In this paper, an approximate method is proposed for determining sway of multistory RC buildings subjected to various types of lateral loads. The calculation of both fundamental period and stability index in RC building requires the sway term at each story level. Using approximate method design engineers can estimate sway terms at each story level. The developed analytical expressions are inserted into fundamental period and stability index equations to replace the sway terms, which yields modified equations for fundamental period and stability index without any sway terms. It is fairly easier to employ these equations developed by eliminating all sway terms. Results obtained from the equations are remarkably close to those generated by the related computer program. Consequently, design engineers can reliably use the simple equations to calculate stability index and fundamental period, which enables the determination of these parameters without referring to the complex sway terms. The capability and accuracy of the proposed equations are demonstrated by a numerical example in which computer program results are compared with the proposed methodology.

A simplified method for determining sway in reinforced concrete dual buildings and design applications TEKELİ, Hamide; Atimtay, Ergin; TÜRKMEN, Mustafa (2013-10-25) Sway analyses of reinforced concrete buildings generally are carried out with computer programs. However, as the number of iterative solutions increase, the process may become tedious. This paper proposes a simple analytical method to evaluate sway of dual buildings subject to various types of lateral loads. The proposed method is based on the continuum model. Story drift limited by building codes can be controlled by the proposed method. Likewise, design engineers can use the simple analytical expressions ...
A simplified non-linear procedure for buildings with shear walls TEKELİ, Hamide; Atimtay, Ergin (Thomas Telford Ltd., 2015-01-01) A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to bot...
DEVELOPMENT OF A HAND METHOD TO ESTIMATE FUNDAMENTAL PERIODS OF STEEL ECCENTRICALLY BRACED FRAMES Kusyilmaz, Ahmet; Topkaya, Cem (2016-12-09) This paper describes formulation of a hand method which can be used to estimate the computed fundamental periods of vibration of steel eccentrically braced frames (EBFs). The developed method uses the Rayleigh's method as a basis and utilizes the roof drift ratio under seismic forces as a parameter. The roof drift ratio was obtained from EBF designs by considering different seismic hazard, number of stories, braced bay width, and link length to bay width ratio. A simple expression was developed to represent...
A generalized correlated random walk approximation to fractional brownian motion Coşkun, Buket; Vardar Acar, Ceren; Department of Statistics (2018) The application of fractional Brownian Motion (fBm) has drawn a lot of attention in a large number of areas, ranging from mathematical finance to engineering. The feature of long range dependency limited due to the value of Hurst parameter H ∈ (1/2, 1) makes fBm the desired process for stochastic modelling. The simulation of fBm is also vital for the application in such fields. Hence, the development of an algorithm to simulate an fBm is required in both theoretical and practical aspects of fBm. In this stu...
A modified applied element model for the simulation of plain concrete behaviour Soysal, Berat Feyza; Arıcı, Yalın; Tuncay, Kağan (2022-08-01) A modified applied element model to simulate the behaviour of plain concrete continuum structures including discrete cracking is proposed in this study. In the classical applied element model, Poisson effects are fully ignored. To remediate this issue, diagonal elements are introduced to include the Poisson effect, and the constitutive parameters are rigorously determined using the Cauchy-Born rule and the hyper-elastic theory. The formulation is validated for linear elastic problems and the consistency and...
