What's Possible

Automate Your Tasks With Flexible, World-Class Software


  • Automatically build structural models

  • Migrate data from other platforms

  • Simple, readable file format

  • Add an interactive rendering of your model

  • Import Sections directly from Section library

  • Save/Load models from cloud storage

Structural Analysis

  • Run FEA on 3D structural models

  • Linear, P-Delta, Buckling, Response Spectrum (and more) Analysis options

  • Members, Cables, Plates, and rigid element types

  • Run Load Combinations and self-weight

  • Commercially tested and verified

Member Design

  • Steel design checks from AISC 360, Eurocode, CSA S16, AS 4100, and BS 5950

  • Reinf. Concrete design checks from ACI 318, Eurocode, AS3600, CSA A23.3, BS 8110, and more

  • Cold-formed steel checks from AISI S100 and AS/NZS 4600

  • Get Wind and Snow Loads from ASCE, AS1170, NBCC and Eurocode

  • Optimize your structure with varying criteria to get the most efficient sections

SkyCiv structural analysis api has a sandbox that helps you test your structural engineering api functions and scripts

Easy to get Started

Test your scripts quickly and easily using the SkyCiv API Sandbox. Paste your code on the left, and run the API. Your results will appear on the right hands screen. Serves as a great introduction to the input and output you send and receive.

Not sure where to start? Load one of our sample scripts to see real examples of how to run analysis, design checks, wind load calculations and more from SkyCiv's API.

Try our API sandbox

Use our Renderer, for Free

Need a 3D renderer for your structure with screenshot and analytical result displays? We've got you covered. Simply embed a Javascript file, and you'll be able to leverage the full capabilities of our 3D web-based renderer. Make the most of:

  • Display your structural model
  • Mouse interactions (create your own click actions)
  • Take screenshots and control view settings
  • Review results and display analytical results
  • Deflect and Deform your structure to review deflection

Commercially Tested Technology

The SkyCiv API is built on the same technology as our web-based Structural Analysis and Design software. This software has been used by more than 10,000 engineers from more than 160 countries worldwide.

SkyCiv also has built in verification and Quality Assurance procedures to ensure the accuracy of our structural analysis and design check software.

Not sure what an API is?

An API (Application Program Interface) is the ability to connect to our software directly, without going through the user interface. Simply put, API’s allow users to submit some kind of input, perform an action, and return with a response.

Other industries have been taking advantage of APIs for quite some time: Travel sites that allow you to search for the best flights from a variety of different providers are using the API’s from those airlines to give you that information directly in one location. Without API’s, you would need to go to each airline website individually. With the SkyCiv API, we can use the same concept for structural engineering. From a single click, you can generate a model, run an analysis, design checks and respond with a simple pass/fail result, without the need for any visual or graphical user input.

APIs are driving our industry forward, for faster more efficient structural design.
