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...

Micro piles are small diameter pile (less than 300mm). generally used when there difficult ground conditions, such as natural or man-made obstructions, sensitive with adjacent structures, limited access/low headroom. drilled and grouted friction piles. Each includes steel elements that bonded into the bearing soil rock – usually cement grout. The stratum is logged during installation drilling t...

This study investigated the seismic performance of cementitious grout filled coupler and sleeve connections in precast wall panels under cyclic lateral loading. The effectiveness these enhancing concrete walls was evaluated. In many countries, grouted are preferred option, whereas were more commonly utilized India due to belief that a greater portion dowel being enhances structural stability. T...

To study the failure modes, bearing capacity, ductility, and sleeve strain of grouted lapping connectors, 36 specimens were tested under uniaxial tensile load. The test results show that sleeves are longitudinal tension at beginning, which changes to compression in late stage loading, changing load increases gradually with lap length. force transmission path mechanical mechanism connectors anal...
