| Abstract: | Finite element analysis software ANSYS is used to perform numerical analysis.Multistory frames with semi-rigid connections of different initial stiffness are constructed together with corresponding rigid frame.The influence of connection stiffness to natural frequencies of structures is analyzed.Further by adopting time–dependent method structures under excitation of seismic waves are analyzed.The influence of connection stiffness to the time cures of top point lateral displacement and column base shearing force of frames are studied. |
