Streszczenie

The paper analyses the impact of temperature on kinematically admissible failure mechanisms (KAFMs) of energy-active segments of steel halls. The static scheme of segment construction allows the separation of tilt and beam KAFMs and makes it possible to use the probabilistic optimisation of energy-active segments of steel halls. It also allows an optimal division of the structure into the shipment elements and assemblies, and a reduction in thermal impact due to the use of neoprene spacers in the column heads. It was shown that the rational solutions reduce the thermal action on the strain of decisive elements in KAFMs. Additionally, rational coupling of decisive elements in KAFMs increases capacity and reliability of the segments above those recommended in the code [6].
