“…In the load case 23 one can see that the compressive force N is larger above the "V" columns, whereas the M3 moment above all columns are close to values within the full span, but are of the opposite direction. Their values agree very well with those obtained by Žeželj, [2,5], as shown in Tab. 4.…”

“…s can be seen from the comparison of the results presented here for the complete Finite Element Hall 1 model, and the original ones, obtained by traditional engineering tools, [2,27,28], agreement is excellent both for the main support hoop and inclined columns. This means that the results obtained by Žeželj and his team, who did not have access to complex means of calculation, such as the FEM, are remarkable achievement.…”

“…Thus, in 1983 Zarghamee et al are proposing a design procedure for determining the buckling strength of concrete domes with prestressed concrete edge rings is presented. This procedure was developed using a conceptual model for predicting the buckling strength of concrete domes based on the available literature on stability of spherical shells and creep of concrete [2]. The model is based on the assumption that the dome contains geometric imperfections in the form of spherical caps with different curvature radius.…”

Belgrade fair hall 1 is well known for its dome, which is still the world largest self-supported construction made of pre-stressed concrete, with its diameter of 106 m. In this paper the Finite Element Method (FEM) was performed to analyze different loading and supporting conditions. At the same time, crack growth in a support column was simulated by the extended FEM (XFEM). Results of numerical calculations indicate ingenious design of such a complex structure which was based on “hand” calculation decades ago, without computers. In addition to classical engineering and more advanced numerical calculations, risk based analysis was performed taking into account artificially introduced crack and Failure Analysis Diagram, obtained using stress intensity factor and net stress, as well as fracture toughness and critical stress. This analysis, made for the first time for Belgrade fair hall 1, proved that its structural integrity is jeopardized only when a crack reaches half the thickness of a steel bar.
