Seismic Performance Evaluation of Special RC Frames with Gravity Steel Columns under the Base Level

Abstract: In many multistory buildings, basement levels are used as parking spaces. However, dimensions of reinforced concrete columns at these levels cause them to be unideal parking spaces. An alternative is to replace the RC columns in middle frames with steel columns that are not a part of seismic force resisting system and only support vertical loads, therefore have smaller sections. Using simply supported steel columns under the base level is beneficial not only because they have smaller cross-sections which lead … Show more

“…2-dimensional (2D) models are suitable for buildings with simple plan forms that lack mass or stiffness cross-coupling between orthogonal horizontal directions. Although 2D numerical models are computationally efficient, they are limited to modeling planar structures focusing on a motion in a single plane direction (Zaherdannak et al, 2020). 2D models do not capture the full 3D behavior of structures (Park et al, 2009).…”

“…The aforementioned studies offer methodologies and insight for the quantitative evaluation of seismic damage in three-dimensional structures. Of course, the development of finite element software such as OpenSees 3.5.0 [17] and numerical analysis methods such as incremental dynamic analysis of RC buildings [18,19] also provide a basis for the study. Offering open-source flexibility and a broad range of applications, OpenSees plays a critical role in the precise modeling of complex structural behaviors under seismic loads [20].…”

“…Soil-structure interaction (SSI) is an effective parameter on the results from the structural analyses of the numerical models of structures, including historical masonry towers (Anand and Kumar 2018). In order to simplify the modeling procedure, SSI was neglected in some studies, but the basement level structural elements were modeled (Shabani and Erfani 2020, Zaherdannak et al 2020). Various methods have been presented for considering SSI effects, i.e., modeling springs, dashpots, or the soil layers with solid elements (Çarhoglu and Usta 2018, Fathi et al 2020, Hökelekli and Al-Helwani 2020.…”
