EQUALS shaking table SERIES

The Earthquake and Large Structures Laboratory (EQUALS) is part of the Bristol Laboratories for Advanced Dynamics Engineering (BLADE) in the Faculty of Engineering at the University of Bristol, UK. It houses a 15t capacity, 6 DoF earthquake shaking table surrounded by a strong floor and adjacent strong walls up to 15m high. The shaking table consists of a stiff 3mx3m platform, weighing 3.8

The University of Bristol earthquake shaking table competition

The shaking table runs a series of greater magnitude shakes until only one tower remains intact. MEng in Civil Engineering students learn about the design of steel and concrete structures in the context of realistic multi-storey buildings incorporating common beam, column and slab arrangements.

Adaptive Control of Shaking Tables Using the Minimal

University of Bristol, Bristol BS8 1 TR, UK Traditional shaking-table testing has been limited by the effectiveness of conventional fixed-gain algorithms used in their control. These algorithms are normally based on linear models of the shaking table and specimen, whose parameters are assumed to be fixed for the duration of the test.

Earthquake laboratory University of Bristol

Shaking table / earthquake simulator (ES) platform The shaking table comprises a 3m by 3m platform supported by 8 hydraulic actuators. The table can carry up to 15 tonnes and (depending on the loading) can reach acceleration levels up to about 5g with peak displacements of ±150mm which makes it idea for testing specimens to destruction.

The development of shaking tables–A historical note

Jan 20, 2011· The earliest known shaking table, driven by hand‐power, was constructed in Japan at the end of the 19th century. At the beginning of the 20th century developments had moved to the Stanford University in the U.S. with the introduction of an electric motor to produce a more refined oscillatory motion in one direction, the response of the

Development of a high channel University of Bristol

Collecting data during shaking table tests is often challenging because the presence of the instrumentation and the associated cabling has the potential to affect the dynamic behaviour of the model. This issue has been encountered in some ongoing research at the University of Bristol investigating the seismic performance of Advanced Gas

Seismic Qualification Testing University of Bristol

An important practical application of the EPSRC shaking table is seismic qualification testing of electro-mechanical plant. This usually involves shaking the equipment with simulated earthquakes to prove its safe operation during and after a seismic event. Each test earthquake lasts about ten seconds and the sequence of shaking is carefully
