Abstract

Based on the second-order analysis of elastic element stiffness matrix considering connection's flexibility and second-order effect,a finite element method is used to study free vibration of semi-rigid steel frame.Through the comparison of examples' natural frequency,different factors influencing free vibration analysis are discussed.
- semi-rigidity,
- second-order effect,
- free vibration analysis,
- natural frequency
