“…For instance, apart from failure of the concrete pin in either shear or compression, it can be considered that the potential failure modes might be expected to be similar. Specific literature on strength of perforated plates for mechanically fastened joints [11,12] generally considers that the failure of the connection occurs in one of the four potential modes illustrated in Figure 2Figure 2: net-tension, shear-out (or tear-out), bearing, and cleavage. Net-tension is a lateral failure at the minimum cross-section perpendicular to the loading direction (Figure 2Figure 2a).…”

The authors have recently proposed an innovative connector system that consists on a Glass Fibre Reinforced Polymer (GFRP) perforated plate that is embedded into Steel Fibre Reinforced Self-Compacting Concrete (SFRSCC) layers. The connection is strongly based in the mechanical interlock assured by the dowels originated from the SFRSCC passing through the holes opened on the GFRP plates. In this study, an analytical framework to evaluate the load capacity of the connections when loaded transversally was developed based on experimental pullout tests presented in the companion paper (Part I). For a better understanding of the mechanical behaviour of the connections and to allow to make estimations of the load capacity of connection when it is conditioned by the rupture of the connector itself, pull-out pin-bearing tests with single-hole plates were executed to assess the effect of the type of GFRP on the strain distribution in the vicinity of the holes until the failure, as well as the estimated failure modes and load capacities of the connections.

“…Since it has been previously reported in the literature [10][11][12]16,17] that a pin bearing load configuration is the most conservative means for simulating a mechanically fastened joint by virtue of its encouragement of delamination and buckling, it is merely prudent to examine the local stress-strain behavior of an orthotropic variant of GLARE in this light as well [18]. The hardened side plates employ a 4.8 mm diameter loading pin for easier application to practical joint design and the assurance of geometric congruency to previous FE studies [16], to which the present research is related to.…”

“…Simply stated, the YDB mechanism can be described in the following manner: upon loading, delamination develops between the adjacent glass and aluminum layers; once this delamination reaches a critical length, the aluminum layers yield and then buckle, effectively transferring the load to the adjacent glass layers; however, since the glass layers themselves remain laterally unsupported, it is proposed that they too will buckle -along with the aluminum layers -thus precipitating joint collapse. The YDB mechanism builds upon previous observations [10][11][12][13]16,17] and rests upon reducing the heterogeneous nature of GLARE to the behavior of one of its constituents and one parameter within that constituent: that of the yield strength of the aluminum layers.…”

“…Numerous geometric configurations were tested, analogous to the work of Caprino et al [12], focused on the generation of bearing strength data for all possible failure modes; however, no significant insight was gleaned into the actual behavior of the joint in response to a pin bearing load configuration. The use of lock-in thermography, however, as a means of non-destructive evaluation did allow for in-situ observation of delamination between the aluminum and glass layers providing evidence for its role in preceding joint collapse.…”

Experiments enforcing a pin bearing loading configuration were performed on a fully orthotropic GLARE 4 variant. The protocol employed in such experiments stemmed from a similar methodology performed on quasi-isotropic GLARE variants though now incorporating a local measurement scheme using biaxial strain gauges rather than uniaxial ones. The aim of this local measurement was both the extraction of novel bearing yield strength values and the detection of buckling within the aluminum layers. The encouragement of delamination and buckling was key since they not only form an integral portion of the proposed yielding through delamination buckling (YDB) mechanism but in addition, the pin bearing configuration -which ipso facto, encourages the former(s) -has been identified in the literature as the most conservative and accurate means for analyzing joint behavior and collapse. Analytical calculations previously performed support the empirical findings and provide direct evidence for the hegemony of aluminum yield strength in joint collapse. The proposed and employed protocol has been shown to be effective across a comprehensive range of GLARE variants and may be extended analogously to other standardized testing methodologies.

“…The outer aluminium layer was etched away, revealing an area of delamination in the prepreg layer. Caprino et al [14] also provided some experimental evidence by presenting an optical micrograph showing extensive delamination between the glass and metal layers of a fully failed pin-loaded FML. Krimbalis et al [15] showed analytically that the stress needed to buckle the glass prepreg layers in GLARE Ò is small compared to that of the aluminium and concluded that the contribution of the glass layers to the overall bearing strength of the laminate is negligible.…”
