You will enjoy the procedure of defining your own structure with only several steps and have it analyzed by this StrucMaster. Powerful functions inside can deal with internal force diagram, dynamics, influence line and stability analysis. The Intelligence part can provide detailed solving steps. The MultiSelect command can help you establish the large structure just as in CAD, it can also help designers define structures with non-integer length elements. All of the procedures are done by the artificial intelligence in your iPhone, no matter whether you are connected to the Internet. Convenient, powerful, no delays, what are you waiting for?

Determine capacity of structural steel beam and column easily and obtain results and calculation sheets to double-check your work!! This is a great tool for civil engineers. You will find it useful to calculate capacity of built-up beam and column. The design is in accordance with the provision of AISC 360-16 which is the latest version of design theory. INTUITIVE TOUCH-BASED INTERACTION Quickly place dimensions of the built-up beam or column, and select the steel grade using a simple graphical design. Out solver algorithm will automatically solve and determine the capacity Immediately see what the maximum capacity of the section and also generate calculation sheet to see the calculation details and procedures simultaneously. The calculation sheet will be in .jpg form and automatically saved into your photo gallery. DOUBLY SYMMETRIC AND SINGLY SYMETRIC SECTION AND BUILT-IN MATERIALS Flexible dimensions can be placed to define the size of the section directly. The built-in databases of materials are also provided, including yield strength of 370 MPa, 420 MPa and 500 MPa CONTACT We want to hear from you!! Issues, questions, or requests?
