提出了钢筋混凝土超高层建筑的地震脆性评估分析的框架模型和应用案例。对于这类结构,由于没有任何随机的脆性关系存在,本文工作填补了区域地震影响评估的空白。所提出框架模型的关键是发展了典型的复杂超高层建筑系统的简单集中参数模型方法。在ZEUS-NL环境中所构建的这个模型能够有效进行高层结构的动力响应序列分析,并且能够精确计算复杂的行为和通过详细的模型分析所预测的交互作用,这在以前是不可能的。采用遗传算法选择这个模型的参数。对于双核墙和钢筋混凝土框架超高层结构,提出了改进的简单集中参数模型。模型中个别成分的精确性与详细的分析模型所预测的结果进行比较,提出了样本脆性曲线所提出的框架模型,对于带有框架和核或墙的超高层建筑结构脆性关系的开发是可行的。
The frame model and application cases of seismic fragility assessment and analysis of reinforced concrete high-rise buildings are put forward. For this kind of structure, the work in this paper fills in the blank of regional seismic impact assessment because there is no random brittle relationship. The key to the proposed framework model is the development of a simple centralized parameter modeling method for a typical complex super high-rise building system. This model, built in the ZEUS-NL environment, enables efficient dynamic response sequence analysis of high-rise structures and the ability to accurately calculate complex behaviors and analyze the predicted interactions through detailed models, which was previously impossible. Genetic algorithm to select the parameters of this model. For the dual-core wall and RC frame super high-rise structure, an improved simple centralized parameter model is proposed. The accuracy of the individual components in the model is compared with that predicted by the detailed analysis model, and the framework model proposed by the sample brittleness curve is proposed, which is feasible for the development of the brittle relationship between the structure and the nuclear or wall building .
