Steel-concrete-steel (SCS) sandwich panels are composed of two steel plates with low thicknesses and high densities and strengths and one thick layer between both plates with low strength and density known as core that is composed of concrete. Cohesive material-epoxy resin or shear connectors are usually used to connect the plates to the concrete core. SCS sandwich composites are being develope...

This study investigates the shear capacity of aluminum alloy honeycomb sandwich plates connected by high-strength, ordinary, or self-tapping bolts. For that purpose, experimental tests and finite elements are carried out. The failure of a high-strength bolt connector is driven by bending deformations developed in the bolt that deform connection plate and pad openings. In the case of ordinary bo...

In this study, the effect of corrosion on the static behavior of stud shear connectors was investigated. An innovative test setup for single stud shear connectors was designed and established. Two series of specimens having different stud diameters were fabricated and tested. The test specimens were firstly corroded to different corrosion rates by the electronic accelerating method. Static load...

For steel–concrete composite structure, a new type of stud–PBL shear connector can improve the resistance interface, and polypropylene fiber ceramsite concrete reduce self-weight. Therefore, investigating behavior connectors for steel–ceramsite structures bears significance. In this study, static testing numerical simulation push-out specimen were first conducted. The influencing factors bearin...

A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedd...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
