【摘要】：傳統(tǒng)結(jié)構(gòu)抗震通過增強(qiáng)結(jié)構(gòu)本身的抗震性能(強(qiáng)度、剛度、延性)來抵御地震作用,即由結(jié)構(gòu)本身儲(chǔ)存和消耗地震能量,這是被動(dòng)消極的抗震對(duì)策。目前國(guó)內(nèi)外推薦的一些消能減震設(shè)計(jì)方法各有可取之處,但是這些方法均是重理論,輕實(shí)踐；而且我國(guó)規(guī)范對(duì)減震結(jié)構(gòu)的設(shè)計(jì)只是提出了原則性和框架性的規(guī)定,不易操作實(shí)現(xiàn)。因而對(duì)實(shí)際工程的指導(dǎo)意義受到一定限制,對(duì)于一般工程師,更是難以入手操作消能減震結(jié)構(gòu)的設(shè)計(jì),對(duì)不同減震體系的應(yīng)用及工程技術(shù)經(jīng)濟(jì)性對(duì)比更是不足。考慮到以上各方面因素,結(jié)合實(shí)際工程,提出針對(duì)同一工程采用粘滯流體阻尼器及防屈曲支撐兩種不同減震體系的設(shè)計(jì)方法并對(duì)其工程經(jīng)濟(jì)性進(jìn)行對(duì)比分析顯得十分必要,同時(shí)也可以給結(jié)構(gòu)設(shè)計(jì)人員提供一個(gè)參考的依據(jù)。本文對(duì)云南省昆明理工大學(xué)新迎校區(qū)本科教學(xué)實(shí)訓(xùn)中心大樓的設(shè)計(jì)進(jìn)行分析,并采用了兩種不同的減震體系進(jìn)行設(shè)計(jì)分析,經(jīng)過深入的對(duì)比研究,使結(jié)構(gòu)滿足抗震性能設(shè)計(jì)目標(biāo)的要求。研究?jī)?nèi)容如下：1、講述了該課題研究的背景、來源、目的及意義,同時(shí)對(duì)不同減震體系的應(yīng)用現(xiàn)狀進(jìn)行了分析和總結(jié),并重點(diǎn)介紹了粘滯流體阻尼器及防屈曲約束支撐的基本概況。2、以昆明理工大學(xué)新迎校區(qū)本科教學(xué)實(shí)訓(xùn)中心大樓二單元為工程背景,介紹了混凝土結(jié)構(gòu)設(shè)計(jì)的主要內(nèi)容,對(duì)不同結(jié)構(gòu)類型進(jìn)行了分析比較,并對(duì)該本科實(shí)訓(xùn)中心大樓做了基本介紹,包括工程的基本情況、建筑結(jié)構(gòu)安全等級(jí)及設(shè)計(jì)使用年限、自然條件、本工程設(shè)計(jì)遵循的標(biāo)準(zhǔn)、規(guī)范、規(guī)程、設(shè)計(jì)采用的均布活荷載標(biāo)準(zhǔn)值、結(jié)構(gòu)主要材料等。3、介紹了此工程中粘滯流體阻尼器的設(shè)計(jì)及計(jì)算分析。包括：(1)確定工程所采用的消能器類型、阻尼系數(shù)、阻尼指數(shù)、最大出力、最大速度、最大行程、滯回穩(wěn)定性等性能指標(biāo)；(2)介紹粘滯流體阻尼器在此工程中的設(shè)計(jì)方法；(3)用PKPM軟件建模,并對(duì)抗震承載力進(jìn)行驗(yàn)算；(4)對(duì)計(jì)算結(jié)果進(jìn)行分析,做出評(píng)價(jià)。4、介紹了此工程中耗能型屈曲約束支撐的設(shè)計(jì)及計(jì)算分析。包括：(1)不同類型屈曲約束支撐的特性及應(yīng)用范圍的基本介紹；(2)耗能型屈曲約束支撐的設(shè)計(jì)；(3)用PKPM軟件建模,并對(duì)抗震承載力進(jìn)行驗(yàn)算；(4)對(duì)相應(yīng)的計(jì)算結(jié)果進(jìn)行綜合分析,做出全面的評(píng)價(jià)。5、對(duì)比粘滯流體阻尼器及防屈曲支撐這兩種不同的減震體系應(yīng)用在同一新建建筑中帶來的不同影響。從設(shè)計(jì)及施工兩個(gè)方面進(jìn)行對(duì)比分析,對(duì)結(jié)果做出評(píng)價(jià)。6、對(duì)粘滯流體阻尼器及防屈曲支撐這兩種不同的減震體系在本工程中所帶來的工程經(jīng)濟(jì)性進(jìn)行綜合評(píng)價(jià),解決目前最受關(guān)注的安全及經(jīng)濟(jì)性問題,為以后相關(guān)設(shè)計(jì)提供部分依據(jù)。
[Abstract]:Traditional structures resist seismic action by enhancing their seismic performance (strength, stiffness, ductility), that is, storing and consuming seismic energy by the structure itself. This is a passive and passive anti-seismic countermeasure. At present, some design methods of energy dissipation and seismic absorption recommended at home and abroad have their own merits, but these methods are all theoretical and light to practice. Moreover, the design of seismic absorption structure in our code only puts forward the rules of principle and frame, which is not easy to operate. Therefore, the guiding significance of practical engineering is limited to general engineers. It is difficult to operate the design of energy dissipation structure, and the application of different damping system and the comparison of engineering technology and economy are even more insufficient. Considering the above factors, combined with the actual engineering. It is necessary to put forward two design methods for the same project using viscous fluid damper and buckle-proof bracing, and compare and analyze the engineering economy of the two systems. At the same time, it can also provide a reference for the structural designers. This paper analyzes the design of the undergraduate teaching training center building in the new campus of Kunming University of Technology, Yunnan Province. Two different damping systems are used for design and analysis. Through in-depth comparative study, the structure can meet the requirements of seismic performance design. The research contents are as follows: 1, the background of the research is described. At the same time, the application status of different damping systems is analyzed and summarized, and the basic overview of viscous fluid dampers and buckle-restrained braces is introduced in detail. This paper introduces the main contents of concrete structure design and analyzes and compares the different structure types with the engineering background of two units of the building of the undergraduate teaching practice training center in the new campus of Kunming University of Technology. At the same time, the author introduces the building of the undergraduate training center, including the basic situation of the project, the safety grade of the building structure and the design life, the natural condition, the standard, the specification and the regulation of the project design. This paper introduces the design and calculation of viscous fluid damper in this project, including the determination of the type of energy dissipator used in the project.
