Retrofitting works are immensely essential for deteriorated and damaged structures in Engineering and Medical fields, in order to keep, or return to, the originality for safe guarding the structures and consumers. In this paper, different types of methods of retrofitting review notes are given based on the experimental, numerical and analytical methods results on strengthening the Reinforced ce...

The construction of offshore wind power pile foundations on artificial islands is a challenging task due to soil consolidation and additional loads that result in negative skin friction (NSF). In this study, comprehensive pile–soil interaction model established investigate the development NSF under action self-weight fill surcharge load. one-dimensional theory an ideal elastoplastic load transf...

Despite widespread research effort in recent years, design methods to estimate the shaft resistance of displacement piles continue to rely heavily upon empirical correlations. In an attempt to achieve a more reliable design approach several researchers have assembled databases of instrumented pile load tests and used these to propose new design methods e.g. American Petroleum Institute (API-200...

This paper proposed a novel supporting and retaining structure used to high-steep building slope reinforcement. It combined with an anti-sliding pile inclined column, which is as fulcrum on the upper part of pile. The mechanical characteristics are studied firstly by two methods numerical methods, respectively. Result shows that axial force will be evenly distributed along column body it provid...

Comprehensive field investigations into the axial cyclic loading behaviour of open-steel pipe piles driven and aged in low-to-medium density chalk identify conditions under which is stable, unstable or metastable. Post-cycling monotonic tests confirmed that stable cycling enhanced pile capacity marginally, while cases suffered potentially large losses shaft capacity. Metastable led to intermedi...
