| 摘 要： | 根据结构动力学理论证明了能力谱曲线的确定与侧向荷载分布模式间存在对应关系,指出对于不同的侧向荷载模式,应采用不同的能力谱曲线转化公式并给出了具体的表达式. 分别采用本文方法、传统方法和弹塑性时程分析对一个六层钢筋混凝土框架结构进行了计算,证明了本文方法计算精度更高. 利用该方法,采用多种侧向荷载模式对结构进行静力弹塑性分析,能将侧向位移反应可能范围限定得更小,使人们把握实际地震反应大小的准确性得以提高.

| Abstract: | Based on the structural dynamic theory,the relationship between capacity spectra and lateral load patterns was demonstrated.It was pointed out that different formulae of capacity spectrum curves should be used for different lateral load patterns and the formulas were given.A six-story reinforced concrete frame structure was designed and analyzed using the proposed method,the classical method and the time history analysis method respectively.The result shows that the proposed method is more accurate.Using th... |
