The paper is dedicated to study the low-cycle fatigue behavior of a certain semi-rigid connection: the top- and -seat angle.

Then the experimental data of joints of top and seat angle with double web angle are analyzed and load-strain curves of member subassemblages key points are drawn.

为此对双腹板、顶底角钢半刚性节点的试验数据进行分析，绘出试件各组合件关键点的荷载-应变关系曲线。

The change of the seat Angle affects significantly the tangential force, the efficiency of the force, and action efficiency.

To compensate, some manufacturers will even slightly alter the geometry of a commuter cycle, perhaps tilting the seat post at a different angle, but that could potentially lead to shorter riders being forced into a more hunched or horizontal position.
