Steel moment-resisting frames with welded beam-to-column connection were traditionally regarded as having excellent performance, and widely adopted in steel constructions, but this opinion changed after the 1994 Northrige earthquake and the 1995 Hyogoken-Nanbu earthquake. These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure. So it can reduce the damage, and is one of the best choices for resisting earthquake.

4Have done a great deal of research work, while on the stiffened ones, Wanget al. [5, 6, 7] have also done a series of research work. But up to now, tothe author's best knowledge, there have been no papers reported in the openliterature on the stability analysis of the laminated composite shells of revo-lution, both unstiffened and stiffened, by the finite element method.

在SABA族元素[1]的基础上，把复合材料各向异性的弹性性质考虑进去，把纵向筋条处理成为空间梁，计入梁偏心的影响，由梁的基本弹性和几何刚度矩阵出发，经过一系列变换，推导出与SABA元素相协调的新的弹性和几何刚度矩阵，从而较为精确地得到了复合材料叠层及加筋的稳定性分析结果。

Considering the influence of other loads and uncertain factors, the follows should be taken into account if the bridge erecting mode is continue to be used.(1) Strengthen beams of steel structure with orbits, especially second half part of the Bere Beam;(2) Altering the space between crossties and increasing the support in the mid of station weight beam both can enlarge the decentralization function of the load carrying on the trunk beam, but usually the latter way is more effective. When the latter way is chosen, the stiffness of the support should be diminished correspondingly. Furthermore, adjusting the height of the support would help a lot in dispersing load.

考虑到其它载荷的影响以及不可预测因素，如继续使用该类架桥方式，应做以下考虑：(1)增加钢架梁与轨道的支撑，特别是在贝雷梁的后半部分；(2)增大荷载作用在箱梁上的分散系数，可适当改变枕木间距，亦可在配重梁的中部增加支撑，后者效果会更有效，当考虑增加支撑时，同时要降低支撑的刚度，支撑如能简单地调整高度，将会对分散载荷起到非常大的帮助。
