Accelerated aging methods are needed to estimate the potential long-term serviceability of building materials under environmental conditions of use.
The long-term serviceability of FRP-strengthened structures is a huge concern because of the lack of long-term performance data and suitable models, which can adequately represent this performance.
Creep is essentially important to cementitious materials since excess deformation can negatively impact the long-term serviceability and sustainability of concrete structures (Neville 1981; Bažant 2001; Mindess et al. 2003; Singh et al. 2013; Li 2012; Ye et al. 2015).
Hence, non-linear buckling analysis should be employed in assessing the long-term serviceability limit state of pin-ended and fixed CFST shallow arches in design practice, although linear buckling analysis is capable of predicting the in-plane buckling loads for pin-ended CFST deep arches.
The advanced analysis can predict more accurately possible failure modes of a structure, exhibit a more uniform level of safety, and provide a better long-term serviceability and maintainability.
In the elastic phase, the adhesive offers sufficient stiffness to provide continuity of stiffness over the joint, thus meeting the short- and long-term serviceability requirements for the structure.
Critical combinations of panel geometry, material properties, and reinforcement details can lead to long-term serviceability problems (Young et al. 2012; Wenzlick 2008).
The failure of ground improvements can either be short-term ultimate limit state failure (e.g. slip failure and tension cracks) or long-term serviceability limit state problems (e.g excessive differential settlement).
As excessive dynamic displacement affects the long-term safety, serviceability of the bridge and comfort of the passenger, hence, main focus of study is on the dynamic displacement and fundamental mode of vibration of the bridge.
This may seriously affect the long-term safety, serviceability of the bridges and comfort of the passengers.
Our recent studies have shown that an important factor of main pipelines serviceability loss under their long-term service is the in-bulk metal degradation of the pipe wall.
