Abstract:
In reasonably modeling reinforced concrete structures with plane beam elements, the reinforcement and the concrete are regarded as different elements respectively, which would be joined together with the non-nodal connection method put forward under the principle of virtual work based on the displacement analysis at an arbitrary point in a plane beam element and according to the consistent condition of displacements. Then with that method, more problems of complex combination and connection can be conveniently and precisely simulated, such as reinforced members or members with changing sections in different construction phases. In the numeric crete beam and the strengthening effects on another reinforced concrete is verified and its convenience is demonstrated. examples, the displacement of a reinforced con- beam are analyzed, the feasibility of the method is verified and its convenience is demonstrated.
