摘要: When a shallow arch is subjected to an in-plane load that applied suddenly, the will oscillate about equilibrium position due kinetic energy imparted by sudden load. If suddenly sufficient large, motion of may reach unstable position, leading dynamic buckling arch. This paper presents study pin-ended circular under central radial with infinite duration. The method conservation used establish criterion for and analytical solutions lower upper loads this duration are obtained. It found than its static loads, increases increase dimensionless geometric parameter introduced. effect preloading on also investigated. pre-applied decreases but sum
