RELIABILITY ANALYSIS OF STRUCTURES

Abstract. The process of building an object consists of planning, design, construction, use and eventual demolition [1]. In each of these components in the process of building uncertainties occurs, which can be caused by human or natural effect. Human cause of uncertainties includes intentional and unintentional deviation from the optimal realization, the use of inappropriate materials, unverified construction methods, poor quality of connections between elements, changes to the building design without the consent of all parties. Natural effects are often unpredictable. Reliability is the ability of the structure to meet the construction requirements set out under specific conditions during the service life, according which it is designed to [2]. It refers to the carrying capacity, serviceability and durability of construction and according to them different degrees of reliability can be defined. One of the best ways of presenting the size of the uncertainty in the theory of reliability is the reliability index . Key words: service life, structure, uncertainties, reliability, reliability index
