【摘要】：剪力墻結(jié)構(gòu)是通過墻體來承擔(dān)豎向荷載和抵御側(cè)向力的結(jié)構(gòu)體系。其墻體橫截面面積較大，豎向承載力要求相對容易滿足；其結(jié)構(gòu)整體剛度大,側(cè)向變形小，可以較好滿足抗震抗風(fēng)要求；同時(shí)可以節(jié)約建筑物內(nèi)部空間，增大實(shí)際使用面積，故此，剪力墻結(jié)構(gòu)在高層住宅中的應(yīng)用越來越廣泛。 隨著結(jié)構(gòu)形式的日趨復(fù)雜和抗震要求的不斷提高，在高層剪力墻結(jié)構(gòu)設(shè)計(jì)過程中，結(jié)構(gòu)抗震性能的優(yōu)劣和結(jié)構(gòu)設(shè)計(jì)方案的優(yōu)化，一直是設(shè)計(jì)人員關(guān)心的重要問題。同一工程不同的人來設(shè)計(jì)，其設(shè)計(jì)方案不同，抗震性能不同，土建造價(jià)也可能差別很大，有時(shí)會(huì)造成不必要的浪費(fèi)，對此需要進(jìn)行深入細(xì)致的研究。 本文探討了國內(nèi)外高層建筑結(jié)構(gòu)的基本類型和發(fā)展過程。研究了剪力墻結(jié)構(gòu)的各種形式和力學(xué)特點(diǎn)。對西安某高層住宅建筑進(jìn)行了結(jié)構(gòu)設(shè)計(jì)。設(shè)計(jì)了三個(gè)版本的結(jié)構(gòu)方案：第一版方案是短肢剪力墻結(jié)構(gòu)，第二版、第三版方案是不同的普通剪力墻結(jié)構(gòu)，并對三版方案進(jìn)行了詳細(xì)的結(jié)構(gòu)計(jì)算分析。通過三版設(shè)計(jì)方案的計(jì)算結(jié)果和具體表格或曲線圖的直觀描述，以及對幾個(gè)主要參數(shù)：自振周期、頂點(diǎn)位移、最大層間位移角、軸壓比、層間剪力、層間彎矩等的分析和對比，探討了不同方案的可行性、合理性和優(yōu)缺點(diǎn)，分析找出最優(yōu)方案。 本文采用了我國設(shè)計(jì)院普遍采用的有限元分析軟件SATWE，對短肢剪力墻結(jié)構(gòu)、一般剪力墻結(jié)構(gòu)等實(shí)際工程設(shè)計(jì)方案進(jìn)行建模和計(jì)算分析，總結(jié)規(guī)律，提出設(shè)計(jì)建議，得出了一些結(jié)論：①在高烈度震區(qū)，短肢剪力墻數(shù)量需要優(yōu)化，布設(shè)過多會(huì)導(dǎo)致結(jié)構(gòu)抗震性能變差。②普通剪力墻經(jīng)過多次數(shù)量和位置的優(yōu)化，可更好地滿足結(jié)構(gòu)抗震要求。③優(yōu)化后的剪力墻結(jié)構(gòu)，形式合理，剛度適中，建筑材料利用充分，，是高層住宅建筑比較理想的結(jié)構(gòu)形式。
[Abstract]:Shear wall structure is a structure system which can bear vertical load and resist lateral force through wall. The cross section area of the wall is large, the vertical bearing capacity is relatively easy to meet, the overall stiffness of the structure is large and the lateral deformation is small, so it can better meet the requirements of seismic and wind resistance. At the same time, it can save the inner space of the building and increase the practical area. Therefore, the shear wall structure is more and more widely used in the high-rise residence. With the increasing complexity of structural forms and the continuous improvement of seismic requirements, in the design process of high-rise shear wall structures, the merits and demerits of structural seismic performance and the optimization of structural design schemes have always been an important issue of concern to designers. Different people design the same project, its design scheme is different, the seismic performance is different, the civil construction cost may also be very different, sometimes will cause unnecessary waste, need to be studied in depth and meticulous. This paper discusses the basic types and development process of high-rise building structures at home and abroad. Various forms and mechanical characteristics of shear wall structures are studied. The structure of a high-rise residential building in Xi'an is designed. Three versions of the structure scheme are designed: the first version is the short leg shear wall structure, the second edition and the third edition are different common shear wall structures, and the third edition is calculated and analyzed in detail. Through the calculation results of the design plan of the third edition and the visual description of concrete tables or graphs, and the analysis and comparison of several main parameters: natural vibration period, vertex displacement, maximum interstory displacement angle, axial compression ratio, interstory shear force, interstory bending moment, etc. The feasibility, rationality, advantages and disadvantages of different schemes are discussed. In this paper, the finite element analysis software SATWE, which is widely used in our country's design institute, is used to model and calculate the short leg shear wall structure and the general shear wall structure, summarize the rules, and put forward some design suggestions. Some conclusions are drawn as follows: 1 in the high intensity seismic region, the number of short-leg shear walls needs to be optimized, and too much placement will lead to the deterioration of seismic performance of structures. The optimized shear wall structure has the advantages of reasonable form, moderate stiffness and full use of building materials, which is an ideal structural form for high-rise residential buildings.
