【摘要】：這些年,繁榮的高層結構形式種類繁多、日新月異,高層呈高速發(fā)展狀態(tài)。其中,在浩瀚如海的各色各樣建筑形式里,帶轉換層的高層建筑結構是比較優(yōu)秀的一種。轉換層不僅僅滿足了使用效用的要求,而且完成了不同上下層結構形式的完美過渡。轉換層大致分為以下幾種:梁式轉換層、板式轉換層、箱形式轉換層、桁架式轉換層等等。其中,梁式轉換層在世界范圍內得到普遍采用的益于其傳力路徑清晰明了、受力形式不復雜等優(yōu)異性能。然而,傳統(tǒng)的鋼筋混凝土梁式轉換層自重過大、施工困難等缺陷使新型材料的梁式轉換層結構得到快速發(fā)展并受到好評與青睞。目前,那些高層建筑結構采用新型材料的梁式轉換層的系統(tǒng)深入的抗震性能研究對于實際工程應用具有非常重且深遠的意義。本文將一棟高層建筑結構采用鋼骨混凝土作為梁式轉換層做數值模擬,分析內容如下:1)對于在目前設計規(guī)范和概念分析中的帶轉換層高層建筑結構的關聯(lián)設計做系統(tǒng)的探討。并且對帶轉換層高層建筑結構發(fā)展至今的抗震分析方法理論以及鋼骨混凝土梁式轉換層在國內外的發(fā)展情況進行分析研究。2)由不同的轉換層位置進行不同取值,使用SAP2000對由于不同轉換層位置而引起的不同框架剪力墻結構進行建模,然后給這些不同的結構模型做精細的反應譜分析和模態(tài)分析,從每個計算方案的振型、內力分布曲線、每個樓層的層間位移角、結構頂點的位移等諸多方面對其抗震性能進行對比分析,探討這個因素給該類型結構處于彈性階段時對抗震性能的作用。3)由不同的轉換層上下剛度比進行不同取值,使用SAP2000給由于不同的轉換層上下剛度而引起的不同框架剪力墻結構做方案的建立,然后給這些不同的結構方案做模態(tài)分析和反應譜分析,從每個計算方案的振型、建筑頂點的位移、每個樓層的層間位移角及內力分布曲線等諸多方面給其抗震性能做對比分析,分析這個因素給該類型建筑處于彈性階段時抗震性能的作用。4)采用Pushover給建筑不同取值的方案模型做在多遇地震影響時和罕遇地震影響時的靜力彈塑性分析,通過性能點、加載步數、最大層間位移角和塑性鉸得出現(xiàn)狀態(tài)等參數完善結構在地震作用下的反應能力。通過對不同轉換層位置結構、不同轉換層上下剛度比結構的彈性分析對比以及對其進行的彈塑性分析結果對比,最后得出符合規(guī)范要求并且最符合實際要求的結構設計方案,對未來同類結構工程的設計具有非常深遠的借鑒意義。
[Abstract]:In recent years, the prosperous high-rise structure form is various, changes with each passing day, the high-rise assumes the high-speed development state. Among them, in the vast sea of all kinds of building forms, the high-rise building structure with transfer floor is a better one. The conversion layer not only meets the requirements of utility, but also completes the perfect transition of different upper and lower layers. Transfer layer is divided into the following types: beam transfer layer, plate transfer layer, box transfer layer, truss transfer layer and so on. Among them, the beam transfer layer is widely used in the world because of its clear transmission path, not complex force form and other excellent performance. However, the defects of traditional reinforced concrete beam transfer layer, such as excessive self-weight and difficult construction, make the new type of material beam transfer layer structure develop rapidly and be praised and favored. At present, it is very important and profound for the practical engineering application to study the seismic behavior of the beam-type transfer story system with new materials for high-rise building structures. In this paper, the steel reinforced concrete (SRC) is used as the beam transfer layer for numerical simulation of a high-rise building structure. The contents of the analysis are as follows: 1) the related design of the high-rise building structure with transfer story in the present design code and conceptual analysis is systematically discussed. And the seismic analysis method theory of high-rise building structure with transfer story and the development of steel reinforced concrete beam transfer story at home and abroad are analyzed. SAP2000 is used to model different frame shear wall structures caused by different transfer layer positions, and then fine response spectrum analysis and modal analysis are done for these different structural models. The modes and internal force distribution curves of each calculation scheme are analyzed. The seismic performance of each floor is compared with that of each floor, such as the displacement angle of each floor, the displacement of the top of the structure, and so on. The effect of this factor on seismic performance of this type of structure is discussed when it is in the elastic stage. 3) different values of the upper and lower stiffness ratios of different transfer floors are obtained. SAP2000 is used to establish different frame shear wall structures caused by different transfer floor stiffness, then modal analysis and response spectrum analysis are done for these different structural schemes, and the modes of each scheme are calculated. The displacement of the building vertex, the interstory displacement angle of each floor and the distribution curve of internal force are compared and analyzed to its seismic performance. By analyzing the effect of this factor on the seismic behavior of this type of building in the elastic stage (.4), the static elastic-plastic analysis of this type of building under the condition of frequent earthquake and rare earthquake is done by using the scheme model of Pushover for different values of the building, and through the performance point, The parameters such as loading steps, maximum interstory displacement angle and plastic hinge state are used to improve the response ability of the structure under earthquake. By comparing the elastic analysis and the elastoplastic analysis results of the structures with different transfer floor positions, the upper and lower stiffness ratios of the different transfer floors, the structure design scheme which meets the requirements of the code and is most suitable for the actual requirements is obtained. It is of great significance for the design of similar structure engineering in the future.
