A 1-g shaking table investigation on response of a

Nov 15, 2018 As summarized in Table 2, 1-g shaking table scaling laws recommended by Iai [20, 56] were adopted to design and manufacture the reduced-scale physical model. Considering the similitude requirements for modeling the prototype, specifications of the shaking table and the laminar box, a scaling factor of \( n = 8.5 \) was chosen for the

Shaking table tests on the seismic performance of a

Jul 14, 2017 Shaking table and soil box. The tests were conducted on a unidirectional shaking table with a dimension of 4.86 m (in excitation direction) 3.36 m. The laminar soil box used in this study is independently-developed by the Nanjing Tech University as shown in Fig. 2. The internal net size of the box is 3.5 m in length, 2.0 m in width and 1.7 m
