How to identify Primary and secondary beams


Today’s structural design training and vlog is about a basic structural analysis and design concept pertaining to stiffness.Though many students learn moment distribution method and many analysis methods like the Kanis method,they fail to practically connect what is increase in stiffness. For example a classic text book example says that Inertia of the column is double by two times to 2I but it never corelates that increase in Inertia means bd3/12 is increasing and it can be even an orientation change of the column and necessarily need not be size increase.Since such g
