Investigation into Behavior of Tall Building Using Belt Truss and Outrigger Systems to Control Deflection

Akshay A. Khanorkar, Shruti Sukhdeve, S. V. Denge, S. P. Raut


In this paper, the comparative study was carried out to compare the use of belt truss and outrigger in tall building to control deflection. To this end 40-storey analysis model structures composed of reinforced concrete core walls with flat slab were prepared. Models are individually analyzed with outrigger and belt truss. The static wind and earthquake analysis on building models showed that first and second optimum position of belt truss as well as outrigger was same and the third position of outrigger and belt truss was different. Based on the analysis results it was concluded that the belt truss was efficient as that of outrigger to control deflection in tall building subjected to lateral loads.
