DIRECT DISPLACEMENT-BASED DESIGN FOR BUILDINGS WITH PASSIVE ENERGY DISSIPATION DEVICES

  • 摘要: 该文提出了一种计算位移型消能减震偏心结构能力谱的简化计算方法,通过结构变形分解,将偏心结构的能力谱曲线分解为平面Pushover能力谱及非偏心结构的纯扭转能力谱,并采用位移合成的方法得到最终的能力谱曲线。数值算例与有限元软件Sap2000分析结果进行对比,结果表明:该文提出的方法与有限元软件计算结果接近,是一种有效的简化计算方法。

     

    Abstract: A simple method for calculating pushover curves of asymmetric structure with displacement- dissipative devices is presented. The calculated progress of this method is carried out throughout decomposing the shaped structure to translation and torsion ones. The pushover curves of asymmetric structure with displacement-dissipative devices are formed by integrating the two curves. Numerical example result calculated by simple method was compared with that obtained by software Sap2000. The comparison shows that the simple method can provide an approving procession for engineering analysis.
