Maintenances are necessary to ensure the safety and serviceability of existing bridges.
The resulting displacements should avoid the occurrence of significant damage and preserve the serviceability of existing structures.
To ensure the safety and serviceability of the existing tunnels, attention has been paid to the basement-tunnel interaction.
This finding, and the measured GRFs, can be used for more accurate vibration serviceability assessments of existing and new footbridges.
Finally, the serviceability of the existing design methods for corrugated steel plate shear walls was examined, which proved that the plate-frame interaction model could predict the shear strength and initial stiffness of the corrugated steel plate shear walls with good accuracy.
Natural deterioration of mild steel exposed to marine environment compromises the long-term integrity, serviceability and safety of new and existing infrastructure and increases the risk of structural failure.
Hot mix asphalt (HMA) overlay is used for strengthening the existing pavement structure, correcting the surface defects, and improving pavement serviceability.
Maintenance of existing road pavements assumes increasing interest as the traffic growing produces a faster deterioration of road infrastructures compromising safety and pavement serviceability.
Various indicators like Pavement Condition Index (PCI), Present Serviceability Rating (PSR), Roughness Index (RI), etc. have been commonly used to assign a maintenance strategy for the existing pavements.
For existing reinforced concrete structures exposed to saline or marine conditions, there is an increasing engineering interest in their remaining safety and serviceability.
