Detailing for compression in reinforced concrete wall boundary elements: experiments, simulations, and design recommendations
type: CreativeWork
description: Reinforced concrete structural walls are one of the most common lateral force-resisting systems in buildings located in high seismicity regions. Walled structures are expected to provide significant strength and ductility under cyclic earthquake loading. In part, this expectation is based on the assumption that current design approaches suppress compression failure of the boundary element. However, compression failures observed following recent earthquakes in Chile (2010) and New Zealand (2011), suggest that the behavior of reinforced concrete walls may not meet expectation and further study is required. As part of a larger effort initiated by the National Earthquake Hazards Reduction Program (NEHRP) at the National Institute of Standards and Technology (NIST), a research program was developed to understand and improve the seismic behavior of concrete walls. This portion of that larger research program focuses on evaluation of, prediction of, and recommendations to improve boundary elements in structural walls. The research is divided into three phases. The first phase uses experimental research methods to evaluate the impact of salient study parameters on vertically loaded, large-scale rectangular reinforced concrete prism members that simulate the boundary element of a special concrete wall. This experimental program explored the effects of detailing of both transverse and longitudinal reinforcement and loading protocol on the compressive confined strength and strain capacity of boundary elements. In the second phase of research, these experimental results were combined with prior tests to evaluate commonly used confined concrete constitutive models and current detailing requirements in ACI 318-14. The test results indicate that rectangular reinforced concrete prism members designed to meet the minimum ACI 318-14 detailing requirements for special boundary elements exhibit little to no significant increase in compressive strength or deformation capacity as compare…
