Shake table testing and finite element modeling of a modular
The shake table tests were performed at the Laboratory for Earthquake Engineering (LEE) of the National Technical University of Athens (NTUA). The shake table comprises a 4 × 4 m, 6-degrees-of-freedon platform. The displacement and velocity capacity of the shake table is ±100 mm and 1000 mm/s, respectively.
