【摘要】：隨著經(jīng)濟(jì)發(fā)展和建筑工程技術(shù)的成熟,各種類型的結(jié)構(gòu)體系迅速發(fā)展,結(jié)構(gòu)選型的研究日益被大家所重視。隨著房價的日益攀升,人們除注重房屋的質(zhì)量外,也注重它的經(jīng)濟(jì)性能,不管是對于投資者或者是個人都希望房屋能夠物美價廉,綜合考慮經(jīng)濟(jì)因素,使得結(jié)構(gòu)目標(biāo)效益最大化成為結(jié)構(gòu)選型研究的當(dāng)務(wù)之急。 本文以高層建筑結(jié)構(gòu)中比較典型的某二十層的高層單塔建筑結(jié)構(gòu)為選型實例,探討了高層建筑結(jié)構(gòu)選型的發(fā)展趨勢及影響因素,提出了高層建筑結(jié)構(gòu)選型中常用的幾種結(jié)構(gòu)體系及其優(yōu)缺點和適用范圍,分析了高層建筑結(jié)構(gòu)選型的主要控制指標(biāo)如水平荷載、軸向變形、側(cè)向位移、結(jié)構(gòu)延性、地震作用、結(jié)構(gòu)延性等。 本文選用高層建筑選型中常用結(jié)構(gòu)形式中的純剪力墻結(jié)構(gòu)、框架—剪力墻結(jié)構(gòu)、框架—核心筒結(jié)構(gòu)這三種結(jié)構(gòu)形式,運(yùn)用于該選型實例進(jìn)行建模計算來對比這三種結(jié)構(gòu)形式的周期、內(nèi)力、位移等指標(biāo),對比分析結(jié)構(gòu)整體受力性能,從而找出相對適合二十層左右單塔建筑的合理體系,根據(jù)三種結(jié)構(gòu)形式的施工圖來采用廣聯(lián)達(dá)預(yù)算軟件,計算出各種結(jié)構(gòu)形式所用的混凝土及鋼筋含量指標(biāo),分析對比各種結(jié)構(gòu)形式的經(jīng)濟(jì)性能選出經(jīng)濟(jì)最優(yōu)方案,結(jié)合受力及經(jīng)濟(jì)綜合分析考慮三種結(jié)構(gòu)體系找出最優(yōu)方案,使得滿足受力前提下結(jié)構(gòu)經(jīng)濟(jì)性能最優(yōu),為今后此種結(jié)構(gòu)的設(shè)計工作提供參考依據(jù)。
[Abstract]:With the development of economy and the maturity of construction technology, various types of structural systems are developing rapidly, and the study of structural selection has been paid more and more attention. With the rising housing prices, people pay attention not only to the quality of houses, but also to their economic performance. Whether it is for investors or individuals, they hope that houses will be good and cheap, and that economic factors will be taken into account. It is urgent to maximize the benefit of structural target in the study of structural selection. In this paper, the development trend and influencing factors of high-rise building structure selection are discussed by taking the typical high-rise single-tower structure of a 20-story structure as an example. This paper puts forward several kinds of structural systems commonly used in the selection of tall building structures and their advantages, disadvantages and applicable scope, and analyzes the main control indexes of the selection of tall building structures, such as horizontal load, axial deformation, lateral displacement, structural ductility, seismic action, etc. Structural ductility, etc. In this paper, three kinds of structural forms, such as pure shear wall structure, frame-core tube structure, which are commonly used in high-rise building selection, are selected. Using this model selection example to compare the cycle, internal force, displacement and other indexes of the three structural forms, and compare and analyze the overall mechanical performance of the structure, and find out the reasonable system which is relatively suitable for the 20-story single tower building. According to the construction drawings of three kinds of structural forms, the Wide-Union budget software is used to calculate the concrete and reinforcement content indexes used in various structural forms, and to analyze and compare the economic performance of various structural forms to select the economic optimum scheme. Considering the three structural systems, the optimal scheme can be found by combining the stress analysis and the economic comprehensive analysis, which makes the economic performance of the structure optimal under the condition of the stress, and provides a reference for the design work of this kind of structure in the future.
