Analysis of domestic and foreign regulatory and scientific and technical documents in the field of wind influence on buildings and structures that are part of hazardous production facilities

摘要

During the work more than 50 domestic and foreign normative and scientific and technical documents in the field of wind influence on buildings and structures that are part of hazardous production facilities were analyzed. Based on the results of the analysis it was revealed that the current domestic and foreign regulatory and technical documents consider only individual primitives, which forms a complex geometric construction of the structure, but it doesn't provide information on the buildings of a complex spatial structure. It is established that for structures with an increased level of responsibility aerodynamic coefficients should be assigned according to recommendations based on the results of model tests in wind tunnels. It is determined that the analytical calculation by the methods given in domestic documents as well as in foreign ones gives only estimated value of wind load (usually with a large margin). Existing test methods almost do not involve permeable building structures, which are common in hazardous production facilities. It is determined that the analysis of numerical simulation experience of permeable building structures is revealed high labor intensity of this process, increased requirements on computing power, a considerable duration of work, which does not allow speaking on its effectiveness in this case. Based on the analysis Of normative documents and scientific and technical literature, the necessity to develop a methodology for improving an increased level of responsibility buildings and structures safety that are a part of industrial enterprise, based on experimental research in wind tunnels, was identified.
