Simulating the non-linear response of reinforced concrete (RC) buildings subjected to a sequence of input earthquake records, is an extremely complex concern in the field of the Earthquake Engineering. Buildings with no symmetry in plan have much more complicated behavior under earthquake effects than symmetric buildings. Torsional irregularity in plan is the main topic of many current researches. In previous decades, considerable amount of numerical and experimental studies have been conducted, but more researches are needed in order to confirm a better understanding of the concept of seismic behavior of these structures. In this study modeling and analyses efforts to simulate the experimental response of a scaled three dimensional reinforced concrete shear wall structure tested on a shaking table, are presented. The model structure is a ¼ scale of a three story reinforced concrete building that has torsion due to plan irregularity and layout of structural walls. In order to simulate response quantities measured for the specimen tested on a shaking table, a series of non-linear time history analyses were performed. This structure subjected to AZALEE shaking table tests in Saclay, France under the project of “SMART 2008” which was led by CEA (Atomic energy agency). The model building was tested under a set of bi-directional synthetic and real ground motions that have varying intensities, peak ground accelerations ranging from 0.1g to 1g. Ground motions were applied sequentially to the specimen, starting with the one having the smallest intensity. Displacements and accelerations measured at different locations on the plan at third story were compared with the numerically computed values in order to check the validity of the Finite Element Model that has been obtained in ANSYS ver.12.1.

Ground motion simulations based on regional input parameters and their impact on insurance premiums: Bursa case Ünal, Barış; Askan Gündoğan, Ayşegül; Kestel, Sevtap Ayşe; Department of Earthquake Studies (2015) Determination of earthquake parameters are required for earthquake resistant design and retrofitting of exsisting structures. There are not many options to obtain earthquake data for regions with no or sparce earthquake recordings. Even though some methods are aplicable to these regions they generate only peak ground motion parameters. For cases that require the full ground motion simulations are necessary. Simulations can also be used for gaining knowledge about source, path and site effects. In this study...
Seismic behavior of semi-precast concrete shear walls Karimi Zindashti, Golnesa; Binici, Barış; Department of Civil Engineering (2016) Successful performance of well-designed and constructed precast concrete elements in earthquake resistant structures, has led to widespread use of these kind of elements all around the world. Fast construction, high quality of precast concrete units and high durability are just a few advantages of these elements to be favored over cast-in-situ structures by engineers, and thus to cause seeking the ways to minimize their disadvantages. The main disadvantage of precast concrete elements in construction is the...
Linear modal combination procedure for structural dynamics Tanışer, Sadun; Sucuoğlu, Haluk; Department of Civil Engineering (2013) Earthquake engineering practice utilizes different analysis procedures in the estimation of seismic demands on structures. These procedures are mainly divided into two groups as static and dynamic procedures. Dynamic procedures are more accurate than the static procedures since they include the entire history of any response parameter during the ground motion. Nevertheless, there are also approximate but much simpler static analysis procedures that overcome high computational demands and inherent difficulti...
Investigation of seismic isolation efficiency for building structures Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016) The main goal of this study is to assess the efﬁcacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of ﬂoors. Speciﬁc to this study, the main parameters employed for efﬁcacy assessment will be the interstorey drift ratio and ﬂoor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
Probabilistic methods for estimating the seismic deformations of underground structures Soyman, Kadir Buğra; Gülerce, Zeynep; Department of Civil Engineering (2018) In seismic design of underground structures, simplified semi-deterministic methods based on the stiffness of the soil and the underground structure are used to estimate the seismic deformations. Generally, peak ground acceleration (PGA) value for different hazard levels are provided by the probabilistic seismic hazard assessment (PSHA) analysis, but a single (and deterministic) PGA value is employed in deformation calculations. The objective of this study is to propose a fully probabilistic framework for es...
