Experimental and numerical dynamic analysis of beams subject to non-uniform seismic support excitation
The subject of the present study is dynamic response of beam bridges under spatially variable ground movement (the so-called multi-support excitation). The phenomenon of spatial variability of ground motion mostly affects larger structures with greater distance between supports, such as long bridges, dams, tunnels etc., playing an important role in their safety and durability. Such effects may result in structural failure due to excessive relative displacements between the supports. The study includes formulation of the free and forced vibration equations along with solution procedures applied to simply-supported and cantilever beam systems. The modal analysis will be used as the method to calculate the dynamic response (displacements, velocities and accelerations of the nodal points as well as the internal forces) of such systems to support excitation. Since the Faculty of Civil Engineering in Rijeka possesses two shake tables, all the obtained results will be compared with those provided experimentally. For the experimental part, the 3D non-contact optical displacement and deformation measurement system will be used for data management and post-processing. Computational analysis of structures, especially large ones, subject to spatial variability of ground motion in seismic areas is still relatively unexplored and further research supported by controlled laboratory testing is highly recommended for future construction planning and structural design.
