“…Similar to the method used in reference, 36 here, a girder with a damage index value falling in the interval D = 0-0.2, D = 0.2-0.4, D = 0.4-0.6, and D = 0.6-1.0 are defined as minor damage, moderate damage, severe damage and failure, respectively. Furthermore, according to the ideas in referernce, [37][38][39] the principle used to distinguish between moderate damage and severe damage depends on whether the bridge superstructure can operate normally through appropriate structural repairs. If the bridge superstructure can continue to function normally after comprehensive structural repairs, the damage of the girder would be moderate.…”

Accidental collisions from overheight vehicles often result in significant damage of bridges. To ensure the safety of the bridge structure, it is essential to develop a method to evaluate the damage caused by these impact loadings. This study aims to investigate the damage mechanism of a prestressed concrete (PC) box girder bridge subjected to overheight vehicle impact using the finite element analysis method. Parametric analyses were performed to study the effects of various factors on the impact force and deformation performance of the bridge. In addition, a damage assessment formula, based on the vertical residual bearing capacity, is proposed to evaluate the damage state of the impacted PC box girder. A mass–velocity (m–v) curve is developed to characterize the damage levels of the impacted PC girder under different vehicle velocity and mass conditions. Then, a theoretical equation for predicting the maximum impact force during the vehicle‐bridge collision is developed. The numerical analysis results show that vehicle‐related parameters have a significant influence on both impact force and local damage of the PC box girder bridge. The proposed mass–velocity (m–v) curve can be used to evaluate the damage state of the PC box girder by relating the performance levels of the girder to each damage index. Moreover, the predicted maximum impact force can be used as an important index to assess the extent of the local damage of the PC box girder.

“…For example, 61% of interchange bridges have been damaged due to overheight collision forces in the United States and such systems include about 14% of whole bridge damages [12]. The mechanism and reasons for an over-height vehicle-bridge collision are complicated due to intricate dynamic effects, variability in forces, and different types of bridge structural and geometry [13]. The collision between an overheight truck and a prestressed concrete box girder bridge was studied based on the finite element-based software by Kong et al in 2020. In this article, the damage to the impacted girder and the collision force are analyzed.…”

Railway bridges are built to allow trains to cross over highways, valleys, or other transportation infrastructure. In recent years, the number of railway bridges subjected to over-height collision forces has increased. These collisions damage the bridge and affect the safety of the running train. In this investigation, first, a 3D GT26 train-track-bridge interaction model was created to study the effects of collision forces applied to the bridge superstructure and not to the bridge piers as a novelty of this research using the finite element analysis. Then, the dynamic responses of the railway bridge due to the GT26 train load and subjected to over-height collision forces were obtained. Finally, the different sensitivity analyses describe that changing the length of the collision area, the bridge span, and the value of collision forces affect the dynamic responses of the bridge in the contact area. The results show that maximum lateral displacement of the concrete girder in case of assuming the GT26 train 3D model plus over-height collision force is 8.88% less than the case in which considering only freight train axle-load and same over-height collision force apply to the bridge superstructure, and its value reduces from 45 mm to 41 mm. The maximum lateral displacement of the bridge deck is reduced by about 71% by increasing the collision area length from 0.2 m to 1.2 m and at the impact area rises about 43.5% by changing collision speed from 48 km/hr to 144 km/hr as collision force from 7753 kN to 13370 kN.

“…Traditional repair techniques involving posttensioning using external or near-surface mounted (NSM) steel and fiber-reinforced polymer (FRP) tendons involve the use of heavy hydraulic jacking equipment, and intricate anchorage systems, which lead to long construction times and, in case of bridges, high management of traffic costs. 1 In response to this issue, a rapid heat-induced posttensioning technique using unbonded NSM shape memory alloy (SMA) wires was proposed, and prototype reinforced concrete beams posttensioned with SMA wires were evaluated experimentally. 2 The suggested technique relies on the ability of SMA to recover seemingly plastic deformation upon heating.…”

A novel posttensioning technique using nickel‐titanium‐niobium (NiTiNb) shape memory alloy (SMA) wires for the repair of reinforced concrete beams was evaluated numerically. A finite element model of a reinforced concrete beam was developed within a damage mechanics framework to simulate concrete cracking and subsequent posttensioning. The predicted yield and ultimate moment capacities of the simulated posttensioned beams were up to 14% less than the corresponding experimental results. Cumulative discrepancies in the assumed material models led to the conservative model results. The effects of concrete tensile damage, SMA reinforcement ratio, SMA‐concrete interaction (bonded vs. unbonded), and the effective prestress on the service and ultimate behavior of the posttensioned beam were evaluated. Partial loss of prestress in the SMA due to elastic shortening of the concrete was insignificant (<3%) because of the relatively low elastic modulus of the SMA. Increasing the SMA reinforcement ratio by three times increased the yield moment of the posttensioned beam by 99%. Reducing the effective SMA prestress to 80% of the initial prestress to account for the possible losses resulted in a decrease in the yield moment by up to 7.8%.
