The material and structural thermal deformation characteristics of a steel stiffened panel under various fire-extinguishing methods were investigated experimentally. Propane gas was used to generate jet fires for panels widely as offshore installation structures. the initial imperfection (initial deflection residual stress) occurring during fabrication measured analyzed before after fire experi...

Free vibration behavior of laminated composite plates stiffened by different lattice structures is considered. To simulate free vibration, finite element models were created with Ansys Parametric Design Language (APDL). In the models, SHELL181 and BEAM181 elements used to model structures, respectively. The influence stiffeners on natural frequencies plate examined for clamped-free-clamped-free...
