Size Optimization of Steel Using Diaphragm Actions in Vertical and Horizontal Plane

In construction industry, the usage of structural steel in the building has increased and it can also be recycled in the future. The structural members in tall industrial steel buildings like column occupies more space due to larger section size which causes obstruction. In order to achieve economical section size for tall industrial steel building, spacing of columns is ideal, to be chosen with trial and error method for assessing the distance of center to center of column. The bracings system is provided in vertical plane, which will be tied to the major axis of column above certain height in nonusable space and also bracings system in horizontal plane, where both the planes act as a diaphragm. Due to connection in the major axis of column, section reduction will be possible by distribution of forces equally. The members used in bracing system will be of higher section due to distribution of more forces. For this the members of different shapes are used, to find the optimum section for the bracing members. This helps in optimizing the section size of the tall steel building.
