中文摘要	型钢混凝土粘结滑移本构关系是型钢混凝土数值模拟分析的关键问题.进行型钢混凝土标准推出试件试验,对型钢混凝土粘结滑移性能和粘结滑移受力机理研究.根据荷载-加载端滑移曲线的试验研究结果,建立型钢混凝土特征粘结强度、特征滑移的统计回归计算公式,并提出型钢混凝土粘结滑移本构关系数学模型.进一步采用所建立粘结滑移基准本构模型对型钢混凝土推出试件进行 ANSYS 数值模拟分析,数值模拟结果与试验结果吻合较好.研究结果表明,所建立型钢混凝土粘结滑移本构模型简单实用,并且能较全面的反映混凝土强度等级、横向配箍率、型钢埋置长度和型钢保护层厚度等主要影响因素的影响.可为型钢混凝土粘结滑移性能和型钢混凝土结构数值模拟技术研究提供参考.; Bond-slip behavior on interface between shaped-steel and concrete is very important to mechani- cal performance and numerical simulation of SRC(steel reinforced concrete)structure,therefore a series of SRC push-out tests were conducted and presented.According to the experimental results of load-slip curves at load-end of all specimens,three key bond strengths and three key slippages were firstly defined,and the calculation formulas of these key bond strengths and slippage were founded by regressing method.Basic bond -slip constitutive relation models were established by mathematic method,and load-slip curves were calcu- lated based on the models,which were proved in good accordance with the experimental curves.Based on the ANSYS computer program,Sixteen SRC push-out test specimens experimented before were numerical simula- ted adopted the basic bond-slip constitutive relations models established above.Comparing with the numeri- cal simulation results and the experimental results,the basic bond-slip constitutive relation models were proved useful and could take into account the four main factors included concrete strength,area ratios of stir- rups,and embedment length as well as thickness of concrete cover of shaped-steel.It was concluded that the bond-slip constitutive relation models established here could be applied to further study on bond-slip behav- ior and numerical simulation of SRC structures.; 国家自然科学基金(资助号：50108013；50478120)．
