Title of the articleTower structures design with the required level of security
Abstract.The basic idea of the article is to use numerical probabilistic – statistical methods in designing of tower structures, because of the limitations of the limit states method. The first one does not give any information about reliability of designing building structure and in the second one – there are only two groups of limit states. Therefore, for reliability assessment it is proposed to input the third limit state where the tower structures will be calculated in terms of its safety for humans. The reliability level is limited by the security of not less than 1,2*105. Reliability for the first and the second group can set the customer himself. The article generated by statistical modeling stochastic set of parameters (wind load, ultimate strength steel, yield stress of steel, coefficient of working conditions). Then analyzed the effect of these parameters on the cross section size of the tower construction elements, depending on the specific reliability level in the amount of: 0,99; 0,999; 0,9999; 0,99999. The result of article is a new approach to the appointment of sectional dimensions to the required reliability level.
Keywords.Reliability, security, statistical and probabilistic methods, tower structures, limit states.
