Update 1 for LIRA-SAPR 2019 R1

June 7, 2019

Update 1 for LIRA-SAPR 2019R1 is available. The following items are updated: collection of loads, analysis of reinforcement, analysis of beam with variable section, export of forces, plugin with Grasshopper, loads, soil model, staircases and design of elements in SAPFIR-RC module etc.

  • Modified option: collection of nonunfirmly distributed load from triangular finite elements of thick slabs and from triangular plates with modulus of elasticity equal to zero.
  • Clarified: overall dimensions of the model with account of punching shear contours in the mode of new graphics (based on DirectX) in problems with punching shear analysis.
  • Restored option to preview combinations of forces when you display information about node and click Combinations button in the dialog box.
  • For the large design models, when you work with the lists of coupled DOF or PRB, time for selecting such groups on the model is considerably reduced. 
  • Modified: analysis of reinforcement by DBN B.2.6-98:2009.
  • Modified: when set of forces for elements of RC structures is exported to local mode of reinforcement, all DCL values are exported properly.
  • (Local mode of reinforcement) added option to sort and renumber rows with design combinations of loads.
  • Modified options to edit and preview stiffness for the steel beam with variable cross-section.
  • Restored: analysis of channel section and C-shaped section by SP 16.13330.2017.
  • Modified analysis of steel beam with variable section in case finite elements are united into structural element.
  • Corrected: account of coefficient mkr during check/selection of steel sections subject to earthquake load.
  • In iterative improvement (clarification) of stiffness parameters of soil and loads on piles by soil model, design computations are not carried out at intermediate iterations. 


SAPFIR-Structures

  • Added option to direct linear and concentrated loads along the vertical or perpendicular to the plane (in this case - the plane of generation).

  • Modified plugin with Grasshopper: new option (in Grasshopper environment) to generate openings in walls by points, lines and contours (nodes: window and door), and openings in slabs by contours (node: slab).
  • Added option: sign variability is automatically assigned to earthquake loads.
  • Cancelled visualization of soil model on the floor plan.
  • Enhanced algorithm for assigning (automatically) Pz on floor slabs. Pz is assigned to all foundation slabs in the project.
  • Added visualization of soil model on sectional elevations.
  • Corrected: LIRA-SAPR program failure when you tried to Generate fragment in SAPFIR.
  • Corrected: program failure when you opened previous files (version 2016 and earlier) in which there are staircases.

SAPFIR-RC

  • Removed: incorrect warning about not adequate reinforcement at zones AS1, AS2 (for column design).
  • Enhanced option: import of mosaic plots of reinforcement.
  • Corrected error in design of an instance of unified group of slabs during subsequent work session with the file.
