Shaking table test is an important method to study earthquake resistance of engineering structures.

振动台模型试验是研究工程结构抗震的重要手段之一。

Structural analysis and shaking table test show that the prospective performance objectives of earthquake-resistance can be achieved.

结构分析和模型试验结果均表明，该结构可以达到预期的抗震性能目标。

Nature frequency and earthquake response of the structure are determined through shaking table test.

通过振动台试验，确定了模型的自振频率，多种地震波输入下的结构加速度反应和位移反应，对结构的抗震性能进行了综合评定。

In order to improve the earthquake emergency rescuing efficiency and to lift city safety and capability of sustainable development, there is a vital importance and practical significance for the research of pre-disaster-planning of traffic system.

因此，开展城市交通系统抗震防灾规划研究，提高地震应急救援效率，对于提升城市安全和可持续发展能力，具有重要的现实意义。

Take the 260m Nuozhadu high core rock-fill dam for example, a new idea of safety evaluation based on the criterion of deformation is proposed.

以260m高的糯扎渡心墙土石坝为例，初步发展了基于地震永久变形控制标准的高土石坝抗震安全评价思想。

Many studies on the behavior of beam-column connections used in steel moment resisting frame and their effect on seismic behavior of steel frames have been carried out.

地震后人们对钢框架梁柱连接性能及其对钢框架结构抗震性能的影响进行了大量研究。

Due to moment resisting connections are made in both directions in steel frames, so beam-to-column web connections are generally as flange connection. The construction and performance under load of web connections are different from flange connections, and there are more difficulties for theory analysis and design. Studies on mechanism of beam-to-column web connections under cyclical load are not only significant to the theoretical research, but also important in practice.

钢结构框架一般纵横两个方向均为框架，梁柱腹板连接非常普遍，构造和受力性能与翼缘连接不同，而且理论分析和设计更为困难，研究钢框架梁柱腹板连接在循环荷载作用下的受力性能和破坏机理并提出抗震设计对策，具有重要的理论意义和重大的工程应用价值。

Adding supplemental shear panels to the traditional moment resisting frame can enhance the system stiffness, strength and ductility capacities.

传统抗弯构架加入耐震间柱后可使刚度、强度与韧性获得提升，因此可设计为新建筑的抗震系统或既有建筑的补强。

2Shear deformation of joint and second order effect would increase failure probability , and decrease seismic resistance reliability of steel frame.

2结构的二阶效应和节点的剪切变形会增大结构发生各种破损的概率，降低结构的抗震可靠度。

Background, basic conception and basic theory frame of earthquake resistance design of building structure were briefly introduced, based on performance.

近十年先后在美国、日本、土耳其、印度、中国的台湾省发生破坏性地震，特别是美国(1994年，Northridge)和日本(1995年，阪神)发生的强烈地震对生命财产造成巨大损失，引起各国政府和社会各方面的广泛关注，也引起各国地震工程学者的高度重视，促使地震工程学者反思现行结构设计体系，现有的抗震设计理论无论其本身还是它在适应社会的需求方面都存在不足之处。
