摘要

In this paper, the axial behaviour of boundary elements of rectangular ductile reinforced concrete (RC) walls is investigated. For this purpose, axial tests on rectangular RC prisms representing the boundary zones of ductile RC walls are carried out. Critical design parameters influencing the local compression response of ductile wall boundaries are identified and the effect of these parameters on the axial response of RC prisms is experimentally investigated. Key parameters investigated in this study include loading history, transverse reinforcement detailing (arrangement, spacing and diameter), longitudinal reinforcement detailing (yield strength and area) and cover concrete. The influence of these parameters on the performance of RC wall boundary zones is discussed in light of the experimental observations of the prisms tested in this study. The experimental test results reaffirm the susceptibility of isolated wall boundary elements to the progression of large out-of-plane deformations and subsequent instability. The experiment test results show that loading history and transverse reinforcement detailing are the critical parameters that influence the failure modes of boundary zone prisms.
