【摘要】：鋼筋混凝土框架結(jié)構(gòu)是一種很常見的結(jié)構(gòu)形式,由于其設(shè)計理論成熟,能夠根據(jù)實際需要對建筑空間進行靈活布置,利于安排較大空間等優(yōu)點,在我國的實際工程中得到廣泛應(yīng)用。為了研究現(xiàn)澆樓板對鋼筋混凝土框架結(jié)構(gòu)抗震性能的影響,本文參考了大量國內(nèi)外學(xué)者的相關(guān)成果,總結(jié)并分析各種有效翼緣寬度的建議取值,最終選取一種有效翼緣寬度設(shè)計出六組不同的空間框架模型,運用SAP2000程序分別進行靜力彈塑性方法分析,研究塑性鉸出現(xiàn)規(guī)律,結(jié)構(gòu)破壞機制。依據(jù)我國現(xiàn)行《建筑抗震設(shè)計規(guī)范》(GB50011-2010)中有關(guān)保證鋼筋混凝土框架結(jié)構(gòu)實現(xiàn)“強柱弱梁”的規(guī)定,本文針對不同抗震等級的二、三級鋼筋混凝土框架模型,考慮不同大小柱端彎矩增大系數(shù),研究其對框架抗震性能的影響,并提出對實際設(shè)計可行的建議。影響鋼筋混凝土框架結(jié)構(gòu)抗震性能的因素有很多,本文在前人的基礎(chǔ)上,從樓板對梁端負(fù)彎矩影響的角度去研究結(jié)構(gòu)的抗震性能,得出一些有益的結(jié)論,為今后規(guī)范的修訂以及相關(guān)工程應(yīng)用提供相應(yīng)的參考。
[Abstract]:Reinforced concrete frame structure is a very common structural form. Because of its mature design theory, it can arrange the building space flexibly according to the actual needs, which is beneficial to the arrangement of large space. It is widely used in practical projects in our country. In order to study the effect of cast-in-place floor slab on seismic behavior of reinforced concrete frame structure, this paper summarizes and analyzes the suggested values of effective flange width by referring to the related achievements of a large number of scholars at home and abroad. Finally, six groups of different spatial frame models are designed by choosing an effective flange width. The static elastic-plastic method is used to analyze the plastic hinge and the failure mechanism of the structure is studied by using SAP2000 program. According to the provisions of the current Code for Seismic Design of buildings (GB50011-2010) in China, which guarantee the realization of "strong column and weak beam" in reinforced concrete frame structures, this paper aims at the second and third grade reinforced concrete frame models with different earthquake resistance grades. Considering the increasing coefficient of bending moment at the end of columns of different sizes, the influence of the coefficient on the seismic behavior of the frame is studied, and some feasible suggestions for practical design are put forward. There are many factors that influence the seismic behavior of reinforced concrete frame structure. Based on the previous research, this paper studies the seismic behavior of reinforced concrete frame structure from the angle of the negative moment of floor slab on the beam end, and draws some useful conclusions. For the future revision of the code and related engineering applications to provide the corresponding reference.
