Finite Element Simulation of Reinforce-concrete Frame Beam to Resist Progressive Collapse
Abstract
The finite element model for reinforced-concrete frame beam to resist progressive collapse was established by ADINA program, which geometrical and material non-linearity considered. Axial forces are often present in reinforced- concrete beam at the ultimate load as a result of the boundary conditions and geometry of deformation of the beam segments. So the ultimate load-carrying capacity of reinforced-concrete frame beam was increased because of the arching and cable action (compressive and tensile membrane action). The influence of the beam to resist progressive collapse has been discussed such as steel ratio, span-depth ratio. It shows that the finite element model presented is feasible and can be applied to further research on engineering practice for reinforced-concrete frame structure to resist progressive collapse.
