Load Generator and Distributor

The Load Generator and Distributor tool uses the dimensions and load specification for a building to calculate the lateral wind and seismic forces according to ASCE 7 “Minimum Design Loads for Buildings and Other Structures.” The following design codes for development of lateral forces and snow loads are now included in the Load Generator:

  • IBC 2018 and ASCE 7-16
  • IBC 2015 and ASCE 7-10
  • IBC 2012 and ASCE 7-10
  • IBC 2009 and ASCE 7-05
  • IBC 2006 and ASCE 7-05

The lateral forces are distributed between floor levels and the shear walls at that floor level. The method of distribution considers either rigid or flexible floor diaphragms, while considering torsional effects when rigid diaphragms are selected. Output can be exported directly into the X-Brace Shear Wall design module or into an Excel spreadsheet.

The load generator input is split into 5 input tabs including: Building Data, Wind Data, Seismic Data, Snow Data, and Shear Walls Data. The Building Data tab includes the Loading Code, building location and geometry.
