钢结构设计的AISC LRFD规范（LRFD，1999）包含了通常称为块体剪切的规定。从概念上讲，这是指一块材料的位移。它通常与螺栓连接的细节相关，因为在这种情况下会出现面积减小，但原则上它也可以出现在焊接细节中。然而，本文仅涉及螺栓连接。该检查已确定，使用LRFD规范规则的块剪切导致保守设计的节点板，非保守设计的帽梁，和令人满意的结果的角度。重要的是，在大多数情况下，这些规则并不反映在测试中观察到的故障模式。
The AISC LRFD specification (LRFD, 1999) for the design of steel structures contains provisions for what is customarily termed block shear. Notionally, this refers to the displacement of a block of material. It is usually associated with bolted details because a reduced area is present in that case, but in principle it can also be present in welded details. This paper deals only with bolted connections, however. This examination has identified that use of the LRFD Specification rules for block shear leads to conservative designs for gusset plates, non-conservative designs for coped beams, and satisfactory results for angles. Importantly, in most cases these rules do not reflect the mode of failure observed in the tests.
