  • ANALYSIS: Significant reduction in monopole analysis time.
  • ANALYSIS: ToolTipText displays values when hovering mouse over model design actions.
  • DESIGN: Redefined invalid geometries associated with openings as per AASHTO LRFD LTS-1 from “failures” to warnings.
  • DESIGN: Significant reduction in pad foundation analysis convergence times for cases with 2 or 3 corners in bearing.

CHECKWIND v5.3.0 released

CHECKWIND v5.3.0 is now live and can be downloaded here. New features and enhancements include:

  • Revised warning for automated terrain/exposure detection for tall structures to avoid the software from becoming unresponsive or crashing when using limited hardware.
  • ASCE 7-16: Significant improvements to Topography Factor (Kzt) detection.
  • LRFD LTS-1: Significant improvements to Topography Factor (Kzt) detection.
  • TIA-222-G: Significant improvements to Topography Factor (Kzt) detection.
  • TIA-222-H: Significant improvements to Topography Factor (Kzt) detection.
  • PRESSURES: Internal pressure parameters will be determined based on the selected element type (“STRUCTURAL” or “CLADDING”).

CHECKWIND.API v2 now live

CHECKWIND.API v2 endpoints are now live. New features and enhancements include:

  • Significantly reduced response time.
  • Data is grouped by category (e.g. terrain, shielding, topography).
  • View your request history for a specific day or month with the “/history” endpoint.
  • Return Google’s elevation data to plot your own terrain profiles by adding includeElevationData=true to your request.

The legacy endpoints will continue to work side-by-side with the v2 endpoints for a transition period while existing customers migrate to the v2 endpoints, after which they will be removed.

Here’s an example response generated using the CHECKWIND.API v2 ASNZS1170 endpoint:
