Paper Title:
Research on Additional Internal Force and Deformation of the Portal Frame Construction Caused by Surface Deformation
  Abstract

This article focuses on the construction of portal frame without crane. The dynamic variational laws of the additional internal force and displacement of the portal frame construction under the elongation, compression, tilt (uneven settlement), positive curvature and negative curvature deformation of ground are calculated by numerical simulation method, using the structural finite element analysis software – ANSYS. We find that the swing column will alter the distribution of the frame construction additional internal force with the surface deformation; and it can effectively restrict additional deformation of the beam, which is caused by the surface deformation. The swing column increased the ability of resist surface deformation of frame construction with compression and uneven settlement deformation; but it reduced the ability of resist surface deformation of frame construction with elongation deformation. Moreover it indicates that the reciprocity between base and foundation will alter the distribution of the frame construction additional internal force with the surface deformation.
