Research on Load Distribution Effect of Load Distributed Structure in the Complex Rotational and Translational Engineering

Article Preview

Abstract:

In view of the large axial force column underpinning of the complex rotational transportation engineering,a new underpinning structure which with six diagonal bracings was proposed in this paper. Using SAP2000 software built four different calculating models with different support forms, and analyzed internal forces of members of the underpinning structure, discussed the load distribution effects on change of parameters including the inclined angle α between the inclined support and column, the angle θ between the inclined support horizontal projection and axis, inclined support section sizes, coupling beam section size and whether there are the horizontal forces. The results show that the load distribution effects of whole model and of single column model have little difference, but the single column model underestimates the axial forces of the inclined supports. α and θ have a great influence on load distribution effect, and smaller α is better. The load distributed result can be very good to meet the requirement of rotating shift engineering.
