“…The accuracy of the numerical model was verified using data from tests of six experimental programs reported in the literature [9,11,22,[25][26][27]. The cases listed above were selected because they not only describe comprehensively geometric, material and structural response details, but also four of them examined compression loading, whereas the rest accounted for in-plane shear loading.…”

“…This modelling approach has been validated using experimental results reported in the literature. To be more specific, wall specimens tested by Epackachi et al [22], Ozaki et al [11], Choi et al [26] and Zhang [27] did not include side plates resulting in a partially confined concrete model, whereas specimens tested by Akiyama et al [25] and Usami et al [9] included side plates resulting in a fully confined concrete model. Additionally, it has been assumed that the confinement provided by the steel plates exceeds by far the confinement provided by the shear connectors and as a result, the latter has been neglected.…”

Double-steel plate concrete composite shear walls are being used for nuclear plants and high-rise buildings. They consist of thick concrete walls, exterior steel faceplates serving as reinforcement and shear connectors, which guarantee the composite action between the two different materials. Several researchers have used the Finite Element Method to investigate the behaviour of double-steel plate concrete walls. The majority of them model every element explicitly leading to a rather time-consuming solution, which cannot be easily used for design purposes. In the present paper, the main objective is the introduction of a three-dimensional finite element model, which can efficiently predict the overall performance of a double-steel plate concrete wall in terms of accuracy and time saving. At first, empirical formulations and design relations established in current design codes for shear connectors are evaluated. Then, a simplified finite element model is used to investigate the nonlinear response of composite walls. The developed model is validated using results from tests reported in the literature in terms of axial compression and monotonic, cyclic in-plane shear loading. Several finite element modelling issues related to potential convergence problems, loading strategies and computer efficiency are also discussed. The accuracy and simplicity of the proposed model make it suitable for further numerical studies on the shear connection behaviour at the steel-concrete interface.

“…Subsequently, the steel plates buckle, the rebar neighboring to the buckling location resists excessive tensifle forces, as well as the tensile forces rises with the reduction of the rebar spacing [7]. Validation studies have been undertaken using the experimental results of four axial compression tests reported by Akiyama et al (1991) and Usami et al (1995), Choi et al (2014) and Zhang (2014) [8][9][10][11].…”

This research is presented experimental and numerical investigations of composite concrete-steel plate shear walls under axial loads to predicate the effect of both concrete compressive strength and aspect ratio of the wall on the axial capacity, lateral displacement and axial shortening of the walls. The experimental program includes casting and testing two groups of walls with various aspect ratios. The first group with aspect ratio H/L=1.667 and the second group with aspect ratio H/L=2. Each group consists of three composite concrete -steel plate wall with three targets of cube compressive strength of values 39, 54.75 and 63.3 MPa. The tests result obtained that the increase in concrete compressive strength results in increasing the ultimate axial load capacity of the wall. Thus, the failure load, the corresponding lateral displacement and the axial shortening increased by increasing the compressive strength and the rate of increase in failure load of the tested walls was about (34.5% , 23.1%) as compressive strength increased from 39 to 63.3 MPa for case of composite wall with aspect ratio H/L=1.667 and H/L=2, respectively. The effect of increasing aspect ratio on the axial load capacity, lateral displacement and axial shortening of the walls was also studied in this study. Compared the main performance characteristic of the testing walls, it can be indicated that the walls with aspect ratio equal to (2) failed under lower axial loads as compared with walls with aspect ratio equal to 1.667 ratios by about (5.8, 12, 15.6 %) at compressive strength (39, 54.75, 63.3 MPa), respectively and experienced large flexural deformations. The mode of failure of all walls was characterized by buckling of steel plates as well as cracking and crushing of concrete in the most compressive zone. Nonlinear three-dimensional finite element analysis is also used to evaluate the performance of the composite wall, by using ABAQUS computer Program (version 6.13). Finite element results were compared with experimental results. The comparison shows good accuracy.

Στην παρούσα διατριβή διερευνήθηκε η συμπεριφορά ενός καινοτόμου δομικού στοιχείου, του σύμμικτου διχαλύβδινου τοιχώματος. Βασικό σκοπό της έρευνας αποτέλεσε η εκτίμηση της συμπεριφοράς των συνδέσμων διάτμησης σε ένα Σ.Δ. τοίχωμα, γιατί ο ρόλος τους είναι κρίσιμος για την εξασφάλιση της πλαστιμότητας και της σύμμικτης δράσης. Για τη συγκεκριμένη διερεύνηση κρίθηκε απαραίτητη η κατανόηση της λειτουργίας των Σ.Δ. τοιχωμάτων και η ανάδειξη των κρίσιμων παραμέτρων λειτουργίας για κάθε περίπτωση φόρτισης. Συνολικά μελετήθηκε η απόκριση των Σ.Δ. τοιχωμάτων σε θλιπτική, σεισμική, εκτός επιπέδου και θερμική φόρτιση.
