Abstract
(type = abstract)
Lateral Stiffness is one of the most important properties of a building which not only defines resistance to displacements under lateral loads but it can also have a great impact on natural period of a structure. Different stiffness values can ultimately affect the behavior of a structure under seismic loads and lateral forces that will be applied to it. In this study several parameters that can affect lateral stiffness of shear wall-frame buildings have been studied. At first, different configurations of shear walls in plan were analyzed in both medium rise and high rise buildings. In both cases, models with a central concrete core showed higher stiffness and smaller lateral displacements but at the same time, higher story forces were applied to the structure in seismic analysis. Cracking in shear walls is the other parameter considered in this study. Results indicate that cracked modification factors introduced in ACI can greatly impact the stiffness and other related properties of a building. A more precise approach is used to identify cracked elements based on finite element methods. Openings in shear walls have also been studied. Analysis results showed that in the case considered, openings with an area up to 10% of the wall did not have a significant influence on stiffness of the structure but higher opening ratios eventually resulted into severe loss of stiffness and large displacements. Stiffness of walls not parallel to direction of load is also investigated. Results indicate that even small angles between direction of load and shear wall can considerably reduce the stiffness of a structure in a specific direction. In the end, two parameters affecting flexural capacity of shear walls have been studied, vertical reinforcement and wall thickness. Even though an increase in each of the two parameters can be helpful, results show that each of them can increase flexural capacity of a section more efficiently under different conditions. Analysis in all of the models is performed by ETABS 2013. The intention is not to get involved in too many complex calculations, but rather compare the behavior of buildings in different conditions as a practical guide.
