DYNAMIC BEHAVIOR ASSESSMENT OF MID-RISE RESISTANT SKELETONS BASED ON THE CONTINUUM MODEL IN NEAR-FAULT

The results of many previous studies have shown that the relative deformation caused by the lateral displacement between successive stories is one of the major factors to evaluate the structural damage. This parameter indicates the correlation between structural response components and seismic damage characteristics. In order to reduce and limit the stories displacement in mid-rise to tall buildings, the use of multi-cell framed tube system can be considered which significantly increases the lateral stiffness of the structure (Alonso-Rodriguez et al., 2015). In this paper, two studied models were designed using separated hybrid and bundled moment framed tube skeletons as 10-story structures. The two studied structures are symmetric and regular with plan and height. The resistant skeleton of these structural systems behaves like a multi-cell rigid tube. The plans of the studied models are shown in Figure 1.
