Assessing the Impact of Structural Parameters on the Reliability of a Platform Joint of Panel Buildings by the Method of Statistical Modeling
The development of panel house building in the middle of the XX century addressed the problem of safety of panel buildings at the expiration of their standard operational life. One of the major problems when assessing the reliability of the panel building is the assessment of the reliability of the platform panel joints. Improving methods of inspection and calculation of platform joints is a main way of improving the safety of operated prefabricated buildings. The paper lists the parameters that affect the bearing capacity and initial reliability of platform joints. The probability distribution function, reliability index and failure probability of structures are shown. To assess the influence of design parameters on the reliability of the platform joint, the statistical experiment was conducted. Results of scientific studies and in-place tests with real parameters of designs were the initial data for the experiment. A significant excess of the degree of influence of some parameters on the reliability of the joint has been established; this makes it possible to take into account the experiment results in the practice of design and construction of buildings
