Living on the Edge

A damaged house perched on the edge of the cliffs above Sumner. The photographer comments, "This house has slowly gone over the edge since the big earthquake in Christchurch in February 2011. Subsequent earthquakes has caused the rock face to crumble more and more".

Velocity dependence of HF2V devices using different shaft configurations

Research papers, University of Canterbury Library

High-Force-to-Volume lead dampers (HF2V) have been recently developed through an experimental research program at University of Canterbury – New Zealand. Testing of the device and applications on beam column joints have demonstrated stable hysteretic behaviour with almost no damage. This paper reports testing of HF2V devices with straight, bulged and constricted shaft configurations subjected to velocities of 0.15 - 5.0mm/s. The effect of the shaft configuration on the hysteresis loop shape, design relationships and the effect of the velocity on the resistive force of the device are described. Results show that hysteresis loop shape of the device is almost square regardless of the shaft configuration, and that devices are characterized by noticeable velocity dependence in the range of 0.15-1.0mm/s.
