Application and development of seismic isolation technique provide a new and effective way for improvement of structure seismic retrofitting 摘要隔震技术的应用和发展为建筑结构抗震能力的提高提供了一条新的行之有效的途径。
In a word , as the first line of defence , the concealed bracings have important effects in the aspects of confining the developing of cracks and increasing integrative seismic capacity 暗支撑作为第一道防线，它在限制裂缝开展提高综合抗震能力中有重要作用。
In recent years . push - over analytical method is regarded as a new evaluation method for seismic resistance capacity of structure in some advanced countries Push - over分析方法是近些年来在国外一些发达国家，如美国、日本受到重视的一种结构抗震能力评价的新方法。
So push - over method can be applied to evaluate bridge structure seismic resistance capacity and damage degree . the influence of p - a effect of bridges is discussed in detail 对一定形式的桥梁结构可以用push - over分析方法进行结构抗震能力评定，其结果准确、可靠。
It ' s been proved by practical engineering abroad to have good accuracy and simplicity . it can save both financial cost and computational time 它将结构静力弹塑性分析与地震反应谱结合起来，是一种简单而有效的结构抗震能力评价工具，目前已经在我国逐渐得到推广应用。
In order to enhance the earthquake - resistant ability of the construction and offer the reference to designers , they put forward the corresponding technical measures to the nonstructural components 对建筑的非结构构件提出了相应的抗震设防技术措施，以提高其抗震能力。
Frame - wall buildings is included . and applying sap2000n finite element analysis program , the analysis of the frame - wall buildings with regular type are completed 同时利用sap2000n大型有限元分析程序对结构进行了空间静力弹塑性分析，对结构的抗震性能和抗震能力作出综合评价。
Therefore , all the ready - made bridges must be urgently analyzed to assess their anti - seismic capacity . the bridges that ca n ' t meet the requirements of ductility must be strengthened 因此，迫切需要对我国既有桥梁的延性抗震能力进行分析，对不满足延性要求的桥梁进行抗震加固。
Augment structure intensity and strongness , the tradition way of building capability of increases resist shock . it gives civil engineering a new life - force 近几年土木工程提出的结构控制设计思想，改变了增大结构强度和刚度来增强建筑物抗震能力传统方法，给土木工程带来了新的生命力。
Since the earthquake resistance of bridge structure and seismic effect are very difficult to be estimated accurately , there are many bridges that have been damaged or collapsed in the earthquake 由于人们尚难准确估计桥梁结构的抗震能力和地震作用，因而，桥梁结构在地震中破坏或倒塌的例子很多。
