槽钢混凝土柱(CSRC)作为一种新型的结构形式，由于它的受力性能、延性以及抗震性能较好，在工程应用方面有广阔的前景。但目前槽钢混凝土柱(CSRC)受力性能的研究还较少，理论研究滞后于工程实践，因此对其受力性能研究具有重要的理论意义和工程应用价值。 本文利用有限元分析软件ANSYS模拟槽钢混凝土柱(CSRC)在实际地震作用下的破坏过程，并考虑了剪跨比、轴压比、槽钢放置方式、缀条角度以及缀条间距等五种影响因素对CSRC试件受力性能以及抗震性能的影响。本文建立了12个有限元模型，深入分析试件在单调水平荷载作用下的承载力与延性系数以及在循环荷载作用下的滞回性能、骨架曲线、刚度退化曲线以及应力云图中应力分布情况。 研究结果表明：在单调水平荷载以及循环荷载作用下，CSRC试件受力性能与抗震性能良好，滞回曲线饱和丰满，稳定性较好，且没有明显的捏缩现象，这表现出较好耗能性能。在五种影响因素中，剪跨比与轴压比因素对CSRC抗震性能影响显著，设计时剪跨比与轴压比值不宜过高或过低，剪跨比一般选用1.5左右，轴压比宜取值在0.4—0.6，一、二、三级抗震等级分别不宜超过0.7、0.8、0.9。槽钢放置方式对CSRC试件的抗震性能也有一定影响，在循环荷载作用下翼缘向外的试件应力集中明显，耗能系数较小，不利于工程中应用。缀条因素对CSRC试件抗震性能影响较小，缀条起到连接两个槽钢以及传递应力作用，防止槽钢因局部受力不均发生整体失稳破坏，缀条本身承受应力较小。最后结合有限元计算结果与SRC规范，根据线性回归，本文提出CSRC斜截面承载力修正计算方法，修正后计算值接近试验值，仅供实际应用参考。 本文深入分析CSRC在单调水平荷载以及循环荷载作用下的受力性能以及抗震性能，为进一步分析研究打下良好的基础。

The channel steel reinforced concrete column is a new form of structure, Because of its stress performance, ductility and performance, it has a broad prospect in engineering application. However at present the channel steel reinforced concrete column stress performance study is less, theoretical research lags behind engineering practice, so research on its mechanical performance has important theoretical significance and engineering application value. This text simulate lattice type steel reinforced concrete column in the actual failure process under the action of earthquake which use the finite element analysis software ANSYS. And it consider the effect of five factors which including the shear span ratio, the axial compression ratio, the channel form, lacing angle and spacing influence the force performance and seismic performance of the CSRC. A total of 13 finite element models were established, and studied the ductility，bearing capacity and studied hysteresis curves, skeleton curves, stiffness degradation curves of the member and stress distribution diagram under cyclic load. Research results show: CSRC specimens have the good mechanical properties and seismic performance, hysteresis curve of saturated fullness, good stability and no obvious pinch phenomenon under the monotonic loading and cyclic loading ,it shows good energy dissipation. In the five factors, the shear span ratio and axial compression ratio should not be too high or too low, the shear span ratio is generally used in about 1.5, the axial compression ratio control between 0.4 and 0.6.The test also deduced CSRC of axial compression ratio limit according to the specification, only for reference. The steel factors also have a certain impact on the seismic behavior of the CSRC, under the cyclic loading changing angle of channel steel specimen shows stress concentration obviously and very small energy dissipation coefficient and it is prone to failure, not suitable for engineering use. The factor of lacing bar has the less effect on the seismic behavior of the CSRC, it could connect the two channel and transfer stress, prevent from the uneven force due to local channel overall instability destruction, itself is not subjected to stress. Finite according to linear regression, this paper puts forward the calculation formula of ultimate bearing capacity of inclined section of CSRC, which result and experiment result error is small, providing reference for its application in practical engineering. This paper analyzes in depth the CRSC under monotone horizontal load and cycle load, laying a good foundation for further study.
