New engineering techniques could help prevent the collapse of existing reinforced-concrete buildings during an earthquake if the work of researchers from Canterbury University in New Zealand goes as planned. The group is studying damage from the recent Christchurch earthquake and using small-scale models of structures and subjecting them to ground-shaking simulations. "We are using any information we can gather in order to improve our solutions and create new ones," said Patricio Quintama, one of the researchers.
