§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.

§2-1 连接件的剪切与挤压强度计算
一、连接件的受力特点和变形特点:
1、连接件
剪切
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。
特点:可传递一般力,
可拆卸。
