【摘要】：为分析施工误差对RC框架结构可靠性的影响,对某钢筋混凝土框架结构工程进行现场测量,获得了梁柱截面尺寸、保护层厚度、箍筋间距和混凝土抗压强度等施工误差的统计分布规律.基于工程结构可靠度的基本理论和承载能力极限状态方程,采用验算点法计算了实际工程中典型的框架梁和框架柱的可靠指标,并详细分析了各施工误差对构件可靠指标和结构可靠性分级的影响,以及影响钢筋混凝土结构框架结构可靠度的参数敏感性.分析结果表明,施工误差对结构构件的可靠性存在不可忽视的影响.本文研究结果有助于工程设计、施工和监管过程中把握施工误差中需严格控制的重点参数和偏差范围.
[Abstract]:In order to analyze the influence of construction error on the reliability of RC frame structure, the field measurement of a reinforced concrete frame structure project is carried out, and the section size and protective layer thickness of Liang Zhu are obtained. Statistical distribution of construction errors such as hoop spacing and concrete compressive strength. Based on the basic theory of engineering structure reliability and the limit state equation of bearing capacity, the reliability indexes of typical frame beams and frame columns in practical engineering are calculated by using the checking point method. The influence of each construction error on the reliability index and structural reliability classification of reinforced concrete structure, as well as the parameter sensitivity affecting the reliability of reinforced concrete structure frame structure are analyzed in detail. The analysis results show that the construction error has an important influence on the reliability of structural members. The research results of this paper are helpful to grasp the key parameters and deviation ranges that need to be strictly controlled in the process of engineering design, construction and supervision.
