Analysis And Application Of Seismic Isolation Technique With Irregular Structure

This thesis chooses the irregular structure as the research object. The specific engineering design institute from the actual office building project. Here we are in a certain basis, in theory and simulation software to explore two aspects of these two problems,draw specific conclusions, at the same time summarized. At present, the application scope of isolation technology is constantly expanding, and the layout of the location of the isolation layer has become more flexible. Here we select the reinforced concrete frame structure as the research object, research on base isolation and isolation layer under different isolation effect analysis software. This paper mainly use PKPM and SAP2000 software, analysis of isolation structure the relative linear acceleration in the floor, after the inter layer displacement and inter laminar shear, the comparison of the data base isolation and isolation layer, we structure the location of isolation layer changes on the structure parameters The effect. According to a six layer of irregular frame structure as the engineering background, the source of the project structure design project in the Design Institute, is a frame structure of the office building project design stage. In strict accordance with the norms to select the section size of the slabs, this paper gives a general summary of the development in the first chapter the isolation technology, and then makes a detailed description on the classification of bearings. A detailed overview of this thesis writing ideas, prepare for later writing. In the second and third chapters, we from the modal response spectrum has a thorough analysis of the principle of base isolation and isolation layer. And then establish the model, analysis the difference between the two in the dynamic equilibrium equation of the help down. With the help of PKPM software need to first identify the construction stress component section size in the process of the analysis software And then in the SAP2000 software to compare analysis of acceleration of the two isolated structure, displacement between layers and inter layer shear reference data. And then the comparative analysis of the advantages and disadvantages of the two isolated structure damping performance. Refer to the same two basic cost required, to integrate all kinds of his building price, further comparison of isolation structure cost bring benefits.In a word, through the analysis of the study of this paper, we can get what we want results. It will bring more theoretical research experience to our application later isolated structure, this paper focuses on the irregular structure, so we must establish the irregularbuilding structure. This paper combines the experience of predecessors, and then in the adding their own innovations, such as the time we can add the bearings in PKPM structure design software, and the structure design of SAP2000 were compared. It also solves the reinforcement ratio of SAP2000 in does not comply with the specification of the problem.This is an innovation in this paper is relatively prominent; second, economic analysis in this paper, than in the previous research to be more thorough, the reference design institute of architectural drawings, and then according to the model established, we analyzed all kinds of building materials and a large number of orders Before the needs of the construction cost, economic analysis has laid a solid foundation. The research significance is that we can determine the isolation efficiency of base isolation layer and isolation,selection of appropriate isolation method on the basis of this, for later damping and save cost to prepare. Through a series of analysis, we derive the following conclusion, namely,base isolation has good isolation effect. And inter layer isolation structure has better economic benefits, so the two can perfect unifies in together, in isolation effect and economic benefits to achieve a win-win situation.
