椭圆钢管柱受压性能研究进展

摘要

为了促进中国椭圆钢管结构的研究与应用,通过对国外椭圆钢管的应用和研究相关文献的调研与分析,归纳总结了椭圆钢管柱的截面特性、截面分类以及在轴压和压弯荷载作用下的结构性能等问题,发现目前国外对于椭圆钢管的研究主要关注单个构件的受力性能,对于椭圆钢管结构节点性能及椭圆钢管混凝土柱性能的研究将是未来研究的重点.%In order to promote the research and application of elliptical hollow section (EHS) in China,through investigation on literature about application and research of EHS,the structural behaviors of EHS columns were summarized about cross section characteristic and classification,and structural behaviors under axial compression as well as under combined compression and bending load.The recent research work of EHS is mainly about bearing capacity of individual component,and the future research shall focus on properties of the joints of EHS structures and concrete-filled EHS columns.
