钢梁

Finite element model of light-weight steel-concrete composite beams are built up. This element model combines spring element with traditional beam element to form a composite beam element which consists of steel, concrete and springs. The three parts has compatibility of deformation.

2建立了轻钢-混凝土组合梁的非线性有限元分析模型，该模型由传统的梁单元中加入弹簧单元，由钢梁部分、混凝土部分和弹簧三部分在变形协调的基础上组成一个复合梁单元。

The VSR technique is used on trunnion steel girder of arc gate in Liujiadaokou Water Complex Project,which helps meet the requirements for construction period,quality,running security,environmental protection,safe production,etc.

刘家道口枢纽工程弧形闸门支铰钢梁采用了振动时效消应技术，满足了建设工期、质量、运行安全、环保及安全生产等要求。

Workers still are in " bird's nest " coping nervously construction, on original girder structure, the transparent housetop of velar shape already laid very big one part,"Bird's nest " finishing already adjacent 9 into.

工人们还在"鸟巢"顶部紧张地施工，在原有的钢梁结构上，膜状的透明屋顶已经铺设了很大一部分，"鸟巢"完工已经接近九成。

The plastic deformation capacity of the specimens having web openings in plastic zone of the steel beam depends on the reinforcement at beam-to-column connection. The unreinforced specimen could not develop enough ductility, while the specimens reinforced with shear tab or vertical stiffener can achieve satisfactory ductile behavior.

试体於钢梁塑性区腹板开孔，其塑性变形能力则有赖梁柱接头之补强，未补强之试体无法发展出足够之韧性，惟以剪力板或垂直加劲板补强之试体则可发展出令人满意的韧性行为。

You've stepped into a transparent box, one of four that jut 1.3 meters from the tower, hanging from cantilevered steel beams above your head.

你已走进一个透明的小空间，四个小空间自大厦外突1.3公尺，悬挂在头顶的悬臂钢梁上。

This paper give two reinforcement methods of the circular hole castellated beam-castellated beam with full-web extremity and castellated beam reinforced by transverse stiffeners.

提出了两种蜂窝梁的补强方法——端部实腹蜂窝梁和孔边设置横向加劲肋。利用AN SY S程序分析补强前后的圆孔蜂窝钢梁，得出端部实腹梁的受力性能优于设置横向加劲肋的梁的结论

In this paper, the load-displacement and skeleton curve of dendriform connections to the concrete filled square steel rectangular tubes under low-cycle reversed loading was calculated by fiber line element model, which is based on the relation of the stress-strain of steel and concrete and is compared with the FE and experiment.

本文在确定了往复应力作用下钢管混凝土的钢材和核心混凝土的应力－应变关系的基础上，利用纤维杆元模型，有限元模型对钢管混凝土Y形柱和十字形钢梁连接的节点的荷载－位移滞回关系曲线及其骨架曲线进行了计算，并与试验结果进行了比较。

Collapses while landing or placing a load -- most were the result of placing loads on unsecured or unbridged joists.

放置载荷时造成倒塌－主要是将载荷放在没有固定或者支承的钢梁上，造成载荷倒塌。

When connection come into the phase of larger deformations, axial force turn into the tensile force, prevent the further deform, it means that catenaries action occur.

进入大变形阶段后，连接轴向约束压力变为约束拉力，轴向拉力阻止钢梁自身进一步变形，发生了悬链线效应。

With the advances in technology, traffic safety has become more and more emphasized. However, the current passive protection system, such as air bag and steel bar are not merely with high costs. The effectiveness of these safety features are constringed under different conditions.

随著科技的进步，行车安全进一步的被重视，然而现有的被动式保护系统如安全气曩、防撞钢梁等不仅成本高，效果也会因不同的状况而受限。

What would he tell Judith and the children?

他将怎样告诉朱迪丝和孩子们呢？

I this is at that time, the opinion with peacockish true girl is full of in a heart.

这就是当时的我，一个心中布满虚荣的女孩子真实的想法。
