Seismic resistance of composite structures SRCS
Project ID: 7210-SA/506Funded under: ECSC-STEELRES 7C
The first period of this research was devoted to the realisation of nearly quasi-static cyclic 50 tests on full sized composite specimens which were divided into four series: (i) tests on T-shaped exterior column/beam joints; (ii) tests on cross-shaped interior column/beam joints; (iii) tests on complete frames; (iv) partial tests on different elements. During the second period, a numerical code was developed to simulate concrete structures under seismic action, taking into account geometrical non-linearities as well as the elasto-plastic behaviour of steel and the deterioration of concrete. The present research showed the benefits from using composite structures in earthquake prone zones, as concrete increases the resistance by about 50 % in the elastic field, and also increases the stiffness. Other advantages are that concrete largely prevents local buckling, and contributes to the shear panel behaviour. Finally, after complete concrete crushing the structure behaves like a bare steel structure when submitted to very large displacements.
