Abstract: To study seismic behavior of new Tianjin library, a shaking table test of a 1/20 scale model is carried out for the main structure of the library. A steel frame-bracing system is employed in the main structure of the library. There are lots of removing columns and trusses with cantilevers in the interior structure with an irregular fa鏰de. Accordingly, this paper designs and products thoroughly the test model, including the selection of model material, the similitude-scaling relationship, the discussion for the model construction technology and design of test program. Finally, this paper lists the main result for the shaking table test.
