October 9, 2023
The delayed delivery of LIRA-FEM 2024 and the period for preferential upgrades from previous versions start.
All clients who purchase LIRA-SAPR 2022 software from October 1 to December 1, 2023, will obtain the current version of LIRA-SAPR 2022 with a free upgrade to the 2024 version when it is released.
New options for import of floor plans *.DWG and *.DXF
There are more options to import the floor plans (*.dwg and *.dxf). New features that enable the user to more carefully customize parameters during the import procedure, as well as to create new objects specific to the LIRA-CAD environment.
Enhanced technology for *.ifc import
There are more flexible and fine-tuning settings for the import of object parameters, comparison of materials and cross-sections, assignment of properties of structural elements, and filtering of objects. It means that now the user could specify correspondences between LIRA-CAD object parameters and IFC-object parameters.
Integration with Revit and Tekla Structures
Tekla Structures and Revit-compatible plugins have been adapted for the new version. With the ability to exchange data and models between the two platforms, users may now work even more closely together to enhance collaborative design.
Rhino and LIRA-FEM integration
The LIRA-CAD 2024 plugin is adapted to work in the Rhino 7 (Grasshopper) environment, so the geometry may be transferred from Grasshopper to LIRA-CAD. Due to interoperability between LIRA-CAD and Rhino 7 (Grasshopper), the new features enable engineers to work more productively by applying parametric modelling of buildings and structures to their projects.
The technology of dynamic linking with DWG files is introduced. This means that the user can create all the data for the model and storey in one file, which greatly simplifies the process of making changes and managing the project within a single file. This also reduces the risk of making mistakes while working with multiple files.
A new option to quickly and easily transfer changes from the FEM design model to the LIRA-CAD module. It enables the user to automatically synchronise the LIRA-CAD model with the changes made using VISOR tools, including cross-sections and arrangements of objects.
Object visibility (filter)
The functionality of visibility filter has been significantly updated. It greatly simplifies and speeds up the process of displaying important information. This is a convenient and efficient tool to control visibility depending on object types, with the ability to group objects and customize the display of additional information for both physical and analytical models.
The new options to generate loads distributed over the finite element area. The influence of the load contour on the triangulation mesh is considered. The new options provide a more familiar view of generating loads on FEs, similar to the VISOR design model.
New type of reinforcement for bars - "Wall"
Strength analysis for walls and pylons is based on the linear distribution of deformations in the normal cross-section within the new type of reinforcement, "Wall" (assigned for bars and bar analogues). According to clause 184.108.40.206 of SP RK EN 1998-1:2004/2012, the study of peripheral reinforcement at wall ends is carried out for earthquake design conditions when the "Plastic Wall" mode is activated.
Custom section types in nonlinear analysis
A physically nonlinear analysis of sections from the Cross-section Design Tookit module is implemented, i.e., a cross-section with an arbitrary shape and components may be assigned to a nonlinear bar FE in the design model. Such an element may be step-type, iterative, or iterative with unloading.
Redistribution of masses
A new option to specify a set of mass redistribution groups in elements of the design model for dynamic analysis. This functionality makes it possible to fulfil the requirements of building codes by considering the torsion effects caused by uncertainties in the location of masses and spatial variations in seismic motion.
Rules to modify forces
Sets of drawings
New option to prepare documentation for the pile arrangement and types of reinforcement. Reinforcement types (templates for the arrangement of rebars in the body of the corresponding RC structural elements) may be exported to a DXF file or placed on drawing sheets as editable tables.
