Probabilistic Analysis of Structures Under Snow Load

Abstract

The authors of the article present a model of snow load on the construction of buildings and structures for the territory of Ukraine. This model can be used for others countries of the world. Numeric probabilistic models of snow load have been worked out for PC. The digital snow load model was developed based on observations of many Ukrainian weather stations. This model is implemented as a software package in the programming language C ++. The results of snow load simulation can be used to assess the reliability of building structures. Finally, the implementation of this algorithm will allow to calculate the reliability of a number of existing designs. The received reliability forecasts will allow to reveal potentially dangerous types of building structures and to justify on their basis a proposal to improve Code calculations.

Features of Computer Automation Technology for Building Structures Calculations

“…The above features of the calculation of such structures for predicting their strength and reliability determine the constant need to use the capacities of modern PCs, which in turn requires automation of settlement processes in the form of complete software complexes and systems [11][12][13]. According to the Poltava National Technical Yuri Kondratyuk University Department of Structural and Theoretical Mechanics of the, a number of software tools that implement interrelated tasks for assessing the strength and building structures and their elements reliability were developed [8,10]. Figure 1 shows the global decomposition scheme, which displays that our system consists of four integrated modules: a statistical simulation module of the Monte Carlo method, a module for evaluating the stressed-deformed state under the numerical-iterative finite element method, a module for determining the reliability parameters by statistical processing methods and a module for developing engineering recommendations for the further construc-tion exploitation possibility.…”

“…Under a large number of abandoned buildings, there is an urgent need to evaluate the current quality of structures of these objects in order to predict their strength and reliability, as well as in the development of engineering recommendations for their further exploitation. Considering the necessity of the abandoned buildings reconstruction for bringing them into line with the planned activities, the assessment of their residual bearing capacity, real quality at the time of evaluation and reliability prediction during further possible exploitation becomes extremely [8,10]. Under such terms, the actual question is a detailed study of the structures quality and their reliability prediction in possible further exploitation.…”
