| 中文摘要 | 在型钢混凝土结构基础上提出核心型钢混凝土结构,并对核心型钢混凝土结构研究意义进行概要分析。采用CSI公司通用程序Section Builder-8对56个核心型钢混凝土柱试件进行截面受力性能全过程非线性分析,得到各试件的弯矩-轴力相关曲线(M-N曲线)、弯矩-曲率曲线(M-Φ曲线)及弯矩-轴力-曲率曲线(M-N-Φ曲线)。结合核心型钢混凝土柱截面全过程非线性分析结果,对核心型钢柱截面曲率延性系数进行分析,并着重考察核心混凝土柱中核心型钢的截面高度、配钢率、型钢截面形式及柱轴压比等主要参数对柱受力性能的影响。研究结果表明,核心型钢能有效改善核心型钢混凝土延性,核心型钢混凝土柱轴压比限值相对钢筋混凝土柱可以明显提高。; Based on steel reinforced concrete(SRC) structures,a new structures form named core steel reinforced concrete(CSRC structures) was presented.The CSRC structures were formed by embed small size steel shape such as H shaped-steel,T shaped-steel and steel tube into the section centre of reinforced concrete membranes.The engineering significance and recent researches of the CSRC structures were introduced.Using the CSI Section builder-8 computer program,full-process section nonlinear analysis on mechanical behaviour of 56 CSRC column specimens were conducted.Moment-axial force interaction curves(M-N curves),and moment-curvature curve(M-Φ curves) as well as force-moment-curvature curves(M-NΦ curves) were obtained.The section ductility ratios of the CSRC columns were calculated according to the analysis results.The influence of four main factors including height of shaped-steel,volume ratio of shaped-steel,and steel style as well as the axial compression ratio on the mechanical behaviour of the CSRC column were fully studied.It was concluded that the core small size shaped-steel could improve the section ductility,and the limitation values of axial compression ratio of CSRC column could be enlarged relative to the reinforced concrete columns.; 国家自然科学基金资助项目(50478120); 福建省青年科技人才创新项目(2005J032) |
