Effect of Shear Wall Area to Floor Area Ratio on the Seismic Behavior of Reinforced Concrete Buildings

An analytical study is performed to evaluate the effect of shear wall area to floor area ratio on the seismic behavior of midrise RC structures. For this purpose, 24 midrise building models that have five and eight stories and shear wall ratios ranging between 0.51 and 2.17% in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out nonlinear time history analyses. In the analyses, seven different ground motion records are applied to the building models, and the average of the obtained data is used in the evaluation of the seismic performance. Main parameters considered in this study that affect the overall seismic performance of the buildings are the roof and interstory drifts and the base shear responses. The analytical results indicate that at least 1.0% shear wall ratio should be provided in the design of midrise buildings to control the drift. In addition, when the shear wall ratio increases beyond 1.5%, it is observed that the improvement of the seismic performance is not as significant.


Effect of Foundation Soil Stiffness on the Seismic Performance of Integral Bridges
Dicleli, Murat (Informa UK Limited, 2011-05-01)
In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span TB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the TB models are conducted using a set of ground mot...

Çömlekoğlu, Hakkı Gürhan; Burak Bakır, Burcu; Department of Civil Engineering (2009)
An analytical study was performed to evaluate the effect of shear wall ratio on the dynamic behavior of mid-rise reinforced concrete structures. The primary aim of this study is to examine the influence of shear wall area to floor area ratio on the dynamic performance of a building. Besides, the effect of shear wall configuration and area of existing columns on the seismic performance of the buildings were also investigated. For this purpose, twenty four mid-rise building models that have five and eight sto...
Effect of Presoaked Expanded Perlite Aggregate on the Dimensional Stability and Mechanical Properties of Engineered Cementitious Composites
KESKİN, SÜLEYMAN BAHADIR; Sulaiman, Kamaran; Sahmaran, Mustafa; Yaman, İsmail Özgür (American Society of Civil Engineers (ASCE), 2013-06-01)
This paper reports on an investigation of the use of expanded perlite aggregate as saturated lightweight aggregate (LWA) with respect to the mechanical and dimensional stability properties of engineered cemetitious composites (ECC). Expanded perlite aggregate was soaked in water for 24 h before its use in ECC, and replaced 10, 20, and 30% of the aggregate that was used in ECC production. The mixture proportion of a standard ECC mixture with properties that have been extensively reported in the literature is...
Effect of cyclic thermal loading on the performance of steel H-piles in integral bridges with stub-abutments
Dicleli, Murat (Elsevier BV, 2004-02-01)
In this paper, analytical equations are developed to estimate the lateral displacement capacity of steel-H piles in integral bridges with stub abutments subjected to cyclic thermal variations. First, steel H piles that are capable of sustaining large plastic deformations are identified based on their local buckling strength. The normalized moment-curvature relationships of these piles are then obtained for various axial load levels. Next, a low-cycle fatigue damage model is employed to determine the maximum...
Correlation of Deformation Demands with Ground Motion Intensity
Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2008-12-01)
A comprehensive study has been carried out to investigate the correlation between maximum interstory drift demand of frame structures and a number of widely used ground motion intensity parameters. Nonlinear time-history analyses of 16 reinforced concrete frames were performed under a set of 80 ground motion records. The frames were selected to represent features of typical low- to mid-rise reinforced concrete structures. The records contained in the ground motion database were compiled from recorded ground...
