A simplified two degrees of freedom (2-DOF) lumped masses model accounting for nonlinear contact interaction and material nonlinearities is used to describe the dynamics of the phenomenon.
Along these lines, a comprehensive distributed-parameters nonlinear model that includes both geometric and material nonlinearities is developed.
To this end, this paper presents the nonlinear fire analysis, in which the geometric and material nonlinearities are with recourse to the higher-order element stiffness formulation and the refined plastic hinge approach, respectively.
The reasons for the research level on stability of RC-structures connected with material nonlinearities are the seldomness of large but thin concrete shells and the complex nonlinear behavior of reinforced concrete.
Both geometric and material nonlinearities are considered.
Geometrical and material nonlinearities were considered in the model.
Both geometric and temperature-dependent material nonlinearities are accounted for.
Large displacements and material nonlinearities are taken into account.
Both geometric and material nonlinearities are included in the proposed analysis.
The initial geometric imperfection and material nonlinearities were carefully considered in the analysis.
