Loading forms the second step in any structural analysis. After you have constructed a model of the structure you also model the forces or events the structure must withstand. These include things like the weight of the structure itself, the loads from occupants and earthquakes, snow, and wind. While VisualAnalysis does not automatically calculate the required load values (in most cases) or automatically generate those loads, it does provide tools to make load application easy.
- Load Cases: What they are and how to use them. Load Case Manager
- Static Loads: Types of loads available, including ASCE 7 Wind loads, and how to apply them.
- Dynamic Loads: Nodal mass, dynamic response
- Working with Loads: Apply, Find, Edit, Copy, Scale, Delete
- Response Spectrum Generator: Create design spectra per IBC
- Moving Loads: Trains, cranes, and automobiles.
- Time History Loads: Forcing functions, seismic events, harmonic loading
- Live Load Paterns
Response Spectrum Generator
This tool allows you to view, create and store design spectra according to either the UBC 97 or IBC 2003, or IBC 2006 criteria. The spectral data you generate is saved a Spectrum.txt file for later use in Dynamic Response load cases in VisualAnalysis. To access this tool choosefrom the main menu bar in VisualAnalysis.
