Internal Force Calculation Method of the Steel Portal Frames with End-Plate Bolted Connections

Article Preview

Abstract:

Simplified calculation of initial stiffness of end-plate bolted connections is given in the paper. Considering the influence of the end-plate bolted connections to the internal force of the steel portal frames, the modified elastic calculation of internal force is suggestted. Comparing with the finite element calculation results of different span steel portal frames, the calculated value is agree with the finite element calculation results. End-plate bolted connections are semi-rigid connections, and the flexibility of the connections affects the behavior of the frames, the internal force of rigid frames should be modified when semi-rigid connections used. The modified elastic calculation of internal force of the steel portal frames with end-plate bolted connections is simple and has good agree with the finite element results, which can give reference to engineering design.
