Abstract in English
This research studies the use of outriggers and belt truss system for high-rise composite building subjected to earthquake load, consists of columns (W) and (HP), and beams (W), and central concrete core. Using (SAP2000) in three-dimensional (3D) analysis of building, storey displacements and storey drifts has been compared in four cases:
1. (MWBT): Model without belt truss and outriggers.
2. (MBT2): Model with two belt truss and outriggers at the levels (0.5H, H).
3. (MBT3): Model with three belt truss and outriggers at the levels (0.33H, 0.67H, H).
4. (MBT4): Model with four belt truss and outriggers at the levels (0.25H, 0.5H, 0.75H, H).
Displacements reduction were 41.8%, 67.5%, 75.9%, respectively as compared to a model without any belt truss and outrigger system. So, using outrigger and belt truss system in high-rise buildings increase the stiffness and makes the structural form efficient under lateral load.
