Assessment of Ponderability of Parameters of Platform Joint on Reliability by Method of Linearization

In the process of the study of platform joints of panel buildings, it was established that the most significant contribution to the reliability of the joint is provided by a number of parameters which have specialty randomly. The distribution of these parameters is described by a normal principle that does not have a simple numerical solution. To determine the probability of failure of the connection in the conduct of probabilistic calculations, method of linearization is used, which is based on the method of expanding the initial function in a Taylor series. The work assesses the impact of structural parameters of the horizontal platform joint of panel buildings on the reliability of the connection. The coefficients of ponderability of the investigated parameters are determined in estimating the probability of joint failure. The practical value of the obtained research results is to increase the reliability of the node of interface panel.
