Investigating a Combinatorial Lateral Resisting System for Tall Buildings
Abstract In this paper, the effect of a combinatorial lateral resisting system, composed of special truss moment frame (STMF) and outriggers, on the behavior of tall buildings is investigated. Outriggers in conjunction with STMFs form an effective system with a great stiffness as well as strength. The STMFs are efficient in controlling the lateral shear displacement, and the outrigger has a high bending stiffness. Therefore, the combination of these two systems presents an excellent system to reduce both the shear and bending displacements. In addition, damage is confined in the expected elements not carrying out gravity loads. Linear and nonlinear analyses were performed for 10, 20, and 40 stories with different systems in order to estimate the efficiency of the presented combined system. The results indicated that the proposed system has a much better performance than special moment frame system in both linear and nonlinear regimes. According to the results, the combined system reduced the drift ratios as well as increasing ultimate lateral strength. In addition, the energy absorption of the proposed system is increased more than 48% that is a valuable achievement.
