridge towers during strong earthquakes.

Superelastic SMA Seismic Bridge Restrainers,y dependent on the alloy’s temperature, a sensitivity study is carried out using a thermomechanical SMA model to assess how temperature variability affects the effectiveness of SMAs as seismic restrainers for bridges. Finally, the efficacy of SMA restrainers compared to other conventional seismic retrofit devices is evaluated.

SMA Concrete Confinement: Column Applications, confinement technique, whether used individually or as a supplement to other confinement techniques (e.g., fiber-reinforced polymer), in mitigating the damage sustained by the columns during strong earthquakes. The efficiency of using SMAs in performing emergency repair of severely damaged columns is demonstrated experimentally.

Superelastic SMA Seismic Bridge Restrainers,es are typically used to mitigate this type of failure. However, due to their inelastic behavior, steel restraining cables are not always effective in preventing this damage. The superelastic behavior of shape memory alloys (SMAs) is sought in this chapter to develop bridge-restraining devices with

Superelastic SMA Dampers for Long-Span Bridges,s performance. A 3-dimensional (3-D) bridge model that takes soil-structure interaction into effect is equipped with SMA dampers and analyzed under ground motion excitation. The SMA dampers are installed at the deck-tower and deck-pier connections of the bridge. Three orthogonal components from two

SMA Composite Reinforcement for Concrete Structures,at corrosion issues. However, they are seldom taken into consideration in structures that require ductility and damping features because of the linear behavior of the typically utilized reinforcing fibers. This issue might be resolved by using superelastic shape memory alloy (SMA) fibers as reinforc
