偏心连接示例

偏心连接示例(中文5000字,英文20000字)
偏心连接是一种所施加载荷的合力不通过螺栓或焊缝的重心的连接。如果连接具有对称平面，则螺栓或焊缝的剪切区域的质心可以用作参考点，且从荷载作用线到质心的垂直距离称为偏心率。虽然大多数连接可能是偏心加载，但在许多情况下，偏心很小，可能会被忽略。

8.1EXAMPLES OF ECCENTRIC CONNECTIONS
An eccentric connection is one in which the resultant of the applied loads does not pass through the center of gravity of the fasteners or welds. If the connection has a plane of symmetry, the centroid of the shear area of the fasteners or welds may be used as the reference point, and the perpendicular distance from the line of action of the load to the centroid is called the eccentricity. Although a majority of connections are probably loaded eccentrically, in many cases the eccentricity is small and may be neglected. [资料来源：http://doc163.com]
