Effect of axial compression ratio to ductility of T-shaped components

KONG Xiangya1,SHEN Dongjian1,KONG Xiangsong2(1.Hebei Institute of Architectural Desigh & Research Co.,LTD.,Baoding 071001,China;2.China University of Mining and Technology,Beijing 100083,China)  
By numerical integration method for the preparation of the T-shaped components ductility nonlinear analysis process,through reinforcement of the two sections of the form,such as T-shaped components in different axial compression ratio under the M—φ curve was calculated,analysis,obtained that the impact of axial compression ratio to the T-shaped yield curvature is smaller than the ultimate curvature,to the T-shaped components,the ductility is bad when load angle of 90 ° and 180 °,increase acromegaly longitudinal reinforcement or the provision of edge components,the component's section can be improved ductility.
