Structural reliability analysis of a planar truss in case of limited statistical data

Trusses are common structural elements in many industrial and civil buildings. The article describes the approach to planar trusses reliability analysis case of limited statistical data. proposed can be used when it is complicated determine a cumulative distribution function for design loads physical/mechanical properties material elements. method requires only estimates mathematical expectations standard deviations. also presents equation truss assessment as system result obtained at an interval non-failure probabilities. If resulting too wide decision-making, necessary improve quality data more accurate (non-failure probability).
