连接螺栓

A nonlinear finite element model is constructed, considering the large deformation, large strain, bolts pretension, bolt contact-slide, as well as material harden and soften, and Miese yield criterions and double nonlinear 3-D element are adopted, so it can predict performance of beam-to-column web connections under cyclic loads.

本文考虑大变形、大应变、螺栓预拉力及螺栓处的接触滑移、材料的强化和软化，采用Mises屈服准则、双重非线性空间单元，建立的非线性有限元模型能够比较精确地模拟梁柱腹板连接在循环荷载作用下的受力性能。

阻力连杆用一个连接装置连接到阻流门并用一个螺栓连接到内部管道上。

Continuous beam models with spring supports were set up to model end-plate connections. By comparing the results from tests with those from model analysis, the following conclusions can be drawn: during loading process, the neutral axis moves from the centroid axis to compression zone, not exceeding the center line of bolts inside the compression flange; ultimately, the tension flange and end-plate can be simplified as T-stub on the assumption that the axial forces of bolts in tension zone are equal to each other.

理论计算系建立带弹性支座的连续梁模型模拟端板连接，将模型计算结果与试验结果比较分析，结果表明：加载过程中，螺栓群中和轴逐渐从其形心轴向受压区移动，但不超过受压翼缘内侧螺栓中心线；极限状态下，受拉翼缘和端板可简化为等效T型件。

分析中，建模时端板与柱翼缘，角钢和T形连接件与柱翼缘和梁翼缘，螺栓头与相邻板件间，螺栓杆与孔壁间都设置了反映边界状态的接触单元。

Results showed that the ductility of bolt spjice is much better than welds, weaker splice joints develop larger plastic deformation, slipping between faying surfaces, bearing of bolts to hole surfaces and buckling of splicing plates are all ideal energy dissipation mechanism.

试验结果表明：螺栓拼接节点的延性远好于梁柱焊缝连接；较弱的拼接节点产生较大的塑性变形；接触面的滑移、螺栓与孔壁的挤压和翼缘拼接板的屈曲都具有良好的耗能能力。
