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。

D1.1 of the AISI Specification limits the maximum longitudinal spacing of connections to ... where smax = maximum permissible longitudinal spacing of connectors L= unbraced length of compression member rI = radius of gyration of I-section about the axis perpendicular to the direction in which buckling would occur for the given conditions of end support and intermediate bracing rcy = radius of gyration of one C-section about its centroidal axis parallel to the web.....

因此，AISI规范第D1.1节限定连接的最大纵向间隙为：，式中 smax =连接体允许的最大纵向间隙 L=抗压构件的自由长度 rI =工字钢对垂直于给定端承和中间肋条件下可能产生纵向弯曲方向的轴的回转半径 rcy =一段U型钢对其平行于筋的质心轴的回转半径。。。。。。。

Experimental Research on FBG Sensor for Large Curvature Detection;2. For large curvature arch, the neutral axis does not pass through the centroidal line of the cross-section, so the moment of inertia is not consistent with the second moment of area.

大曲率拱中，截面形心轴与中性轴不重合，其截面抗弯惯性矩与不考虑曲率影响的截面面积二阶矩有一定的差别；当截面尺寸相对拱弧长来说较大时，此时拱为深拱，剪切变形的影响不能忽略。

The influence of the excursion of the mass center of the torsional vibrating system of the three-string pendulum on the measurement of the moment of inertia is analyzed. A criterion for the mass center of the torsional vibrating system to be in alignment with the central axis of the three-string pendulum and a practical method to measure the moment of inertia of a body about a noncentral axis of mass using the three-string pendulum are proposed.
