| 摘 要： | 在型钢混凝土柱基础上提出预压型钢混凝土柱,并对预压型钢混凝土柱研究意义进行了概要分析。采用ANSYS有限元分析软件,通过对9个不同混凝土强度等级、不同型钢预压比、不同轴压比的预压型钢混凝土柱的低周反复荷载试验,得到预压型钢混凝土柱在不同轴压比、型钢预压比下的破坏形态和滞回曲线。研究结果表明:预压型钢混凝土柱有良好的抗震性能,但是其随着轴压比增大和混凝土强度的提高而降低。 |
| 关 键 词： | 预压型钢混凝土柱 型钢预压比 轴压比 滞回特性 |

| Abstract: | Base on steel reinforced concrete columns,a new column form named steel reinforced concrete columns of prec ompressed stress was presented.The engineering significance and recent researches of the steel reinforced concrete columns of precompressed stress were introduced.The article applies the ANSYS finite element analysis software,through to the low week repeatedly load experiment of 9 steel reinforced concrete columns of precompressed stress for different concrete intensity rank,different steel precompressed stress ratio and different axis presses ratio low week repeatedly load experiment,obtains 9 steel reinforced concrete columns of precompressed stress destruction shape and stagnates curve.1t was concluded that the steel reinforced concrete column could improve the earthquake resistance performance,but it will be reduced when improved the concrete intensity and the part axis press ratio. |
| Keywords: | steel reinforced concrete columns of precompressed stress steel precompressed stress ratio axial compress ratio hysteretic characteristic |
