The assessment formula for shear capacity was established as well, and in which various impact factors of shear strength was considered comprehensively.3. Directed against the main forms of transverse connection in concrete beam bridges, model test and finite element analysis were carried out to find the impact laws of damage on concrete T-beam bridges, in which the three ways of hinged joint, flange rigid connection and cross slab rigid connection were considered. Transverse distribution and degenerate state of transverse connection were studied under various damage conditions. Based on the analysis of test and simulation results, the rule of live load adjustment coefficient of T-beam bridge was put forward, as well as the calculation formula.4. In view of the influence of the damaged transverse connections to load effect, the load effect model was amended by live load adjustment coefficient.

In chapter 3, differing with gonging criterions which use "safety factor" or "reliability indicatrix", the accidents were regarded as a problem of risk. Then probability model was established in ouder to bring out probability of ship collision with bridges and probability of failure due to ship collision with bridges.

在第三章中，与以往的设计规范中结构设计方程所使用的各种"安全系数"、"可靠性指标"等理念不同，本文将船桥相撞事故作为一个风险问题，建立了基于可能性的概率模型，得出了船舶撞击桥梁的概率以及由于船舶撞击致使桥梁结构失效的概率。

The stress distribution of section in wide and thin box girder subjected to simultaneous bending and axial forces doesn't conform to the assumption of the plane section, and the transverse stress distribution is uneven; with the increasing of bridges' span and the lowering of security repertory, to consider the uneven of stress distribution in calculation of design and construction control, and to analyses the shear lag effect in the process of bridges' construction and using are bound to have important engineering value and theorical significances.

在压弯荷载共同作用下，宽而薄箱梁的截面应力分布并不符合平截面假定，沿横向分布不均匀；随桥梁跨度的加大和安全储备的降低，在设计计算和施工控制计算中考虑这种不均匀性，准确分析其在施工和使用阶段的剪力滞问题具有重要的工程价值和理论意义。

The Xiangfu Bridges are three bridges that lie from the east to the west and called CiEn Bridge, DaJue Bridge, PuDu Bridge, and they tell us to bear in mind the grace from Buddhas,teachers, parents and one's motherland, to ultimately derived from full enlightenment by the power of compassion and deliverance

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
