The pre - stressed anchor supporting structure with beam and column is analyzed theoretical in this paper , combined with theoretical study and design of such supporting structure , which is one of the plan projects of construction science and technology in hunan province . the topic provides engineering aiming with practical and concise computation method , and also provides the advice for structure with proper theory foundation and schemes to some extent 本文结合湖南省建设科技计划项目“永久性肋梁柱锚杆挡土墙设计关键问题及计算软件开发” ,对预应力肋梁柱锚杆支挡结构进行了理论分析,提供了适合于工程的、比较简捷的实用计算方法,同时也为该类支挡结构设计提供一定的理论依据和设计建议。
Based on the elastic michanics and plastic michanics , using the finit element analyses , the nonlinear finit element model of the beam - to - column is established in which the dynamic hardening and lardge deforamation are taken into account . the response of beam - to - column connections under cyclic load is researched on . after comparing between the finite element analyses and the experimental result through which the fem is verifid , three series of welded joins under cyclic load are computed 本文首先将有限元分析结果与现有试验结果对比，验证了分析方法的正确性，然后对三个系列的焊接梁柱连接在循环荷载作用下进行了计算分析，比较了全焊连接与栓焊混合连接的性能，研究了钢材屈服强度、屈强比、焊接孔形状及大小对全焊梁柱连接的影响，提出了梁柱连接设计建议。
So the topic for farther discussion will be developed on the ground of soil - foundation - structure interactions , and emphasizes particularly on the investigation for dynamic effects on interaction of pile - supported structures subjected to lateral seismic load at layered - soil media . by use of theoretical analysis and test research , this dissertation tries to identify the dynamic interaction mechanism of soil - foundation - superstructure and it will provide engineering application with practical , and also offer theoretical basis and design suggestion for seismic design of dynamic soil - pile - superstructure interaction . the article is divided into seven chapters , as follows : 1 本文工作将围绕地基-基础-上部结构共同作用这一课题作进一步探讨,侧重于水平地震作用下成层地基中的桩基-建筑物的动力相互作用特性研究,试图通过理论分析和试验研究,认识地基-基础-上部结构动力相互作用机理,为实践应用提供指导,亦为考虑成层地基-桩基-上部结构动力相互作用的抗震设计提供一定的理论依据和设计建议。
After two decades ' research and engineering practices on concrete structures with large longitudinal length by prestressed engineering institute of southeast university , some key technical problems concerned by engineers are explained , and corresponding suggestions are given , which can be referred for design 摘要通过东南大学预应力工程研究所近20年对超长混凝土结构设计中所涉及的基本问题进行的基础研究及国内几十项工程的实践，针对设计中工程技术人员关心的关键技术问题给出相应的解释，并提出了相应的设计建议，以供超长混凝土结构设计参考。
Some suggestions are made based on the results of this research and the shortcoming of " technical specification for application of geosynthetics in highway " , geogrids should be overlapped on the slope . much greater importance should be attached to slope protection and drainage system design . if necessary , checking computations of foundation bearing capacity should be done 结合本文研究成果及我国现行规范中的不足，提出了设计建议：土工格栅在边坡处应进行反包施工，以提供足够的锚固力；应做好坡面防护和排水设计；必要时对地基承载力进行验算。
On the basis of the experimental research , its hysteresis characteristics , calculation method of stiffness in different stage and ultimate bearing capacity are discussed . based on a seismic design method on the new lateral resistant system is concluded according to the research result in the paper . the effect of some parameters is discussed on steel frame with cavity sandwich wall infill and some design suggestion is presented 在试验研究的基础上，建立了该体系的恢复力特性模型，提出了模型各受力阶段的刚度计算公式、极限承载能力的计算方法和抗震计算方法；对影响空腔结构砌体填充墙钢框架抗侧力性能的因素进行了讨论，提出了设计建议。
