SEISMIC RISK OF CITIES WITH DIVERSE SITE DEVELOPMENT AND WAYS OF ITS REDUCTION
The urban growth of territories results in increasing of economic and social losses in a society from natural disasters. In these conditions there is an important problem of risk assessment and development of preventive measures for reduction of damage from earthquakes of design intensity. For solution of this problem for cities of Uzbekistan the types of buildings by constructive attributes have been classified. It is considered about 30 constructive types of buildings. The estimation of vulnerability of buildings is provided depending on their level of earthquake protection and seismic impact with definition of an average value of damageability index for each constructive type. On the basis of the analysis of seismic risk of the urbanized territories methods of seismic risk reduction which cover three directions of activity of a society are considered: risk assessment and action plan development;physical protection of existing buildings, new construction, lifelines, structural components; measures necessary for risk management.
