cColumn is a powerful Windows program designed specifically for structural engineers to perform axial-flexural analysis and design of concrete columns, as well as beams and shear walls, according to ACI 318-14/11/08/05/02 and ACI 318-99. It analyzes the uniaxial or biaxial bending capacity of multiple sections of regular shapes (rectangular, round, Tee, I, L) and generic shapes (with openings) simultaneously in an accurate, fast, and user-friendly manner. Multiple load sets may be inputted and checked against section capacities. It features tabulated strain-P-M at every user defined neutral axis step, 2D P-Mx and P-My interaction diagrams, and incredible 3D P-Mx-My interaction surface.

OpenGraph Library (SDK)


OpenGraph Library (SDK) is a powerful 2D and 3D visualization and charting software tool. It is built on the industrial strength OpenGL. The library shields you from the need to learn the complex OpenGL API, and makes it easy to setup impressive and interactive graphics such as zooming, panning, selecting, etc. This library is especially suitable for building scientific, engineering, and financial software applications. You can use the API to develop your custom software… Royalty-Free! Both C++ and .NET binary libraries, and source code are available. We also provide many examples illustrating the use of this library including Win32 Window, MFC Dialog, MFC Document-View architecture, WinForms Dialog, WinForms Window, and WPF Form.

double128 Math Library (SDK)


double128 Math Library (SDK) is 128-bit quad-precision math library that implements approximately 32 decimal place floating point arithmetic for Microsoft Visual Studio. The library includes a new floating point type double128 and a list of corresponding standard math functions such as sqrt(), pow(), sin() etc.. The implementation of the library is based on Intel C++ Compiler _Quad data type.
