摘要
介绍了稳健设计法的基本内容、一般步骤及其在梁柱外节点抗剪强度分析中的应用,引入信噪比,用软化桁架模型分析地震作用下钢筋混凝土梁柱外节点抗剪强度,并用稳健设计对影响钢筋混凝土梁柱外节点抗剪强度的因素进行分析,得出了各种影响因素的重要程度,其中竖向箍筋强度对外节点抗剪强度影响最为明显,混凝土标准抗压强度和水平箍筋屈服强度次之。为以后设计和施工提供了理论依据。
The basic contents and general steps of robust design and its application in the analysis of shear strength of exterior joints of beam column are introduced. The softened truss model is applied to predict shear strength of exterior RC beam-column joints for seismic resistance. And robust design is applied to analyze several important factors of shear strength of exterior RC beam-column joints. The results give the important degree of different factors and the yield strength vertical reinforce is the most important factor to affect the shear strength of component, next to the concrete compression strength. It is could be used in future design and construction.
