Response Organization

The present data paper describes an experimental campaign on five thin T-shaped reinforced concrete walls (DOI: 10.6084/m9.figshare.3490754.v2), which includes: details on the test units, materials, test setup, loading protocol, instrumentation, main features of each unit's response, organization of the provided test data, and examples of derived data. The tests aimed at assessing the influence of wall thickness on member stability, the role of lap splices on damage distribution and displacement ductility, and the effects of the simultaneous application of out-of-plane loading on the member response. A set of five companion test reports, one for each of the tested units, are included in the data set and supplement the present manuscript.

Precast Walls

A wide range of reinforced concrete (RC) wall performance was observed following the 2010/2011 Canterbury earthquakes, with most walls performing as expected, but some exhibiting undesirable and unexpected damage and failure characteristics. A comprehensive research programme, funded by the Building Performance Branch of the New Zealand Ministry of Business, Innovation and Employment, and involving both numerical and experimental studies, was developed to investigate the unexpected damage observed in the earthquakes and provide recommendations for the design and assessment procedures for RC walls. In particular, the studies focused on the performance of lightly reinforced walls; precast walls and connections; ductile walls; walls subjected to bi-directional loading; and walls prone to out-of-plane instability. This paper summarises each research programme and provides practical recommendations for the design and assessment of RC walls based on key findings, including recommended changes to NZS 3101 and the NZ Seismic Assessment Guidelines.

Plastic Hinge Length

Large inelastic tensile strains and wide horizontal cracks primarily caused by in-plane loading, may lead to local out-of-plane deformations of the end regions of reinforced concrete (RC) walls within a buckled zone that comprises the plastic hinge length. Critical parameters that influence the onset of this failure mode have been studied through past experimental tests on RC prisms subjected to axial loading, which simulates the response of end regions of RC walls under in-plane demands. Missing from those studies is the effect of bidirectional loading protocols and the effect of the longitudinal reinforcement ratio on the hysteretic response. Therefore, 12 RC prisms with 3 longitudinal steel ratios representative of prototype boundary elements of typical special RC walls and piers walls were tested. The experimental results showed that the longitudinal steel content and the in-plane loading demands mainly govern the onset of out-of-plane buckling instability of planar RC walls.

Strength Models

This paper investigates the out-of-plane shear behavior of composite steel-plate-reinforced concrete walls (SC walls) and proposes their shear-strength-models based on plasticity theory limit analysis. For speedy, modular construction, SC walls are fabricated using double-skin steel plates with welded shear studs and sandwiching concrete between them. A review of current design formulas provides better understanding of bond-stress-dependent shear behavior relying on studs of SC walls. We conducted experiments on bondstrength-dependent arch and/or truss action to verify proposed shear-strength models with test results. Test results, including those from literature, agreed well with the strength anticipated by proposed formulas.
