In renewed SP LIRA 10.4. intuitiveness of input data setting was improved, solution accuracy was drastically increased (factoring in track gauge of moving load ), graphical analysis and results documentation features were added..
As always, the speech of Guram Avtandilovich Dzhinchvelashvili, professor of the "Strength of Materials" department at Moscow State University of Civil Engineering (MSUCE), was deep and academically detailed. In his report «Structural seismic design using Pushover analysis method» Guram Avtandilovich talked in more details about capabilities of SP LIRA 10.4, which allows to evaluate behavior of the structure under seismic actions beyond the elastic limit - Pushover analysis method. This method connects bearing capacity, given as relationship between displacement of top of the structure and shear force in foundation, and seismic requirement given as a response spectrum. Intersection point of bearing capacity curve and response spectrum curve - dynamic equilibrium - is evaluated and it's used for evaluation of expected behavior of the structure.
The report «New capabilities of interaction between SP LIRA 10.4 and Revit Structure, as well as other CAD systems» by «LIRA soft» company technical director Alexey Viktorovich Kolesnikov generated a particular interest. In his speech Alexey Viktorovich made an emphasize on new capabilities of interaction between Autodesk Revit Structure and new SP LIRA 10.4, which allows to use Revit Structure analytical model as SP LIRA 10.4 design model for evaluation of design solutions reliability, followed by calculation results export into Revit Structure analytical model.
Leading design engineer of LLC «IWC «BelEnergoStroy» Alexey Nikolaevich Dvorak told about experience of SP LIRA 10.2 (previous generation of SP LIRA 10.x) use. He told about efficiency of SP LIRA 10.2 utilization as convenient design tool, using specific problem of three-hinged arch truss construction as an example.
«LIRA soft» company leading expert Kanev Danil Valerevich presented report «Advantages of model analysis using SP LIRA 10.2» from expertise's point of view and showed on which parameters the one should pay attention during analysis of the design model; touched on an issues of structural fracture resistance analysis; drew attention to how quickly detect errors in project using finished model; discussed standards of report, delivered to the expertise.
