各国规范对于楼面峰值加速度规定的对比研究

COMPARATIVE STUDY OF RELEVANT SPECIFICATIONS ON PEAK FLOOR ACCELERATION IN CURRENT CODES OF DIFFERENT COUNTRIES

  • 摘要: 该文系统总结了各国抗震设计规范中对于结构楼面峰值加速度取值的相关规定。建立了一系列不同设计参数、不同振动周期的钢筋混凝土框架结构的有限元模型,对弹性和弹塑性结构进行了不同强度地震动作用输入下的时程分析。将楼面峰值加速度通过地面峰值加速度归一化,考察了结构各楼层楼面峰值加速度分布情况。结果表明,现行抗震设计规范中对楼面峰值加速度取值的相关规定不能很好地反映其在不同楼层的分布情况,有待进一步的研究。

     

    Abstract: Relevant specifications on the value of peak floor acceleration in current seismic design codes of different countries are systematically investigated in this paper. Finite element models of a range of reinforced concrete frame buildings with different design parameters as well as periods of vibration were established to study the floor acceleration response. The time history analyses were conducted on both linear and nonlinear structures subjected to input ground motions of varying intensities. The peak floor acceleration was normalized by peak ground acceleration and the distribution of peak floor acceleration in each story were analyzed. The results showed that the definitions of peak floor acceleration in current seismic design codes cannot accurately evaluate the distribution of different floors and further research is needed.
