To simulate a quake in the classroom, you need to create a simple testing device called a "shake table." Your educator guide and engineering journal give detailed instructions for making one, using . . . self-adhesive , two notebook-sized core boards, 2 clear plastic tubes, hex nuts, and; common office supplies like tape and rubber bands.

Sep 01, 2021· The shake table testing shows that the maximum difference in the natural frequencies of the crane for the portal sway mode, between the friction boundary and pin support, was 2.1%. Due to the effects of derailment and uplift of the landside legs, the bending moments in the crane's seaside legs with a friction boundary were 109% higher …

This teacher's manual contains a sample set of data for the experiments in the Student Manual. The ultimate goal for these experiments is to compare results from an earthquake simulation done on the UCIST Shake Table to analytical results using SAP 2000 software. 1.1 Introduction The UCIST Shake Table was designed for experimental use and for

Shake tables. The Center has three biaxial shake tables in operation. Manufactured by MTS, each table measures 14 x 14.6 ft (4.3 x 4.5 m), has a stroke of ±12 in (± 300 mm), and can reach a peak velocity of 40 in/sec (1000 mm/sec) and an acceleration of 1g with a 50 ton payload (445 kN). All three tables can be constrained to act together as a single …

The UW's shake table was installed in the early-1990's. Since then, hydraulic control technology has advanced significantly. While the shake table has the structure or "bones" to test structures with a plan area as large as 12 feet by 15 feet and weights up to 30,000 lbs, the controller and oil accumulation system limit the capabilities ...
