“…The behavior of the stud connectors has been broadly investigated by many researchers (Kim et al, 2011; Lam and Ellobody, 2005; Mirza and Uy, 2010; Nie et al, 2008; Smith and Couchman, 2010; Xue et al, 2008). The deterioration in the strength of stud connectors due to fatigue damage has also been reported (Coughlan, 1987; Dai and Richard Liew, 2010; Dogan and Roberts, 2012; Johnson, 2000; Lin et al, 2013; Oehlers, 1990; Wang et al, 2014). However, there is no research reported about the deterioration in the strength of stud connectors due to corrosion.…”

In this study, the effect of corrosion on the static behavior of stud shear connectors was investigated. Two series of push test specimens having different stud diameters were fabricated according to Eurocode 4. The test specimens were first corroded to different corrosion rates by electronic accelerating method. Static loading tests were then performed to obtain the load-slip curves and ultimate strengths of corroded test specimens. Material properties of the concrete and steel studs used in the test specimens were also measured. Actual corrosion rates were measured from the studs obtained from the tested specimens. Design methods specified in current design standards are used to predict the design strengths of test specimens. It is shown that the design strengths are unconservative for corroded test specimens. Therefore, a new design equation is proposed which enables the designer to consider the effect of corrosion.

“…To overcome this disadvantage and develop slim deck for offshore constructions, J-hook connectors were developed by Liew et al [6] as shown in Figure 1 (d). From the previous studies, sandwich structure with J-hook connectors exhibited excellent performances under impact, blast, and fatigue loadings [7,8]. This type of structure has great potential for applications in hulls of cargo tank, bridge decks, offshore decks, shear walls, and protective structures as shown in Figure 2.…”

Steel-concrete-steel (SCS) sandwich structure with ultra-lightweight cement composite core has been developed and proposed for applications in offshore, bridge and building constructions. A new form of J-hook connector is introduced to bond the steel face plates and cement composite core to form an integrated unit which is capable of resisting extreme loads. Design formulae were proposed to predict the shear, tension, and their interaction resistances of J-hook connectors. Thirty push-out tests and eighteen tensile tests were carried out on steel-concrete-steel sandwich plates with J-hook connectors embedded in different kinds of concrete to determine their shear and tension resistance, respectively. Nonlinear finite element (FE) model was also developed to predict the load-slip and ultimate behavior of J-hook connectors under combined shear and tensile loads. Finally, the design formulae were validated by comparing the predicted results with those obtained from tests and FE analyses. The formulae may be used to evaluate the tension, shear, and shear-tension interaction resistances of the J-hook connectors in steel-concrete-steel sandwich composite structures.

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 loading tests were then performed to obtain the load-slip curves and ultimate strengths of the corroded test specimens. The actual corrosion rates were measured from the studs obtained from the tested specimens. The test results were compared with the push out test specimens having similar corrosion rates. It is shown that the test results obtained from the single stud shear connectors are conservative compared with the corroded push test specimens, which prove the validation of the single stud shear connector test method. The effect of corrosion on the behavior of stud shear connectors was also presented.
