Please, can you explain how program calculates the stiffness factor in 'Required reinforcement' tab. For example, does this program takes into account the creep of concrete? Wiki help says that program takes into account the reological properties of the materials, but after some trials it looks for me, that creep coefficient is neglected. Also, in codes for concrete you can use different stress-strain diagrams to define elastic modulus of the concrete. Here I can't see the possibility to choose something similiar. So, methods of calculation of these stiffness factors are not clear for me.
Sorry for my bad English.
Dear support, please, let me know if you don't have an answer for my question and if there are no information or any examples how robot calcualtes the stiffness factors. I'll not spent my time and i'll try to make hand calculations.
