【摘要】：厚板轉(zhuǎn)換層作為高層建筑轉(zhuǎn)換結(jié)構(gòu)的重要形式，可以不受上下軸網(wǎng)布置的限制，能保證轉(zhuǎn)換層上下部分建筑功能的順利實(shí)現(xiàn)，但是由于帶厚板轉(zhuǎn)換層建筑動(dòng)力性能上的劣勢(shì)，使得厚板轉(zhuǎn)換層只能用于低烈度區(qū)，高烈度區(qū)的運(yùn)用較少，而且一般要專(zhuān)項(xiàng)研究之后設(shè)計(jì)施工，因此，研究一種新形式的類(lèi)似板式轉(zhuǎn)換層的結(jié)構(gòu)，該結(jié)構(gòu)不但能解決傳統(tǒng)厚板轉(zhuǎn)換層結(jié)構(gòu)的動(dòng)力性能劣勢(shì)，也能同時(shí)保持厚板轉(zhuǎn)換層本身在建筑功能實(shí)現(xiàn)上的優(yōu)勢(shì)，具有一定的現(xiàn)實(shí)意義。 本文研究的主要內(nèi)容和成果如下： 采用SAP2000軟件建立了帶厚板轉(zhuǎn)換層和帶鋼混組合空腹板轉(zhuǎn)換層的高層建筑模型，進(jìn)行了模態(tài)分析和靜力線性分析，比較分析了兩模型的振型特點(diǎn)、層間剪力分布、層間位移角分布、轉(zhuǎn)換層撓度分布，總結(jié)了鋼混組合空腹板轉(zhuǎn)換層優(yōu)勢(shì)和劣勢(shì)。 通過(guò)7×7組正交分析，，研究了鋼肋梁截面和剪力鍵截面尺寸因素對(duì)帶鋼混組合空腹板轉(zhuǎn)換層建筑的影響，比較了自振周期、振型特點(diǎn)、層間位移、轉(zhuǎn)換層撓度，得出了各因素對(duì)整體結(jié)構(gòu)的影響規(guī)律。 采用振型分解反應(yīng)譜和動(dòng)力時(shí)程分析，分析了轉(zhuǎn)換層豎向錯(cuò)動(dòng)情況，研究了豎向地震作用對(duì)鋼混組合空腹板轉(zhuǎn)換層的影響，得出了符合計(jì)算要求的振型組合方法，豎向錯(cuò)動(dòng)程度及豎向地震作用對(duì)轉(zhuǎn)換層各構(gòu)件內(nèi)力影響。 總結(jié)比較了現(xiàn)今鋼混組合空腹板的計(jì)算方法，通過(guò)一算例，比較分析了有限單元法采用不同計(jì)算單元模型的計(jì)算結(jié)果，給出了有限單元法單元選取建議。 根據(jù)支座連接條件，設(shè)計(jì)出了空腹板網(wǎng)格中間節(jié)點(diǎn)和支座節(jié)點(diǎn)鉸接和剛性連接的構(gòu)造詳圖。
[Abstract]:As an important form of high rise building transfer structure, thick plate transfer layer can not be restricted by the upper and lower axial network arrangement, and can guarantee the smooth realization of the building function of the upper and lower parts of the transfer floor, but because of the disadvantages of the building dynamic performance of the transfer floor with thick slab, So that the thick plate transfer layer can only be used in the low intensity area, the high intensity area is less used, and it is generally necessary to design and construct after special research. Therefore, to study a new type of structure similar to the plate type transfer layer, The structure can not only solve the dynamic performance disadvantage of the traditional thick plate transfer layer structure, but also maintain the advantage of the thick plate transfer layer in the realization of building function, which has certain practical significance. The main contents and achievements of this paper are as follows: the model of high-rise building with thick plate transfer layer and steel-concrete composite empty web plate transfer layer is established by SAP2000 software, and the modal analysis and static linear analysis are carried out. The characteristics of the two models are compared and analyzed, such as the shear force distribution, the displacement angle distribution and the deflection distribution of the transfer layer. The advantages and disadvantages of the transfer layer of the steel-concrete composite fasting plate are summarized. Through 7 脳 7 orthogonal analysis, the influence of the dimensions of steel ribbed beam section and shear bond section on the transfer floor building with steel-concrete composite empty web plate is studied. The natural vibration period, mode characteristics, interstory displacement, deflection of the transfer layer are compared. The influence of various factors on the whole structure is obtained. By using the mode decomposition response spectrum and dynamic time history analysis, the vertical dislocation of the transfer layer is analyzed, the effect of vertical earthquake on the transfer layer of steel-concrete composite hollow plate is studied, and the mode combination method which meets the requirements of calculation is obtained. The degree of vertical dislocation and the effect of vertical earthquake on the internal forces of each component of the transfer layer. This paper summarizes and compares the calculation methods of steel and concrete composite empty web plates. Through an example, the calculation results of finite element method using different calculation element models are compared and analyzed, and some suggestions for the selection of finite element method elements are given. According to the condition of support connection, the structure details of the hinge and rigid connection of the middle node and the support node of the hollow plate mesh are designed.
