Methodology for assessing the risks of dangerous climatic phenomena for buildings and structures

Introduction. A general approach to risk assessment of dangerous climatic phenomena, including hydrometeorological loads and actions on buildings and structures, is considered. The analysis of the main criteria for the development of basic parameters of loads, actions, and environmental influences in order to ensure the required reliability and safety is presented, as well as ways to further improve regulatory documents on their accounting.

Aim. To study dangerous climatic phenomena and develop methods for assessing climate risks for buildings and structures; to improve the principles of rationing in the field of loads and actions based on the formation of common approaches to the methodology of transition to parametric rationing in construction in the Russian Federation; to optimize the design of buildings and structures and increase their economic efficiency.

Materials and methods. Based on the analysis of the data available in the regulatory, scientific and technical literature, a general methodological approach is proposed and ways to solve some important tasks of risk assessment and consequences of dangerous climatic phenomena for buildings and structures in a changing climate conditions are outlined.

Results. An engineering methodology for climate risk assessment for buildings and structures under the influence of major climate threats is proposed, taking into account meteorological and technical monitoring data based on climate hazard indices.

Conclusions. In order to formulate the basic requirements for risk assessment and vulnerability of buildings and structures under dangerous climatic conditions, first of all, it is necessary to classify them, establish critical values of their design parameters, and to determine which structures they primarily affect. The developed methodology will make it possible to take into account the permissible damage to buildings and structures from dangerous climatic phenomena, taking into account the severity of the consequences, and to develop requirements for the protection of load-bearing structures of buildings and structures from dangerous climatic processes and phenomena.
