Question: Is cracking taken into account for deflection?
Answer: Not all deflection results consider creep and cracking. It is very important that you understand which ones do and which do not. See Load History Deflections .
Question: Does Concept warn if deflection is too high?
Answer: No. Allowable deflection is a very subjective issue and RAM Concept does not warn if deflections exceed conventional limits.
Note: RAM Concept does display a warning when deflections are so large that the analysis itself may no longer be valid. This typically happens for structures that are unstable or nearly unstable. Often the instability is related to unrestrained lateral displacements.
