A limited test data are available for double-bolt line connection in a single angle tension member, which failed in block shear. To address this, twelve single angle tension members with a double bolt-line connection was reported in this paper, considering the block aspect ratio and connection length as the test parameters. All the tested specimens were failed in block shear. For the tested specimens, numerical analysis was performed, which shows good agreement with experimental results. Experimental outcomes were then compared with the current design provisions present in the IS 800, AISC, CSA, AIJ, EC 3, SBC, and with other existing proposed models. These standards and models show some discrepancies with regard to the experimental results. This discrepancy was due to the shear failure plane position as assumed in the design standards. Those shear planes were specified in the standards as net and gross shear planes. However, the experimental and numerical investigation shows that between the gross shear plane and the net shear plane lies the actual shear failure plane. Based on this, the block shear mechanism was modified and proposed a rational equation that provides a more exact prediction of block shear capacity than the current design standards and the other existing models. The proposed block shear equation shows the precise forecast for both single and double-bolt line connections used in a single angle tension member.

有限的测试数据可用于单角度受拉构件中的双螺栓管线连接，但在块剪切中失败。为了解决这个问题，在本文中，以块长宽比和连接长度为测试参数，报道了十二个带有双螺栓管线连接的单角度张紧构件。所有测试的样品均未通过块剪切。对于被测样品，进行了数值分析，与实验结果吻合良好。然后将实验结果与IS 800，AISC，CSA，AIJ，EC 3，SBC中的当前设计规定以及其他现有拟议模型进行比较。这些标准和模型在实验结果上显示出一些差异。这种差异是由于设计标准中假定的剪切破坏平面位置引起的。这些剪切平面在标准中指定为净剪切平面和总剪切平面。然而，实验和数值研究表明，总剪切平面和净剪切平面之间是实际剪切破坏平面。在此基础上，对砌块剪切机理进行了修改，并提出了一个有理方程，该方程可以提供比当前设计标准和其他现有模型更为精确的砌块剪切能力预测。拟议的块体剪切方程式显示了在单角度受拉构件中使用的单螺栓连接和双螺栓连接的精确预测。修改了块体剪切机制并提出了一个有理方程，该方程比当前的设计标准和其他现有模型提供了更精确的块体剪切能力预测。拟议的块体剪切方程式显示了在单角度受拉构件中使用的单螺栓连接和双螺栓连接的精确预测。修改了块体剪切机制并提出了一个有理方程，该方程比当前的设计标准和其他现有模型提供了更精确的块体剪切能力预测。拟议的块体剪切方程式显示了在单角度受拉构件中使用的单螺栓连接和双螺栓连接的精确预测。
