SHEAR 82-1 STRENGTH CALCULATION ABOUT SHEAR AND BEARING OF CONNECTING MEMBERS I\ Characteristics of loads and deformation of connecting members: 1)Connecting member The structure member that connects one member to another is called the connecting member Such as: bolts rivets\ keys etc. The connecting member is small, but it plays the role of passing loads bolt Characteristic: It can P P pass general loads and can be dismounted

§2－1 STRENGTH CALCULATION ABOUT SHEAR AND BEARING OF CONNECTING MEMBERS 1、Characteristics of loads and deformation of connecting members: 1)Connecting member The structure member that connects one member to another is called the connecting member. Such as：bolts、rivets、keys etc. The connecting member is small，but it plays the role of passing loads. Characteristic：It can pass general loads and can be dismounted. P P bolt

§2-1连接件的剪切与挤压强度计算 、连接件的受力特点和变形特点: 1、连接件 在构件连接处起连接作用的部件,称为连接件。例如: 螺栓、铆钉、键等。连接件虽小,却起着传递载荷的作用。 螺栓 特点:可传递一般力, P P 可拆卸
