鋼-混凝土混合結(jié)構(gòu)地震反應(yīng)分析的CCQC和FDCQC方法及其應(yīng)用

［摘要］鋼-混凝土混合結(jié)構(gòu)是典型的非比例阻尼結(jié)構(gòu)系統(tǒng)。通過將Rayleigh阻尼理論應(yīng)用于各個(gè)結(jié)構(gòu)單元，建議了一種適合于混合結(jié)構(gòu)計(jì)算的非比例阻尼系統(tǒng)模型，并以此為基礎(chǔ)在PMSAP軟件中實(shí)現(xiàn)了用于非比例阻尼結(jié)構(gòu)地震反應(yīng)分析的CCQC方法和強(qiáng)迫解耦CQC方法(FDCQC)。通過對若干典型算例的地震反應(yīng)分析計(jì)算，檢驗(yàn)了FDCQC方法在鋼-混凝土混合結(jié)構(gòu)地震反應(yīng)分析中的精度。結(jié)果表明，該非比例阻尼系統(tǒng)模型比較合理。FDCQC方法在鋼-混凝土混合結(jié)構(gòu)地震反應(yīng)分析中的計(jì)算結(jié)果與比較精細(xì)的CCQC方法結(jié)果相當(dāng)接近，誤差一般不超過5%，可以滿足工程要求。

CCQC and forced decoupling CQC method for earthquake responseanalysis of hybrid structure composed of steel and concrete

Huang Jifeng, Zhou Xiyuan(China Academy of Building Research, Beijing 100013, China)

Abstract:Applying the Rayleigh damping theory onto individual members of the structure, it proposes a kind of damping model to handle the global non-proportional damping peculiarity of hybrid structure composed of steel and concrete. Based on the proposed damping model, the CCQC (Complex Complete Quadratic Combination) method and FDCQC (the forced decoupling CQC) method, which are two approaches that can be adopted in the earthquake response analysis of non-proportionally damped structure, are implemented in the PMSAP. Then, through computation and comparison for several typical example structures, the accuracy of FDCQC method in the earthquake response analysis of steel-concrete hybrid structure is verified. The results show that the non-proportional damping model proposed is reasonable and the computational results from the FDCQC method are very close to those from the CCQC method, a more delicate algorithm, and the relative error of FDCQC method is generally less than 5 percents compared to CCQC method. Hence, FDCQC method can be used as an effective tool in the earthquake response analysis of hybrid structure composed of steel and concrete.

Keywords:steel-concrete hybrid structure; non-proportionally damped structure; CCQC method; forced decoupling CQC method; earthquake response
