抗震

So the calculational results of the formulas are emanative. Avoiding to use the empirical coelfficients are in the analytic process and based on the stress-strain relation between core concrete and steel tube the ultimate bearing capacity and the deformation characteristic of the steel-encased reinforced concrete columns are investigated in this paper. Then the reasonable stress-strain model is given for the further work of the damage analysis of steel-encased concrete and aseismatic ductility.

本文在分析过程中尽可能的避开经验公式，从核心混凝土与钢管的应力-应变关系入手，通过应力协调与应变相容的条件对配有圆钢管的钢骨混凝土构件的极限承载能力与变形性能进行研究，提出合理的应力-应变关系模型，为进一步的钢管混凝土结构损伤、抗震延性分析做好准备工作。

In this paper, By taking Pubugou high rockfill dam on deep overburden as the object of study, the emphatical investigations about the above-mentioned themes have been done as the following aspects.

本文紧密结合这一课题，以瀑布沟深覆盖层上高土石坝为工程对象，重点对高土石坝抗震技术中的关键问题作了如下几方面的研究。

Field reconnaissance was carried out in the epicentral region after the Earthquake.

为了掌握各种类型的砌体结构震害特点，探讨砌体结构的抗震性能，为砌体结构设计规范的修订提供依据，地震发生后，课题组成员长期在现场进行震害调查。

The parameters of Clough-Penzien spectrum related to incident direction, site conditions, intensity, and epicentral distance, were given.

本文还从工程抗震设计的实用角度出发，给出了基于Clough-Penzien谱的与地震波入射方向、场地条件、地震烈度和震中距有关的平稳谱参数取值。

The seismic behavior of great size thin wall reinforced concrete pipe columns is discussed through model experimentations and finite element methods in this paper, after taking Air Cooled Condenser system structure of a main factory building of the large capacity power plant as experimentative prototype.

中文摘要：本文以某大型火电厂空冷凝汽器系统支架结构中的钢筋混凝土管柱为原型，通过模型试验和有限元分析，研究了大尺寸薄壁钢筋混凝土管柱抗震性能等问题。

The results show that fibered reinforced wide-beam frames exhibit large displacement and large damping ratio after yielding of structure.

目前对于扁梁结构的研究还局限于扁梁构件和节点，对扁梁框架抗震性能的研究还未见报道。

Based on the systematic study of fault gouge characteristics (such as minerals component, granulometric composition structure and fractal, maturity, present activity and topotaxy by the SEM), a new way using microscopic and quantitative characteristics of fault gouge is put forward to evaluate the aseismatic problem and the fault resistance problem of concealed fault.

基于断层泥的特征（矿物组分、粒度成分结构和分形、成熟度和目前活动度和SEM特征等）的系统研究，探讨和提出了以断层泥的显微和定量特征来评价隐伏断裂的抗震和抗断难题的新思路和方法，并在镇扬大桥工程区域稳定性评价实际应用中取得了良好的效果，这对建在断裂带上的特大型桥梁工程的稳定性评价具有重大意义。

Then at the fourth component, hysteretic behavior of five different modes was analyzed.

另外，这种节点在更大的荷载作用下也具有很好的延性，说明其抗震性能也不错。

The seismic retrofit included column jacketing, as well as wrapping of the bent cap and bent cap-column joints for confinement, flexural, and shear strength increase.

在抗震加固，包括列护套，以及弯曲的弯曲帽帽和包装柱接头的监禁，弯曲和剪切强度的增加。

Both seismological theory and macroseismic observation show that the shape of strong motion response spectrum depends mainly on magnitude,distance of epicenter and engineering site condition.since it is considered just the effect of engineering site condition and epicenter distance of only site condition to determine the characteristic period of acceleration response spectrum in the antiseismic design criterion of our country at present,the characteristic period of response spectrum determined from those critetion is different from that got from special seismic hazard analysis.

地震学理论和强震观测都表明，强震反应谱的形状主要取决于震级、震中距和场地条件。由于我国现行的各种行业建筑物抗震设计规范中对标准加速度反应谱特征周期Tg作出的规定中一般只考虑场地和震中距的影响或只考虑场地影响，因此在某些情况下，由规范所得到的反应谱特征周期与由专门的地震危险性分析所得到的结果相差较大。
