钢筋混凝土剪力墙非线性单元模型的研究
|
摘要
本文首先对等效框架模型、多竖直杆单元模型作了改进。然后应用改进等效框架模型、改进多竖直杆单元模型及分层壳单元模型,对不同轴压比的三片剪力墙构件模型与一个14层筒中筒结构模型进行了计算分析,并与实验结果作了比较。结果表明:改进多竖直杆单元模型在所有情况下均可取得较好结果,是适用性较强的剪力墙非线性单元模型;多层壳单元模型在轴压比较大时可取得很好的结果,当轴压比较小时,应用多层壳单元模型应慎重;改进等效框架模型只在轴压比适中时可取得较好结果,其他情况下可能会引起较大的计算误差。
In this paper,analogous frame model(AFM) and multiple vertical line element model(MVLEM) have been improved.The improved AFM,MVLEM and multi-layer shell element model(MLSEM) have been applied to the inelastic static and dynamic response analysis of structural walls.Three isolated cantilever walls with different axial compressive ratios and a 14-story RC tube-in-tube structure are selected as illustrative examples.A comparison between analytical and experimental results indicates that the improved AFM is suitable for the inelastic response calculation of structural walls with medium axial compressive ratio,the MLSEM is proved to be most suitable for the prediction of inelastic behavior of structural walls with higher axial compressive ratios,and the improved MVLEM is suitable for the inelastic behavior and response calculation of structural walls.
