【摘要】：本论文选取了不规则的结构作为研究对象。具体的工程来源于设计院实际的办公楼项目。在这里我们在一定的基础上,在理论与软件模拟两个方面来探讨这两个问题,得出具体的结论,同时进行总结。当前,隔震技术的应用范围正在不断的扩大,同时隔震层的位置布置也变得比较灵活。在这里我们选择钢筋混凝土框架结构作为研究对象,研究了在基础隔震与层间隔震情况下的不同的隔震效果。本文主要使用的分析软件为PKPM与SAP2000软件,在线性分析隔震结构的楼层相对加速度、层间位移以及层间剪力之后,对比基础隔震与层间隔震的有关数据,我们结构隔震层位置变化对结构有关参数的影响。本文以一个六层不规则框架结构作为工程背景,该项目来源于设计院的结构设计项目,是一个框架结构的办公楼项目。设计阶段严格按照规范来选取各受力构件的截面尺寸,本文在第一章对隔震技术的发展进行了总的概括,然后就隔震支座的分类作了细致的描述。对本论文的写作思路进行了详细的概述,为后期的论文写作做好前期的准备。在第二和第三章节,我们对从振型反应谱方面透彻分析了基础隔震以及层间隔震的原理,然后建立相关的模型,在动力平衡方程的帮助下来分析这两者之间的区别。论文软件分析过程中需要借助PKPM软件来首先确定建筑受力构件的截面尺寸,然后在SAP2000软件中来对比分析这两种隔震结构的加速度、层间位移以及层间剪力等参考数据。然后对比分析这两种隔震结构减震性能的优劣。同时参考二者的基本造价要求,综合各种各样他的造价,进一步对比二者对隔震结构造价带来的益处。总而言之,通过本论文的研究分析之后,我们最终可以获取我们想要的成果。这也会给我们后期隔震结构的应用带来更多的理论研究经验,本论文着眼于不规则结构,所以必须建立不规则的建筑结构。本论文综合了前人的经验,然后在其中加入了自己的创新点,例如本次我们可以在PKPM结构设计软件中添加隔震支座,将其与SAP2000中的结构设计进行对比。这也进一步解决了SAP2000中钢筋配比不符合规范的问题。这是本文相对突出的一个创新点;其次,本文中的经济性分析比前人研究的更为透彻,参考设计院的建筑图,然后再根据自己建立的结构模型,我们大量分析了各种建筑材料以及目前施工需要的费用,为经济性分析打下了坚实的基础。本论文的研究意义在于我们可以判断基础隔震与层间隔震的隔震效益,在此基础上选取合适的隔震手段,为后期的减震以及节省造价做准备。通过一系列的分析,我们得出以下结论,即基础隔震具有更好的隔震效果。而层间隔震结构具有更好的经济效益,所以二者可以完美的结合在一起,在隔震效果与经济效益方面实现共赢。
[Abstract]:This paper selects irregular structure as the research object. The concrete project comes from the actual office building project of the design institute. Here we are on a certain basis. In theory and software simulation to explore these two problems, draw concrete conclusions, and summarize. At present, the application of isolation technology is expanding. At the same time the location of the isolation layer has become more flexible. Here we choose reinforced concrete frame structure as the research object. This paper studies the different isolation effect in the case of base isolation and interstory isolation. In this paper, the main analysis software is PKPM and SAP2000, and the relative acceleration of the isolated structure is analyzed linearly. After the interstory displacement and the interstory shear force, the relative data of the base isolation and the interstory isolation are compared. In this paper, a six-story irregular frame structure is used as the engineering background. The project comes from the structural design project of the design institute. It is an office building project with frame structure. In the design stage, the section size of each bearing member is selected strictly according to the specifications. In the first chapter, the development of isolation technology is summarized. Then, the classification of the isolation bearings is described in detail. The writing ideas of this paper are summarized in detail, and the early preparation for the later writing is made. In the second and third chapters. We have thoroughly analyzed the principle of base isolation and interstory isolation from the aspect of mode response spectrum, and then established the relevant model. With the help of the dynamic equilibrium equation, the difference between the two is analyzed. In the process of the software analysis, we need to use PKPM software to determine the cross-section size of the structural members. Then the acceleration of the two isolation structures is compared and analyzed in SAP2000 software. The reference data, such as interstory displacement and interstory shear force, are compared and analyzed. At the same time, the basic cost requirements of the two kinds of isolated structures are compared and analyzed. At the same time, a variety of their cost is synthesised. Further compare the benefit of the two to the cost of isolation structure. In a word, through the research and analysis of this paper. Finally, we can obtain the desired results. This will also bring us more theoretical experience in the application of seismic isolation structures. This paper focuses on irregular structures. Therefore, we must establish irregular building structure. This paper synthesizes the previous experience, and then adds its own innovation, for example, we can add the isolation support in the PKPM structure design software. Compare it with the structural design in SAP2000. This further solves the problem that the ratio of steel bar in SAP2000 does not conform to the specification. This is a relatively outstanding innovation point in this paper; Secondly, the economic analysis in this paper is more thorough than the previous research, referring to the architectural drawings of the design institute, and then according to their own structural model. We have analysed a wide range of building materials and the current cost of construction. The research significance of this paper is that we can judge the isolation benefit of base isolation and interstory isolation, and on this basis select the appropriate isolation means. Through a series of analysis, we draw the conclusion that the base isolation has better isolation effect, and the interstory isolation structure has better economic benefit. So the two can be perfectly combined, in isolation effect and economic benefits to achieve win-win.
