Easily determine seismic parameters and loads according to ASCE 7 using ClearCalcs Seismic Analysis calculator.

Seismic analysis to American standards ASCE 7-16

Determine seismic design parameters to ASCE/SEI 7, Minimum Design Loads and Associated Criteria for Buildings and Other Structures as part of the US building codes requirement.

Easily input seismic coefficients and site class for your seismic load analysis

Easily input your Site Class, Site Coefficients, and Seismic Design Category with ClearCalcs' clean and easy-to-use interface.

Seismic design and support for multi-storey buildings

The ClearCalcs Seismic Analysis Calculator supports multi-storey buildings complete with diagrams outlining the seismic base shear lateral force acting on the building.

Member selector tool to easily input your seismic force resisting system

Choose from commonly used seismic force-resisting systems such as Bearing Wall, Building Frame or Cantilevered Column Systems with color-coded utilization checks for easy reference.

Check base shear and building height limit at a glance

Easily view how the base shear is vertically distributed with the Equivalent Lateral Force procedure applied and understand the building height limits for applicable seismic design category.

With spreadsheets and clunky software

Frustration, fuss, and fragile formulas—the old way of engineering calculations that holds you back.

Struggle with endless spreadsheets and custom formulas.

Building codes change, but outdated software and spreadsheets don’t.

Triple-check and verify manual input at every turn.

Old software feels like a maze, with unclear settings, limited templates, and rigid interfaces.

How it works

Your code-compliant calculator

Tired of complex calculations? ClearCalcs Calculator Library keeps it simple, secure, and code-compliant—so you can calculate with confidence.

Save time with ready-to-use templates for wood, steel, and concrete

ClearCalcs offers an extensive library of easy-to-use calculators for beams, columns, and footings, designed to make structural calculations simpler and faster.

Choose from a wide range of pre-configured beam and column options, complete with automatic member sizing, so you can quickly reach reliable designs and reduce rework.

Beams

Columns

Foundations

Walls

Loads

Dynamically track your load paths from roof to foundation

No need to copy and paste reactions between calculations! If the top calculator's reactions change, the loads being inherited onto the lower calculator will update automatically. This includes all loads such as dead, live, snow, seismic, and wind.

Submit professional reports for permit review

ClearCalcs is not only easy to use, but also easy to check! All calculations follow an easy to understand traffic light check system, with multiple levels of detail available giving you the choice of printing every step of the calculation and all code and standard references, or simply a compact, one-page print out.

Report heading includes your project name and address
