For a long time earthquake risk was considered unavoidable. It was accepted that buildings would be damaged as a result of an earthquake’s ground shaking. Preventive measures for earthquakes were therefore mostly limited to disaster management preparedness. Although measures related to construction methods had already been proposed at the beginning of the 20th century, it is only during the last decades that improved and intensified research has revealed how to effectively reduce the vulnerability of structures to earthquakes. The objective of this document is to present recent knowledge on earthquake protection measures for buildings in a simple and easy to understand manner.
The chosen method explains basic principles by matching them with illustrations, examples, and an explanatory text. The principles, photographs (from the author or third parties), and the texts are the result of a long research and design activity in the challenging and strongly evolving field of earthquake engineering. The author would like to thank, above all, the numerous photographs contributors mentioned at the end of the booklet, who have made available the results of extensive and often dangerous efforts. Thanks are also extended to the Federal Office for Water and Geology and the Swiss Agency for Development and Cooperation for editing and carefully printing this document. Zurich, December 2002 Prof. Hugo Bachmann
Worldwide earthquakes cause regularly large economic losses - Kobe in 1995 with more than 6000 causalities, counted for 100 Billion US$ of economic loss. Earthquakes are unavoidable. Reducing disaster risk is a top priority not only for engineers and disaster managers, but also for development planners and policy-makers around the world. Disaster and risk reduction are an essential part of sustainable development. On December 11 2000, the Swiss Federal Council approved for federal buildings a seven-point program running from 2001 to 2004 for earthquake damage prevention. The earthquake resistance of new structures is a high priority in the Confederation’s seven-point program. The author of this publication, Professor Hugo Bachmann, has devoted many years to the study of seismic risk and behavior of buildings subjected to earthquakes. At the request of the FOWG, which expresses its gratitude to him, he agreed to make available his extensive scientific knowledge on earthquake resistance of buildings. These guidelines are designed to contribute to the transfer of research results into building practice. These results must be
taken into account by the design professionals, thus ensuring a reasonable earthquake resistance for new structures at little or no additional cost. SDC would like to contribute to the dissemination of knowledge on seismic design of buildings by translating this FWOG publication in English and thus extending its readership among construction professionals. SDC intends to gather available...
