Dear idecad family, there are formulations that he used while calculating Program Deflection and Crack. Calculation of deflection values; I would appreciate it if you could explain how it calculates through examples of beams, rib beams, slab slabs, and synchronously include these calculation stages in the program's reinforced concrete dialog and report. I needed your help because I couldn't see the deflection calculation in the user manual. I wish you good work.
 
Hi, the sudden deflection values used in deflection are the displacement values obtained from the analysis as a result of G and Q loadings. Based on the moment values obtained from the vertical loads, if the condition is not met, the cracked section inertia values of the elements are found and the analysis is repeated and the sudden deflection values are found once again. Time dependent deflection values and cracked moments of inertia are found with the formulas given in TS500. We can explain the flow diagram of the deflection calculation as follows. As an example, I am attaching an account flow that I made manually and compared with the program. The displacement values in the middle of the beam are found from closed formulas. (Comparison of deflection calculation with example_idecad.pdf) Crack calculation and control are also done based on the formulas given in TS500. (Article 13.3)
