侧梁

At the same time, the cooperation of the multi-layer frame structure is researched with FEA when the pre-stressed threads are stretching, and the relationship between the beam of stretching layer and the beams of nearly layers is discussed. The layout effect of regular reinforcement in the beam on the pre-stressed effective quantities is also analyzed, and the elementary estimation formula of pre-stressing loss on the multi-layer frame is also deduced according to the pre-stressing loss of one-layer pre-stressed frame structure.

同时文中还运用有限元对多层框架结构在预应力张拉过程中，某层梁预应力的张拉与相邻层梁的影响关系和结构各构件的整体协同工作做了研究，分析了非预应力筋在梁中的配置对框架梁预应力有效量的影响；并且在一层框架梁侧限预应力损失的基础上，扩展了多层框架结构中侧向约束引起梁的预应力损失值的初步设计估算公式。

In the thesis the author analyzes the tripping of stiffened panels by three different methods. Based on the above method, the author calculates the ultimate longitudinal strength of a boxlike girder, several ships and many stiffed panels by program. And then checks with some famous experts results. The result is approving. Also the author analyses the reliability of ship considering corrosion. At last an experiment is done to verify the theory.

由于加筋板侧倾屈曲是一种非常危险的破坏形式，本文采用不同方法分析了加筋板侧倾屈曲，并作出了比较；基于上述方法运用计算机程序计算出了箱型梁和几种实船的极限承载能力以及各种加筋板单元的极限强度，并和著名学者的结果进行了比较，结果令人满意；分析了某实船的考虑腐蚀影响的可靠性指标；最后，为了验证理论的精确度，作者参与了钢箱型梁的极限强度试验，通过比较试验数据与理论数据，结果基本一致。

Results: All 8 patients with INVM showed prominent excessive myocardial trabeculation and deep intrabecular. Endocardium of 25 patients with IDCM were smooth, except 2 patients, in which one had excessive myocardial trabeculations in beast apex, the other in lateral wall.

结果：8例INVM均有粗大的肌小梁和小梁间深陷的陷窝，25例IDCM 23例均未见粗大肌小梁及陷窝，1例在心尖部见轻度增粗的肌小梁，另1例在左室侧壁见数目有限的增粗肌小梁，并见其与假腱索相连。

Results Histological investigation showed that the bone trabeculae were disarrayed containing dispersed cartilage cells in the denervated side, whereas the bone trabeculae disarryed orderly with rich blood vessels and no cartilage cell in the control side.

结果 实验侧牵张间隙骨小梁分布方向较杂乱，骨小梁内部有分散的软骨岛分布；对照侧牵张间隙骨小梁主要沿牵张方向分布，血管丰富，成骨细胞活跃。

Fig 1 At the experimental side, two weeks after operation (HE ×100) Many pieces of cartilage cells and spindle-shaped mesenchymal cells were found, by light microscope Fig 2 At the experimental side, twelve weeks after operation (HE ×100) Medullary cavity had formed, which contained hemoblasts and adipocytes, but the trabculae was not typical, by light microscope Fig 3 At the experimental side, twenty-four weeks after operation (HE ×100) The typical cancellous bone had formed, by light microscope Fig 4 At the control side, twenty-four weeks after operation (HE ×100) A large part of CXB was degraded, resorbed and replaced by fibrous tissue, but there was'not any new formed bone, by light mocroscope

图1 实验侧术后2周(HE ×100)镜下可见很多软骨细胞条索和团块生成及大量梭形间充质细胞图2 实验侧术后12周(HE ×100)镜下可见有髓腔形成，内含有造血和脂肪细胞，骨小梁尚不典型图3 实验侧术后24周(HE ×100)镜下可见形成典型的松质骨结构图4 对照侧术后24周(HE ×100)镜下可见大部分CXB被降解吸收，为纤维组织替代，无新骨形成

The elastic supporting forces are regarded as loads and act reversely on longitudinal beams, then the forces acting on longitudinal beams are calculated. Through structure selection, the large rectangular aqueduct bridge with high side beams should be adopted firstly. Because the side beams may reduce the middle beam loads, the span of aqueduct bridge can be increased.

通过结构形式的比较，指出具有大边梁的多纵梁矩形渡槽其侧墙兼做纵梁用，充分利用侧墙刚度大的特点，使横向挡水和纵向承重结合在一起，可以有效地减小水荷载对中纵梁的作用，从而增加渡槽的跨越能力，在大型渡槽的设计中应优先采用。

Torsion would be produced when curve beam under self-weight load, and, torsion and radial force would be produced when structure under prestress load. Such forces would brought prominent side reactions.

在施工阶段和运营阶段，就曾发生过梁体侧向倾覆、支座脱空，墩柱开裂、梁体体侧移以及腹板侧向崩裂等曲线梁结构侧向效应病害，这是技术人员对曲线桥特性把握不够造成的。

In fact, there are a lot of shortcomings such as beams and for larger cross-section of the beam, particularly steel-reinforced self-respect a lot, so the installation of steel beams in the beam must be installed after the end of the template, the beam side of the module should be installed in bars Complete collection experience and qualified after installation.

其实这样有很大的缺点，因为针对与梁截面面积较大的梁，钢筋特别密集，钢筋自重很大，所以在梁钢筋安装必须在梁底模板安装后进行，梁的侧模应在钢筋安装完毕并经验收合格后才安装。

The ZTP II series rubber support is suitable for T girder. it uses the column kneading board and the roof coordination, to make it only carry on longitudinally automatic stepless moved slope, which may avoid the question of the girder list effectively, moreover, ZTP series rubber support because its can adapt the random orientation slope, the bottom of the girder the embedded steel plate does not allow to design the wedge shaped block, therefore specially

ZTPⅡ系列橡胶支座更适用于T型梁，它采用柱面板和顶板的配合，使其只能进行纵向的自动无级调坡，可以有效地避免架梁时的侧倾问题，另外，ZTP系列橡胶支座由于其能适应任意方向的坡度，梁底预埋钢板不许设计楔形块，因此特别适宜于在顶推连续梁上采用。

It sieves the box is board crossbeam riveting hitch welds built-up section By host vice- side bar Hollow beam Enters the material back plate Leaves material board Sieves board and so on composition The side bar selects the low-alloy pressure vessel steel plate The intensity is high The weldability is good Peripheral knee bend And in the vibration direction and along longitudinal connects themulti- roots angle steel Causes the side bar rigidity big enhancement Is advantageous to the intensity enhancement and noise reducing.

其筛箱为板梁铆焊组合结构，由主副侧板、管梁、入料挡板、出料板、筛板等组成，侧板选用低合金压力容器钢板，强度高、可焊性好，周边折弯，并在振动方向及沿纵向联接多根角钢，使侧板刚度大大增强，有利于强度的提高和噪音的降低。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
