Progressive collapse performance analysis of precast reinforced concrete structures

Abstract: In this paper, the progressive collapse performance analysis of precast reinforced concrete (RC) structures is performed. A numerical simulation framework for precast RC structures is developed on the basis of the OpenSEES software, where the fiber frame element is used for beam and column type members and Joint2D element is used for the beam-to-column connections. The conjugated material models are then introduced, and a min-max failure criterion is imposed on the original models to reflect the steel fract… Show more

“…Thus, it is necessary to evaluate experimentally or numerically the behaviours and resistance of columns with non-conventional crosssection. Faced with this motivation, Feng et al (2019) [4] developed numerical simulations of the progressive collapse performance of precast reinforced concrete. Li et al (2017) [5] numerically evaluated segmental columns under blast loads.…”

“…The fiber section was characterized by the Concrete02 material model and Steel02 material model, which reflected the two uniaxial materials and described the united force‐deformation relationship of the section. The stirrup effects were considered in the confined concrete, and the compressive strength and corresponding strain of which were 1.3 times higher than those of the unconstrained concrete …”

“…The stirrup effects were considered in the confined concrete, and the compressive strength and corresponding strain of which were 1.3 times higher than those of the unconstrained concrete. 34 For the purpose of reflecting the precast-assembly features and presenting the joint mechanical states (e.g., shear deformations and interfacial properties), the Joint3D element 35 was adopted particularly to model the beam-column joint zone of the external SC-PBSPC BRBF substructure ( Figure 4A). The Joint3D element was defined in a three-dimensional domain with six external nodes and one central node.…”
