Existing reinforced concrete (RC) columns with short splices in older-type frame structures are prone to either a shear or bond mechanism. Experimental results have shown that the force–displacement response of columns exhibiting these failure modes are different from flexure-critical columns and typically have lower deformation capacity. This article presents a failure mode-based approach for seismic assessment of RC columns with short splices. In this approach, first, the probable failure mode of the component is evaluated. Subsequently, based on the failure mode, the force–displacement response of the component can be predicted. In this article, recommendations are proposed for evaluating the probable failure mode, elastic rotation, drift at lateral failure, and drift at axial failure for columns with short splices experiencing shear, flexure, or bond failures.

现有的老式框架结构中具有短接头的钢筋混凝土（RC）柱容易受到剪切或粘结作用。实验结果表明，表现出这些破坏模式的柱的力-位移响应与抗弯临界柱不同，并且通常具有较低的变形能力。本文提出了一种基于失效模式的短接头钢筋混凝土柱抗震评估方法。在这种方法中，首先，评估组件的可能故障模式。随后，基于故障模式，可以预测组件的力-位移响应。在本文中，提出了一些建议，用于评估短剪力柱承受剪力，挠曲，
