摘要
Abstract
This paper presents an experimental study on elliptical hollow sections under combined compression and cyclic bending.A total of four specimens are tested,where the main parameters are cyclic loading directions and load ratio.The main focus of the study is on their failure mode,hysteresis response,skeleton curves,and ductility supply.The test results show that:local buckling,featured by outward bulges of the tube wall,is the governing failure mode of the specimens.Increasing the load ratio tends to compromise both the lateral load carrying capacity and ductility of the specimens.In addition,strong axis cyclic bending leads to higher lateral load carrying capacity but reduced ductility compared with the case of weak axis bending.关键词
