Seismic design method of coupling beams with small aspect ratio was one of important problems catching notice at the newly revising structure design codes just completed , and it was discussed seriously at the harmonizing meeting of china code for seismic design of structures , china code for design of concrete structure and the code for design of reinforced concrete high - rise structure . however , because of the insufficiency of experimental research , unanimous opinions were not obtained 在刚完成的我国新一轮结构设计规范修订中，小跨高比连梁的抗震设计方法是被关注的重点问题之一，并在《建筑抗震设计规范》 、 《混凝土结构设计规范》和《高层建筑混凝土结构技术规程》的协调会上作过认真讨论，但因试验研究工作尚不够充分，未能取得一致意见。
According to the theory of optimum aseismic design based on optimal fortification intensity , combining with present code for seismic design of buildings , making use of the method of two - stage minimum - cost design with given seismic intensity , the actual computation of optimal design for aseismic high rising frame structures can be gained 利用考虑最优设防烈度的抗震优化设计理论，与现行抗震设计规范相结合，通过给定地震烈度下二阶段最小造价设计方法，对高层框架结构的优化设计进行实例计算。
On basis of a review of the recent achievements , the distribution of the lateral seismic inertia force along the height of retaining wall and / or bridge abutment , and the calculation of the seismic soil pressure of cohesive backfill are treated with in this paper , for the revision of chinese earthquake resistant design code for highway construction , and a suggestion to combine sei smic design of retaining wall and of bridge abutment together into one chapter from the past in two chapters in the previous version is also worked out 结合规范jtj004 ? 89的修编，本文在总结已有研究成果的基础上，主要研究了挡土墙和桥台地震惯性力沿高度分布的规律，粘性填土的地震土压力计算和计算公式的简化，以及在公路工程抗震设计规范中将挡土墙和桥台的抗震设计归入一章的问题，具体包括如下5项工作。
The earthquake responses of the asymmetric - plan structure are researched and the main factors that influencing the structure ' s response are established . the influences of the earthquake type and the earthquake input in two directions are also researched . the effectiveness of regulation for the irregular rc frames in the code for the seismic design ( gb50011 - 2001 ) is discussed using the flexibility - based fiber - models beam - column elements in the 3d nonlinear analysis program 本文结合国家自然科学基金资助项目“结构非线性地震扭转作用和扭转效应的研究” (项目批准号： 59978055 ) ，对平面不规则结构的地震反应规律进行了深入研究，明确了影响平面不规则结构地震反应的主要结构参数，研究了不同地震动类型和双向水平地震输入对结构扭作用和扭转效应的影响；采用基于有限元柔度法的纤维模型梁柱单元，建立钢筋混凝土框架结构三维非弹性地震反应动力分析程序，对依据我国建筑抗震设计规范( gb50011 - 2001 )设计的不规则结构进行地震反应模拟分析，讨论了现行设计方法的有效性。
This paper firstly compares the provisions about torsion effect and anti - torsion design in several codes ( the old and new chinese code for seismic , and some other countries " codes ) . then , according to the code for seismic design of buildings ( gb50011 - 2001 ) and the code for concrete structure design ( gb50010 - 2002 ) , the paper designs two multi - storied irregular concrete spatial frames , which respectively situated at the area of fortification intensity 8 and 9 . subsequently , using the program based on the column - beam element of fiber model , input several ground motion records , which are selected according to the demand of code , to carry the structures " three - dimensional nonlinear analysis in two perpendicular directions at the same time 本文对比了我国新、旧建筑抗震设计规范（ gb50011 - 2001 、 gbj11 89 ）以及国外设计规范（或指南）中关于结构扭转效应与抗扭设计的相关规定；按照新建筑抗震设计规范和混凝土结构设计规范（ gb50010 2002 ） ，设计了设防烈度分别为8度和9度的两个多层钢筋混凝土不规则空间框架结构，利用纤维模型梁柱单元的三维非线性动力分析程序，根据新抗震设计规范的要求，在设防地震作用和罕遇地震作用水准下选择适当的地震波作为输入，对结构进行了双向地震作用下的三维非线性动力反应分析。
Based above , a two - grade fuzzy comprehensive evaluation model is presented on the ground of the current seismic design code for building . it is that taking the membership of equivalent shear velocity as weight of the model not empirical weight in traditional one - grade model . it has been proved in site classification reasonable 参照我国现行建筑抗震设计规范，改变过去以经验系数为权重的一级模糊综合评判模型，以等效剪切波速对各场地土的隶属度为权重，建立了场地二级模糊综合评判模型，对场地进行划分。
