Abstract
The work presents the design process, analysis and practical evaluation of nodal connections of the beam-column frame of a low-rise building in the BIM design environment for the action of active loads and emergency temperature effects of fire. A study of the use of design tools was conducted. The conduct of such studies is due to the need to increase the reliability of the steel frame in fire conditions and to update the requirements of the normative documents of the Eurocodes regardingthe fire resistance of metal structures. The standard fire mode was considered, the heating parameters ofelements connected in nodes were analyzed. A review of the theoretical foundations of the calculation of steel structures for the high-temperature effect of the working environment showed the feasibility of applying a simplified method of calculation and determination of heating parameters accordingto normative data.Simulated rod diagram of the frame with loads. An analysis of the stress-strain behavior (SSB) ofthe elements under the action of the emergency combination was carried out. 3D modeling of thenode was used for further calculation. The BIM concept is implemented by integrating Robot StructuralAnalysis PC with the IdeaStatica calculation complex. It has been established that the connection ofPC Robot Structural Analysis with the IdeaStatica calculation complex is rational for the design andcalculations of buildings and structures in 3D space and allows using the results of the temperature effect calculation to adjust the structural solution in order to reduce its metal consumption, labor costsand rationalize the reserves of bearing capacity.The presented process of designing frame nodes summarizes approaches to the development of effective structural forms. The use of information models simplified design, optimized work processes, and also made it possible to increase the complexity of nodes both at the level of the designsolution and at the level of the calculation model, taking into account the nonlinear effects of temperature influence.
