Abstract
The present study considers the problems of stability and reliability of truss structure susceptible to stability loss from the condition of node snapping. In the reliability analysis of structure, uncertain parameters, such us load magnitudes, the axial stiffness of bars, coordinate nodes are represented by random variables. Random variables are not correlated. The criterion of structural failure is expressed by the condition of non-exceeding the admissible load multiplier. In the current paper only the time independent component reliability analysis problems are considered. The Hasofer–Lind index in conjunction with transformation method in the FORM was used as a reliability measure.
