“…Dynamic analysis has been done by applying 190 concurrently both horizontal components of the selected earthquakes and their amplified 191 1 Record serial number [29] 2 Magnitude of earthquake 3 Source distance 4 Shear wave velocity 5 Peak ground acceleration counterparts successively until the failure of the bridges. Because displacement perpendicular to the longitudinal axis of the bridge is the main cause of damage to masonry arch bridges [29,43,44], the ground motion component with the largest PGA is applied perpendicular to the longitudinal axis, and the other component is input in the direction of the bridge's axis. After the analysis, the response history of the control points is determined.…”

“…Although the IDA method is the best method to explain the proper understanding of the behavior of the structure from the elastic state to failure, it is evident that the research works involving this method for masonry arch bridges are very rare. Mehrbod et al [29] investigated the earthquake vulnerability of two stone arch bridges using the IDA method. The failure process and dominant damage patterns of both bridges were identified.…”

One of the most important tools for determining the vulnerability of structures to earthquakes is use of fragility curves. Considering the importance of existing masonry arch bridges in transportation networks, in this research, the process of determining the fragility curve by the analytical method through using the discrete element method (DEM) is discussed. The seismic behavior of two railway bridges is investigated using the incremental dynamic analysis method (IDA). Bridge A is smaller and is totally 66.7 m long and has four similar arches spanning 12 m each. Bridge B is the larger bridge, with a length of 160 m. It has a large central arch span of 48.6 meters and a height of 22.8 meters. By introducing an appropriate number of control points in the bridge body, the seismic response of the bridges are obtained. By examining the IDA curves and status of damage in the bridges, the performance criteria for immediate occupancy (IO), life safety (LS), and collapse prevention (CP) limit states have been determined. The fragility curves of the bridges are calculated for the above three limit states. The results show that both bridges require seismic strengthening for the IO performance level with a probability greater than 90%. Also In the event of design earthquake, larger bridge will not be safe with a probability of more than 50% for the LS limit state, and the probability of exceedance the CP limit state for bridge A is 12% and bridge B is 32%.

This review explores the use of Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber cloth as an innovative solution for the repair and reinforcement of concrete structures. UHMWPE is a polymer formed from a very large number of repeated ethylene (C2H4) units with higher molecular weight and long-chain crystallization than normal high-density polyethylene. With its superior tensile strength, elongation, and energy absorption capabilities, UHMWPE emerges as a promising alternative to traditional reinforcement materials like glass and carbon fibers. The paper reviews existing literature on fiber-reinforced polymer (FRP) applications in concrete repair in general, highlighting the unique benefits and potential of UHMWPE fiber cloth compared to other commonly used methods of strengthening concrete structures, such as enlarging concrete sections, near-surface embedded reinforcement, and externally bonded steel plate or other FRPs. Despite the scarcity of experimental data on UHMWPE for concrete repair, this review underscores its feasibility and calls for further research to fully harness its capabilities in civil engineering applications.
