城市区域建筑物震害预测剪切层模型及其参数确定方法

A MULTI-STORY CONCENTRATED-MASS SHEAR MODEL FOR URBAN REGIONAL SEISMIC DAMAGE PREDICTION AND ASSOCIATED PARAMETER DETERMINATION

  • 摘要: 传统基于易损性矩阵及单自由度模型的城市建筑震害预测方法已经不能满足现代城市震害预测精度和多样性的需要。多自由度剪切层模型由于具备可接受的精度和较高的效率,非常适合于城市区域建筑物的震害模拟。但其层间滞回模型的确定存在较大的困难。因此,该研究以国内外得到广泛应用的Hazus软件作为基础,提出了相应的城市区域建筑物震害预测剪切层模型,并基于Hazus软件中通过大量调查统计得到的建筑抗震性能参数,提出了剪切层模型参数的确定方法,为精细化的城市区域建筑震害预测提供参考。

     

    Abstract: Traditional methods in predicting urban regional seismic damage based on single-degree-of-freedom systems and response spectra analysis cannot meet the accuracy and various requirements of comprehensive disaster prevention for modern cities. The multi-story concentrated-mass shear (MCS) model is the most suitable model for urban regional seismic damage prediction due to its satisfactory level of accuracy and relatively high efficiency. However, determining inter-story hysteretic models and associated parameters can be difficult. In this study, an MCS model for urban regional seismic damage simulation based on the widely used Hazus program is developed. A method for determining associated parameters based on the built-in statistical data in Hazus is proposed. The outcomes of this study are expected to provide referencing information for refining urban regional seismic damage prediction.
