I will check seismic load paths and calculate retrofit forces

Need a clear seismic load path before planning a retrofit? I calculate story forces, diaphragm transfer, collector demand, connection forces, and reactions from your building information.

I provide seismic load path and retrofit force calculations using client supplied plans, dimensions, materials, and existing condition records.

My service can include:

• Site seismic criteria and stated assumptions
• Effective seismic weight and base shear
• Vertical distribution and story forces
• Floor and roof diaphragm transfer
• Collector and drag strut demand
• Critical connection force requirements
• Wall or frame force distribution
• Overturning and foundation reactions
• Load path gaps and discontinuity summary
• Calculation report with controlling cases

This service suits building designers, retrofit contractors, property owners, and calculation reviewers evaluating an existing or proposed lateral system.

Send plans, sections, story heights, floor and roof weights, framing materials, diaphragm openings, lateral-element locations, project location, and prior calculations before ordering. Drawings, site visits, testing, and concealed-condition verification are not included.
