Abstract:

Hexagrid structural system is an innovated system with structural behavior which is similar to a tubular system. In this paper, a numerical study is conducted to estimate the seismic performance of horizontal hexagrid concerning the combined horizontal and vertical hexagrid, tubular and diagrid structural systems. First 30 and 50 story buildings are modeled using ETABS, then pushover and nonlinear dynamic analyses are performed on buildings using PERFORM 3D. Results indicate that the horizontal hexagrid system under nonlinear dynamic analysis has the least roof displacement; buildings capacity curves also demonstrate that the horizontal hexagrid is the most efficient system, as it brings lowest roof displacement along with high energy dissipation.
