Failure modes and their corresponding tension strengths of thread-fixed one-side bolted T-stub were investigated experimentally and theoretically.
And under the design load, the bolted T-stub was still in elastic state, which demonstrated the applicable of the thread-fixed one-side bolted T-stub.
Tests were carried out to investigate the one-side bolted T-stub through thread holes under tension strengthen with backing plate.
Theoretical and numerical analyses showed that the thread hole could provide enough clamping force to fix the high strength bolt, which assured that the one-side bolted T-stub connection would not fail caused by pre-mature thread failure.
The failure mechanism of thread-fixed one-side bolted T-stubs under tension was investigated by a finite element model to provide basic knowledge for its potential application in bolted beam-column endplate connection.
The comparison between test results and calculated results from design methods indicated that the proposed design methods could be used to predict the tension strength and failure modes of the one-side bolted T-stub through thread holes and strengthened with screwed backing plates.
Finally, a full-scale FRP truss-UHPC hybrid bridge model with one bolted side and the other bolted-bonded side in FRP joints, was tested under varies loading scenarios.
In this study, the flexural behaviour of bolted side-plated (BSP) reinforced concrete beams was investigated experimentally.
A numerical model was developed using the finite element method (FEM) software OpenSees to simulate the shear behavior of bolted side-plated (BSP) reinforced concrete (RC) beams.
Although the bolted side-plating (BSP) technique is feasible to upgrade the shear capacity of reinforced concrete (RC) beams, related studies on its strengthening effect have yet to be sufficient.
Local buckling may occur on the compressive edge of steel plates in bolted side-plated (BSP) beams, which usually leads to premature failure analogous to over-reinforced concrete beams.
