Experimental study and numerical simulation of plane steel frame with rubberized connecting technology subjected to seismic effect

Abstract EN

This paper represents experimental and numerical study the behavior of the rubberized steel frame connections.

One single-bay, one-story without elastic buckling are cyclically tested.

The experimental specimens are simulated and analyzed by the ABAQUS program.

Four specimens of steel plane portal frame are investigated under horizontal reversed cyclic loads.

The specimen connections are developed by using different diameters of composite steel bolts/rubber instead of conventional steel bolts to connect the beams with columns.

The yield and ultimate strength, ductility, envelope curves, and damping ratio of these specimens are analyzed and compared.

The finite element method is used to establish and verify the results of the laboratory test.

The results of the experimental and numerical tests gave a large load-carrying capacity, reduction in the stresses, excellent ductility and energy dissipation capacity, and remarkably improved damping ratio.
