Shear tabs are one of the most common shear connections used in conventional steel-frame construction due to their simplicity and relatively low cost. A significant amount of research has been done on standard shear tabs, where the connection eccentricity is small and the shear tab is affixed to a relatively rigid support such as a column flange. As such, design methods for standard shear tabs are well-established and they are used routinely in steel structures. However, far less information is available for the design of extended shear tabs, which are desirable for cases where joints can be simplified by extending the plate to keep the bolted connection region clear of any impediments to clean joint configurations and simple erection techniques.

抗剪翼片是传统钢框架结构中最常用的抗剪连接之一，因为其结构简单且成本相对较低。对标准剪力翼片进行了大量的研究，其中连接偏心率较小，且剪力翼片固定在相对刚性的支撑件上，例如柱翼缘。因此，标准抗剪翼片的设计方法已经得到了很好的建立，并且在钢结构中经常使用。然而，可用于扩展剪切翼片设计的信息少得多，这是可取的情况下，接头可以简化通过延长板保持螺栓连接区域清除任何障碍，清洁接头配置和简单的安装技术。
