In this paper, the basic solving process of structural inelastic displacement demand adopting ductility demand spectra is put forward.

结构性能设计的本质就是要求所设计的结构的能力指标大于相应的地震需求指标。

Steel structure is widely used in buildings beacause of the high strenth and ideal ductility of steel.

因为钢材具有很高的强度和很好的延性，钢结构在建筑中被广泛应用。

In this paper the energy dissipation mechanism and anti-earthquake ductility design of ferroconcrete frame structure are expounded mainly.

文章主要阐述了钢筋混凝土框架结构的耗能机理和抗震延性设计的方法。

The experiment makes clear, combine what consolidate can raise ferroconcrete bridge greatly to bear the weight of force and stiffness, test specimen has good ductility.

试验表明，组合加固可以大大提高钢筋混凝土梁的承载力和刚度，试件具有良好的延性。

The results show that dynamical ductil-ity dominated final velocity of fragments. During tube expansion, the shear fracture appears preferentially a-long the adiabatic shear bands under positive stress, so the adiabatic shear band determines the size and shapeof fragments. Though the fragmentation behaviour of medium carbon Si - Mn bainific steel is close to that ofsteel 50SiMnVB, medium carbon Si - Mn bainitic steel is an ideal candidate material for the tubular bombs be-cause it is better in dynamical ductility, which can enable the tubes to gain high speeds before fragmentation.

结果表明：材料动态塑性是决定破片最终速度的主要因素；圆管膨胀时外表面形成以剪切为主的裂纹，并向内扩展，接近内表面的绝热剪切带伴随着圆管的膨胀而扩展，并未出现失稳现象，但在正应力的作用下成为优先的断裂通道、决定破片的尺寸和形态；中碳Si-Mn贝氏体钢与50SiMnVB钢的破碎性能相近，但贝氏体钢动态塑性很更好，破碎前的膨胀量较大、更有利于提高破片初速，是弹箭比较理想的候选材料。

Although ceramics may have good strength and hardness, their ductility, formability, and shock resistance are poor.

虽然陶瓷也许有好力量和坚硬，他们的延展性、formability，和震动抵抗是穷的。

The test results also indicate that separating RC ultra short column into separated columns (shear span to depth ratio higher than 2) by gapping longitudinally at the middle of ultra short column can improve the ductility and deformation capacity of the columns effectively.

不设剪力连接件的SRC超短柱的破坏模式为黏结破坏，与RC超短柱相比，其抗剪承载力和变形能力并无明显提高；设置剪力连接件的SRC超短柱的破坏模式为斜压破坏，其抗剪承载力和变形能力显著提高，但构件的变形能力仍然难以满足现行抗震规范要求。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
