Influence of outrigger - belt truss on behavior of tall steel buildings with concrete core and circular plan

Lateral displacement is one of the most important factors in the design of tall buildings. Different structural resistance systems proposed for resistance of gravity and lateral loads. One of the appropriate models in tall building design is structural model with concrete core that is the most impor...
