【摘要】：型鋼混凝土結(jié)構(gòu)是在混凝土中配置實(shí)腹式或空腹式型鋼,并配有箍筋和縱筋的結(jié)構(gòu),簡稱SRC結(jié)構(gòu),SRC結(jié)構(gòu)使得混凝土的抗壓性能和鋼材的抗拉性能都能得到很好的發(fā)揮,能有效的解決混凝土的抗拉性能不足問題,由于混凝土受壓能代替部分鋼材承受壓力,從而能夠節(jié)省鋼材達(dá)到良好的經(jīng)濟(jì)效益。由于型鋼混凝土結(jié)構(gòu)具有很多優(yōu)點(diǎn),優(yōu)于一般的混凝土結(jié)構(gòu)和鋼結(jié)構(gòu),近些年來越來越受到世界各國的重視。型鋼混凝土結(jié)構(gòu)越來越被廣泛地應(yīng)用于大跨結(jié)構(gòu)、高層建筑結(jié)構(gòu)和高聳結(jié)構(gòu)中,尤其是抗震區(qū)的建筑結(jié)構(gòu)中。本文首先對型鋼混凝土結(jié)構(gòu)的特點(diǎn)和在國內(nèi)外研究發(fā)展情況做簡要介紹,然后對型鋼混凝土柱軸壓比限值進(jìn)行研究,分析了鋼筋混凝土柱與型鋼混凝土柱軸壓比之間的關(guān)系,以大、小偏心界限破壞平衡條件為基礎(chǔ),推導(dǎo)型鋼混凝土柱的軸壓比限值公式。對型鋼混凝土柱正截面和斜截面承載力進(jìn)行研究,并對國內(nèi)外相關(guān)規(guī)范的計(jì)算方法對比和總結(jié)。其次,對偏心受壓型鋼混凝土柱的二階效應(yīng)進(jìn)行分析,研究其對SRC柱承載力的影響,并對SRC柱的偏心距增大系數(shù)進(jìn)行理論分析,總結(jié)國內(nèi)外相關(guān)學(xué)者在這一方面的研究成果。并運(yùn)用有限元分析軟件ANSYS對兩組不同軸壓比和不同配箍率的型鋼混凝土柱在低周反復(fù)荷載作用下進(jìn)行有限元分析。最后通過數(shù)值模擬的結(jié)果得到在不同軸壓比和不同配箍率情況下,型鋼混凝土柱的滯回曲線和骨架曲線,從而分析軸壓比和配箍率對型鋼混凝土柱受力性能的影響。
[Abstract]:Steel reinforced concrete (SRC) structure is a kind of solid or hollow type steel structure in concrete, which is equipped with stirrups and longitudinal bars. It is called SRC structure, which makes the compressive performance of concrete and the tensile performance of steel can be well played. It can effectively solve the problem of insufficient tensile performance of concrete. Because concrete can replace some steel under pressure, it can save steel to achieve good economic benefits. Because steel reinforced concrete structure has many advantages, it is better than common concrete structure and steel structure, so it has been paid more and more attention in the world in recent years. Steel reinforced concrete (SRC) structures are more and more widely used in long-span structures, high-rise building structures and high-rise structures, especially in seismic areas. In this paper, the characteristics of steel reinforced concrete structure and its research and development at home and abroad are briefly introduced, then the limit value of axial compression ratio of steel reinforced concrete column is studied, and the relationship between reinforced concrete column and steel reinforced concrete column axial compression ratio is analyzed. Based on the failure equilibrium condition of large and small eccentricity limits, the limit formula of axial compression ratio of steel reinforced concrete columns is derived. The bearing capacity of normal section and inclined section of steel reinforced concrete column is studied, and the calculation methods of relevant codes at home and abroad are compared and summarized. Secondly, the second order effect of eccentrically compressed steel reinforced concrete columns is analyzed, and the influence on the bearing capacity of SRC columns is studied. The increasing coefficient of eccentricity of SRC columns is theoretically analyzed, and the research results of domestic and foreign scholars in this field are summarized. Two groups of SRC columns with different axial compression ratio and different hoop ratio were analyzed by finite element analysis software ANSYS under low cyclic cyclic loading. Finally, the hysteretic curves and skeleton curves of SRC columns are obtained under different axial compression ratios and different hoop ratios, and the effects of axial compression ratio and hoop ratio on the mechanical properties of SRC columns are analyzed.
