【摘要】：我國(guó)頻頻發(fā)生高震級(jí)的地震,給我國(guó)造成了巨大的損失。當(dāng)建筑結(jié)構(gòu)遭遇地震時(shí),由于結(jié)構(gòu)自身抗震能力差導(dǎo)致了人員傷亡嚴(yán)重。結(jié)構(gòu)耗能減震技術(shù)的提出能夠提高結(jié)構(gòu)自身的抗震性能,其主要應(yīng)用于高層及超高層建筑中更加符合我國(guó)建筑行業(yè)的發(fā)展趨勢(shì)。本文將根據(jù)結(jié)構(gòu)耗能減震技術(shù)的自身特點(diǎn),對(duì)其在高層建筑結(jié)構(gòu)中的經(jīng)濟(jì)性進(jìn)行綜合評(píng)價(jià)。首先,本文對(duì)結(jié)構(gòu)耗能減震技術(shù)的基本理論進(jìn)行了論述,介紹了結(jié)構(gòu)耗能減震技術(shù)國(guó)內(nèi)外發(fā)展?fàn)顩r。并且研究了結(jié)構(gòu)振動(dòng)控制理論,其中結(jié)構(gòu)耗能減震技術(shù)屬于最經(jīng)常用的被動(dòng)控制,主要工作原理是通過(guò)附加的減震裝置來(lái)控制結(jié)構(gòu)振動(dòng)。隨后,介紹了新型合金阻尼器,該阻尼器是結(jié)構(gòu)耗能減震技術(shù)中較為有代表性的一種,為后文中引入采用新型合金阻尼器的減震項(xiàng)目經(jīng)濟(jì)評(píng)價(jià)作為案例奠定基礎(chǔ)。其次,本文根據(jù)結(jié)構(gòu)耗能減震技術(shù)自身的特性,參考了許多目前已有的經(jīng)濟(jì)評(píng)價(jià)指標(biāo)體系,并建立了高層建筑結(jié)構(gòu)耗能減震技術(shù)經(jīng)濟(jì)性評(píng)價(jià)指標(biāo)體系。該指標(biāo)體系從經(jīng)濟(jì)效益評(píng)價(jià)、安全性能評(píng)價(jià)、社會(huì)效益評(píng)價(jià)三個(gè)方面評(píng)價(jià)和探討了結(jié)構(gòu)耗能減震技術(shù)的經(jīng)濟(jì)性。在這個(gè)評(píng)價(jià)指標(biāo)體系中設(shè)置了三個(gè)層次的評(píng)價(jià)指標(biāo),其中有三個(gè)一級(jí)評(píng)價(jià)指標(biāo),七個(gè)二級(jí)指標(biāo)和二十四個(gè)三級(jí)評(píng)價(jià)指標(biāo)。然后,再仔細(xì)分析了這些評(píng)價(jià)指標(biāo)的內(nèi)涵和計(jì)算方法后,本文對(duì)常用的數(shù)學(xué)評(píng)價(jià)方法進(jìn)行了綜合的分析、對(duì)比和研究了,最終擇優(yōu)選擇了DEA評(píng)價(jià)方法并構(gòu)建了高層建筑結(jié)構(gòu)耗能減震技術(shù)經(jīng)濟(jì)性評(píng)價(jià)模型。由于本文中的指標(biāo)有定性和定量指標(biāo)兩種指標(biāo),本文采用了專家打分法對(duì)定性指標(biāo)進(jìn)行賦值,然后使用了均值法進(jìn)行無(wú)量綱處理。由于評(píng)價(jià)指標(biāo)較多,采用主成分提取的方法進(jìn)行了指標(biāo)的篩選。最后應(yīng)用了交叉DEA評(píng)價(jià)模型,對(duì)實(shí)際的結(jié)構(gòu)減震項(xiàng)目的經(jīng)濟(jì)性做出了評(píng)價(jià),并驗(yàn)證了已建立的指標(biāo)體系的有效性和評(píng)價(jià)模型是正確的,對(duì)于工程相關(guān)新技術(shù)的經(jīng)濟(jì)評(píng)價(jià)研究具有較好的參考和應(yīng)用意義。最終,得到結(jié)論為：在抗震設(shè)防地區(qū),應(yīng)用減震技術(shù)的項(xiàng)目的經(jīng)濟(jì)性明顯優(yōu)于傳統(tǒng)抗震設(shè)計(jì)的項(xiàng)目；該地區(qū)的地震設(shè)防烈度越高,其經(jīng)濟(jì)性的優(yōu)勢(shì)越明顯。
[Abstract]:High-magnitude earthquakes occur frequently in China, causing huge losses to our country. When the building structure is subjected to earthquake, the poor seismic capacity of the structure results in serious casualties. The structure energy dissipation and seismic absorption technology can improve the seismic performance of the structure itself, and its main application in high-rise and super-tall buildings is more in line with the development trend of the construction industry in China. In this paper, according to the characteristics of energy dissipation and seismic absorption technology of structures, the economy of high-rise building structures is comprehensively evaluated. Firstly, the basic theory of structure energy dissipation technology is discussed, and the development of structure energy dissipation technology at home and abroad is introduced. The structure vibration control theory is also studied. The structure energy dissipation and damping technology is the most frequently used passive control. The main working principle is to control the structure vibration through the additional shock absorber. Then, a new alloy damper is introduced, which is a representative of the structural energy dissipation technology, which lays a foundation for the economic evaluation of the shock absorber project using the new alloy damper as a case study. Secondly, according to the characteristics of energy dissipation and seismic absorption technology of structures, this paper refers to many existing economic evaluation index systems, and establishes the economic evaluation index system of energy dissipation technology for high-rise building structures. This index system evaluates and discusses the economy of structure energy dissipation and seismic absorption technology from three aspects: economic benefit evaluation, safety performance evaluation and social benefit evaluation. In this evaluation index system, there are three evaluation indexes, including three first-grade evaluation indexes, seven second-class indexes and twenty-four third-level evaluation indexes. Then, after careful analysis of the connotation and calculation methods of these evaluation indexes, this paper makes a comprehensive analysis, comparison and research on the commonly used mathematical evaluation methods. Finally, the DEA evaluation method is selected and the economic evaluation model of energy dissipation technology for high-rise building structures is constructed. Because there are two kinds of qualitative and quantitative indexes in this paper, the expert scoring method is used to assign the qualitative index, and then the mean method is used to deal with the dimensionless index. Because there are many evaluation indexes, the method of principal component extraction is used to screen the indexes. Finally, the cross-DEA evaluation model is applied to evaluate the economy of the actual structural shock absorber project, and the validity of the established index system and the evaluation model are proved to be correct. It has good reference and application significance for the economic evaluation of new engineering related technologies. Finally, it is concluded that in the seismic fortification area, the economic efficiency of the project using the seismic absorption technology is obviously superior to that of the traditional seismic design project, and the higher the seismic fortification intensity in this area, the more obvious the economic advantage of the project.
