【摘要】 依据压弯构件分析的基本原理,通过编制Matlab程序和算例对钢筋混凝土压弯构件在载荷作用下的变形性能进行了分析,考虑了箍筋约束作用和塑性铰的影响,得到了此类压弯构件的M-Φ曲线、P-Δ曲线,并对此进行了理论分析,提出了压弯构件变形性能的变化规律,为该类型构件的设计和应用提供了参考。更多还原

【Abstract】 Based on the basic principle of compression-flexure member,deformation behavior of R.C.compression-flexure members under load was analyzed with Matlab.The effects of confined concrete and plastic hinge were taken into consideration.The moment-curvature curve,load-deflection curve of this type of compression-flexure member were gotten and analyzed.Accordingly,the deformation behavior change law of R.C.compression-flexure member is described,which is helpful to the design and application of the member.更多还原
