The paper discusses the use of rubber bearings in base isolated structures. In Japan alone there are likely to be 100 base-isolated buildings completed by the end of 1994 all of which will be on rubber bearings [Ref 1.2]. A distinction is drawn betwe

Tests were carried out on a brake lining damper intended to dissipate energy between parts of a structure having relative motion during earthquake attack. The device operates by the sliding of a steel plate clamped against a brake lining. Hysteresis

While quite slender cross bracing may suffice to maintain rigidity in a braced structure under static loading conditions, during an earthquake progressive slackness develops in the bracings, resulting from overstrain in tension, which gives rise to i

Dynamic tests on two lead-rubber bearings, 280 x 230 x 113 mm, are described in which a dynamic actuator was used to apply shear displacements of ±10 to ±140 mm at frequencies of 0.1 to 3 Hz, giving shear strains in the rubber of up to ±200%. The

Simulated dynamic tests in shear on laminated rubber bearings are described. The purpose of the tests was to check the performance of the bearings when used as mounts for base isolating buildings against earthquake attack. Over 1,000 cycles were appl

The history and use of earthquake detectors in New Zealand is described, both for switching on earthquake recorders and for switching off energy sources or equipment in the event of an earthquake. Their use as earthquake alarms, in particular to give
