PROKON® Structural Analysis and Design is a suite of over forty structural analysis, design and detailing programs. The first PROKON programs were developed in 1989, and today PROKON is used worldwide in over eighty countries. The suite is modular in nature, but its true power lies in the tight integration between analysis, design and detailing programs.

PROKON has been improving the lives of structural engineers everywhere for more than two decades.

PROKON Structural Analysis and Design

By Engineers, for Engineers

PROKON is developed and supported by a team of professional engineers and intended for use by structural engineers and technicians. The software provides quick and reliable answers to everyday structural engineering problems:

A collection of geotechnical analysis modules is also available as part of the PROKON suite.


The PROKON suite is modular, yet integrated. Some modules can be used stand-alone, or in conjunction with others. The suite offers a powerful workflow from structural analysis, steel and concrete design, and detailing.

You can use the Concrete Base Design module, for example, on its own or link to it from the Frame Analysis results to have all the design loads entered automatically. Likewise, you can manually detail a concrete footing in Padds, or design the footing in the Concrete Base Design module and have it generate a drawing and bending schedule for you.

Analysis Design Detail Integration

When it comes to ordering PROKON, you can tailor your license to your unique requirements by including only those modules that you really need. You also have the option of configuring two program sets in your license: each set with a unique selection of modules. For example, one set in the license may be geared for the steel designers in your office (e.g. Frame Analysis plus some steel design modules) and the other set for the concrete designers and detailers (Frame Analysis plus some concrete design modules and Padds). This flexibility allows you to minimise your financial expense while still maintaining optimum work flow between team members.

More information



PROKON licenses are available for purchase or annual rent:

  • Annual rental: Programs expire after twelve months. During your rental term, you are eligible to free program updates and technical support. When you renew your annual rental again, you do not need to order the same modules again. The annual rental fee is typically equal to one third of the purchase price. This option provides the best flexibility in your license with minimal initial expense.
  • Purchase: Permanent right to use the software. Free program updates and technical support (collectively referred to as software maintenance) is available for a period of one year. You purchase an upgrade at any time and extend the software maintenance again by another year. The upgrade fee is typically set at 20% of the prevailing price multiplied by the number of years since purchase or last upgrade. For best value, enter into a maintenance agreement—continuous software maintenance at a preferential annual upgrade fee of 15%.

Multi-Workstation Options

Each set of programs ordered has a number of workstations allocated to it. The number of workstations represents the number of computers that can simultaneously access the set of programs. One workstation, for example, can be used on one computer at a time. It can also be installed on a network server and accessed by a single user at a time. Similarly, two workstations can be used on two stand-alone computers, or on a network server and accessed by up to two users at a time.

When ordering multiple workstations, the second and following workstations may be eligible for a discount. With a few exceptions*, additional workstations cost only 50% of the normal price.

*Note: Different pricing structures apply to ProDesk, AutoPadds and products supplied by AutoDesk. Refer to the relevant product pages for more information.
