SteelBlaze Steel Design Library (SDK)


SteelBlaze Library (SDK) is a powerful steel design API (Application Programming Interface) to calculate section capacity of AISC sections. It is based on the solver engine in our sCheck steel analysis and design software. You can use this reliable and user-friendly API to develop your custom software royalty-free. SteelBlaze is available in both 32-bit and 64-bit, with easy-to-use C++ and .NET interfaces (binary and source code).


Key Features

  • Check the capacity of any of the standard AISC shapes (W, M, S, HP, C, MC, L, WT, MT, ST, 2L, HSS, PIPE) against a set of load effects.
  • Design and select optimal standard AISC shapes against a set of load effects.
  • Consider moment magnification for non-sway condition.
  • Auto generate detailed calculation procedures in Word and PDF formats. Please note that a proper Aspose.Words for C++ license is required to use the report feature. For more information, visit Aspose's website at
  • Easy-to-use programming interfaces to define input, solve, and retrieve results for one or multiple sections.
