Due to increasing urbanization and rapid infrastructural development, scarcity of land is a problem. Multi-story
structures have been constructed to eliminate this problem. But for the requirement of large service spaces and good aesthetic
appearances, the mono column structural system achieved popularity. Mono column structures are complicated since the mono
column supports the whole structure and all other member acts as cantilevers. Mono column structures are vulnerable to seismic
loads and adding a diagrid structural system on the periphery of the building improves seismic performances. This review paper
aims to review the previous studies on mono column structure and diagrid structural system. It also focuses to review the
performance of different plan geometry buildings.
