The paper provides a critical appraisal of the events surrounding the unexpected settlement of large-diameter monopile foundations for offshore wind energy converters, and will detail experimentation that is to be undertaken to determine the extent of the wear failure mode in such structures. The potential for wear deterioration at the grout-steel interface has been caused by the lack of axial ...

The quality of grouted sleeve has a significant influence on the performance splice. Incompactness infilled grout is inevitable in grouting. To investigate tensile behavior splice sleeves due to different compactness, monotonic tests connectors were performed at compactness 100%, 90%, 70%, and 50%, respectively. bond-slip analytical model rebar-grout was deduced by fitting test data, formula fo...

Assuming that the ground anchor is connected with rock–soil of sidewall by a tangential linear spring, load transfer model fully grouted established using spring element method, and analytical solutions displacement, axial force, shear stress distribution in upper lower parallel strata foundation sandwich are given, respectively. Corresponding to above two kinds alternating strata, mechanical b...

The pressure grouted helical anchor is an innovative soil-cement using the simultaneous drilling and grouting technique. This paper presents a field study numerical simulation to analyze load-displacement behavior of single anchored in marine soft soil deposit. Three full-scale anchors were tested under monotonic tension loading analysis effect Influence helix plates configuration on lifting ca...

Abstract This paper briefly describes the methodology, performance and obtained results of unique experiments performed on original I-73 precast bridge girders. The main objective was to determine actual anchorage length corroded-through fully grouted prestressing reinforcement (prestressing wires), which is important for determination residual load-bearing capacity prestressed structures. Obse...
