Development of Earthquake- and Landslide-Proof Public Buildings and their Transformation into Shelters in Case of Emergency Emmerich Simoncsics Institute for Architecture and Design, Vienna University of Technology, Karlsplatz 13, 1040 Vienna, Austria (simoncsics@tuwien.ac.at)

Abstract
Due to the occurrences of the Niigata-Chuetsu earthquake 2004, last October the Vienna University of Technology already delivered proposals concerning the reconstruction and future disaster mitigation for the protection of the people in the Niigata prefecture. Humane accommodation for the victims should be provided in public buildings, which are earthquake- and landslide-resistant, as well. Last year a selection of earthquake and landslide resistant public buildings have been designed in interdisciplinary cooperation between students of architecture and experts for structural engineers, dealing with projects of tourist facilities, schools, sports and health centers, buildings for research, congress and administration centers with exhibition areas. The buildings have a regular function in “normal case”, but each of them can be converted within 6 (six) hours into a shelter for 2,000 victims in case of emergency, providing humane accommodation and board for several months. Integrated are emergency hospitals, storages, water reservoir and energy supply. So-called “familystands” (3 × 3m), which can be easily assembled, can accommodate six persons each (in three levels, like in a train for overnight trip). The experiences show that emergency accommodations should be made possible in all kinds of public buildings in hazard-prone countries like Japan. Regarding the “Reconstruction Activities”, according to the future demands, the economical development of the Niigata prefecture shall be enhanced by the above proposed buildings. This year, therefore, covering the topic of “Strategy for Disaster Mitigation”, additional public facilities with various functions will be developed and concerning the theme of “Risk Management” the organization of immediate medical aid (emergency hospitals) and the procedure of quick accommodation (transformation of the buildings and transportation of victims) will be treated. It is intended to show the research results in the framework of a poster exhibition. Keywords: Niigata, earthquake, landslide, reconstruction, disaster mitigation,

Introduction
The engineer has the task to do research in the field of natural sciences and to find the truth about the violating forces of Nature. He has to detect the danger for human beings and call the society’s attention to the risks. Moreover, the engineer (including the architect) is supposed to propose practice oriented solutions in order to reduce the hazards and the politicians together with the engineers are responsible to realize the relevant countermeasures in order to protect the population from catastrophes. However, close cooperation with the public is necessary, as well. The truth is that no engineer can stop earthquake and they will occur also in the future. Therefore, necessary preparations have to be done. Expectancy of life may increase in the future. After forty years it might be even 90 years. The last repeat of an earthquake in Niigata was after 40 years (1964–2004). It is not impossible, that an earthquake may happen after 40 years again. Considering the life expectancy, people of even 50 years old today, living in Niigata, may once more experience an earthquake. Based on this awareness, “middle-aged” and younger engineers and politicians are responsible for the protection of human life and property. In the framework of this symposium we exchange our experiences and thoughts about possible improvements of the present situation. How does future look like? “Future” is a very important concept in this connection. We cannot create improvements for the future with our present attitude toward...
