Abstract:
Through the finite element simulation to study the local stability of the circle-castellated beams, reasonable finite element model was established using finite element software and in-depth analysis of the local stability of the circle-castellated beams on the basis of the castellated beams shear performance test. The same span of the circle-castellated beams, deformation stability performance under two point loads simulation, got deformation form of castellated beams under different pitch of holes, opening ratio, stiffener thickness, depth-thickness ratio. The local stability properties of the same span of the circle-castellated beams are directly related to opening ratio and web depth-thickness ratio changes, which has little effect with the change of hole spacing, stiffener thickness. Using the appropriate opening ratio, web depth-thickness ratio plays an important role on improving the local stability of web under the shear force and the bending moment.
