| Abstract: | The stiffness of semi-rigid beam-column connections are simulated with rotational spring.Typical portal frame structure is selected as the finite element model.In ANSYS parameter design language,program of semi-rigid portal frame with different rotational stiffness for resisting wind load by Monte-Carlo stochastic finite method based on Latin Hypercube Sample method is obtained.Relation between structural reliability index and different rotational stiffness is obtained.Design suggestions were put forward on... |
