DYNAMIC RESPONSE AND PARAMETER ANALYSIS OF HIGH-STRENGTH CIRCULAR STEEL TUBE UNDER LATERAL IMPACT
This paper presents a numerical analysis of the dynamic response of high-strength circular steel tubes subjected to lateral impact loads.By examining both the global and local deformations of the steel tubes,as well as the resultant impact forces,the dynamic response characteristics of the tubes under varying diameter-to-thickness ratios,impact locations,and impact heights are investigated to elucidate the influence of these parameters on the dy-namic behavior of the steel tubes.The findings indicate that impact height and diameter-to-thickness ratio are sig-nificant factors affecting the peak impact force and mid-span deformation of the tubes.Specifically,an increase in impact height results in higher peak impact forces and greater mid-span deformations,whereas a higher diame-ter-to-thickness ratio leads to lower peak impact forces but increased mid-span deformations.
