I like to remind that lateral restraints only work if the design is controlled by the member stability. If the design still goes for the ultimate strength (i.e. plastic moment capacity) I suggest that any consideration should be placed on increassing the first moment of area of the section. It...
Hi, Im Airil, doing a research on flexural strength of composite beam. Two beams were stiffened by C-channels at the lower flange to increase its ultimate strength. The beam was subjected to two point load, intentional to produce constant moment at the mid-span region. The problem was, due to...
