【摘要】：目前，地下室結(jié)構(gòu)在高層建筑結(jié)構(gòu)中已得到廣泛的應(yīng)用，但是帶地下室高層建筑結(jié)構(gòu)的設(shè)計(jì)和理論還存在著尚未解決的問題，例如如何考慮回填土的約束作用、嵌固部位的選取等。另外，實(shí)際結(jié)構(gòu)的地下室設(shè)置情況不盡相同，地下室側(cè)壁對(duì)塔樓結(jié)構(gòu)的約束作用也不相同，引起豎向構(gòu)件在地下室頂板上下層的剪力的變化情況尚不明確。本文通過對(duì)大量文獻(xiàn)資料進(jìn)行整理、分析和研究，在理論公式推導(dǎo)的基礎(chǔ)上，著重討論分析了影響豎向構(gòu)件在地下室頂板上下層剪力傳遞的主要因素，并采用有限元分析方法探討了不同結(jié)構(gòu)體系的豎向構(gòu)件在地下室頂板上下層剪力傳遞的情況。本文主要內(nèi)容為： 1、通過閱讀大量現(xiàn)有文獻(xiàn)及相關(guān)工程設(shè)計(jì)資料，重點(diǎn)闡述了帶地下室高層建筑結(jié)構(gòu)設(shè)計(jì)中尚存在的問題，最終確定了本文的研究方向；同時(shí)通過對(duì)現(xiàn)有分析方法和軟件的評(píng)價(jià)，確定了后續(xù)分析中采用的分析手段和有限元軟件。 2、在結(jié)構(gòu)力學(xué)的基礎(chǔ)上，推導(dǎo)出彈性桿在地下室位置的剪力與在首層位置的剪力的比值的表達(dá)式，并討論了可能影響該表達(dá)式的因素； 3、建立平面框架模型，針對(duì)三種不同的地下室設(shè)置情況，討論了框架柱在地下室位置的剪力與在首層位置的剪力之間的關(guān)系； 4、建立剪力墻結(jié)構(gòu)、框架剪力墻結(jié)構(gòu)、框支剪力墻結(jié)構(gòu)和框架核心筒結(jié)構(gòu)的有限元模型，采用PKPM和ETABS進(jìn)行計(jì)算，，分析各結(jié)構(gòu)體系的豎向構(gòu)件在地下室頂板上下層的水平剪力傳遞情況； 5、評(píng)價(jià)理論分析和有限元分析的結(jié)果，歸納出豎向構(gòu)件在地下室頂板上下層的剪力傳遞規(guī)律，為實(shí)際工程設(shè)計(jì)提供參考。
[Abstract]:At present, basement structure has been widely used in high-rise building structure, but there are still some unsolved problems in the design and theory of high-rise building structure with basement, such as how to consider the constraint of backfill. In addition, the actual structure of the basement settings are not the same, the basement side wall of the tower structure constraints are not the same. It is not clear that the shearing force of the vertical members in the upper and lower floors of the basement roof is not clear. In this paper, a large number of documents are sorted out, analyzed and studied, and based on the theoretical formula derivation. The main factors affecting the shear transfer of vertical members in the upper and lower floors of the basement roof are discussed and analyzed emphatically. The shear transfer of vertical members of different structural systems in the upper and lower floors of basement roof is discussed by using finite element analysis method. The main contents of this paper are as follows: 1. By reading a large number of existing documents and related engineering design materials, the problems in the structural design of high-rise building with basement are expounded, and the research direction of this paper is finally determined. At the same time, through the evaluation of the existing analytical methods and software, the analysis means and finite element software used in the follow-up analysis are determined. 2. On the basis of structural mechanics, the expression of shear force ratio between the position of elastic rod in the basement and the shear force in the first floor is derived, and the factors that may affect the expression are discussed. 3. The plane frame model is established, and the relationship between the shear force of the frame column in the basement position and the shear force in the first floor position is discussed. 4. The finite element models of shear wall structure, frame shear wall structure, frame-supported shear wall structure and frame-core tube structure are established and calculated by PKPM and ETABS. The horizontal shear transfer of the vertical members of each structural system in the upper and lower floors of the basement roof is analyzed. 5. The results of theoretical analysis and finite element analysis are evaluated, and the shear transfer law of vertical members in the upper and lower floors of basement roof is summarized, which provides a reference for practical engineering design.
