“…To verify the influence of vibrations on the curing of cement mortars, an experimental test was conducted on 24 vibrated and control (non-vibrated) samples of high-performance mortar (MGF) with polyacrylonitrile synthetic fibers. This experimental research is a part of a larger experimental campaign [34].…”

“…This allowed us to consider the contribution of the first three modes of vibrations. The dynamic response yielded by the decks was characterized by a preliminary finite element analysis (see details in [34]). The area under the PSD curve is the variance of the acceleration; its square root, the standard deviation, is related to the maximum acceleration produced via Monte Carlo simulations.…”

“…We observed that, usually, the maximum vertical acceleration was in the range of 0.2-0.4 m/s 2 ; to cover some other possible uncertainties, the PSD was scaled to obtain a maximum peak corresponding to 2 m/s 2 . More details of the procedure developed for the calculation of PSD are available in [34]. Figure 4b depicts a PSD function evaluated through the developed procedure.…”

Generally, during maintenance operations on bridges and motorway viaducts, the circulation of vehicles is limited or suspended. This causes significant economic losses due to the increase in the costs of transport: delays, increased fuel consumption, higher emissions of pollutants into the atmosphere, increased risk of accidents, etc. However, few studies have analyzed the influence of bridge vibrations on the final mechanical properties of the cement mortar placing during ordinary bridge service. As such, interest is increasing in repair techniques that could achieve high structural performance without reducing road service levels. This paper provides the results obtained through an innovative laboratory trials campaign that evaluated the influence of vibrations on the mechanical properties of high-performance mortar used for repairing bridge decks. The results of 24 cubic and prismatic specimens showed the relationship between the traffic-induced vibrations and the mechanical characteristics of the studied mortar. The findings can be considered as the first methodologic step that is necessary to address further field studies, drawing a detailed link between the repair techniques and transportation user costs. Based on the obtained results, a synthetic bridge management system framework was developed that merges the road function into the structural issue with the goals of increasing the resilience of road networks and optimizing the maintenance resources budget.

“…However, before developing new materials or optimizing existing materials, it is still necessary to clarify the performance degradation of existing materials under vehicle-bridge coupling vibration, and to determine the optimization direction of widening joint materials [14]. Fossetti et al conducted an experimental investigation on concrete subjected to induced vibrations, and the test results showed that compression strength can be degenerated by vibrations while tensile behavior will not be apparently affected [15].…”

Without interrupting the traffic on the old bridge, the connection of the widening bridge will cause disturbance to the concrete in the splicing position. In order to study the anti-disturbance performance of concrete material, the Normal Concrete (NC) material and the Ultra-High-Performance Concrete (UHPC) material were experimentally investigated by the vertical shaking table and X-ray computed tomography scanning. It can be learnt from tests that the compressive strength of NC and UHPC can be increased by about 10% to 20% after disturbance, while the flexural tensile strength and splitting tensile strength of both NC and UHPC can be reduced by about 20% to 25% and 10% to 20%, respectively. The elastic modulus of UHPC is not significantly affected by the vibration disturbance, and that of NC can be increased by about 20%. The setting time difference of the proposed NC material can be controlled within 100 min, and it can improve its anti-disturbance performance. Excessive vibration disturbance affects the internal structure of NC, while it has little effect on the distribution of steel fiber in UHPC. Due to the high cost of UHPC materials, it is recommended to analyze the joint performance requirements before the selection of splicing materials. If the stress requirement is not particularly high, it is still recommended to apply the proposed NC material for the splicing of widening bridge.
