ÖZBu çalışmanın başlıca amacı; olası bir depremde meydana gelecek hasar ve kayıp olasılıklarını tahmin etmeye yarayan bir hasar tahmin metodu geliştirmektir. Bu amaçla; 11 farklı tip betonarme yapı için hasar olasılık grafikleri elde edilmiştir. Çalışma kapsamında 341 adet betonarme konut binası; yapım yılı, kat adedi ve bina kalitesi gibi ortak özelliklerine göre gruplanmıştır. Toplam 11 farklı bina grubu elde edilmiştir. Binaların tamamı bilgisayar ortamında 3 boyutlu olarak modellenmiş ve her bir bina modeli nonlinear statik itme analizi ile analiz edilmiştir. Ardından, analizlerden elde edilen veriler kullanılarak her bina grubu için 4 farklı hasar olasılığını gösteren kırılganlık eğrileri çizilmiştir. 11 farklı bina grubu için toplam 44 kırılganlık eğrisi elde edilmiştir. Çalışma neticesinde elde edilen eğriler kullanılarak benzer özelliklere sahip binaların yer aldığı herhangi bir bölgedeki olası hasarları tahmin etmek mümkündür.Anahtar Kelimeler: Deprem hasar tahminleri, kırılganlık eğrileri, hasar olasılıkları, betonarme binalar. ABSTRACT Developing Damage Estimation Methods for Different Types of Reinforced Concrete BuildingsThe main purpose of this study is to develop a damage and loss estimation method for predicting earthquake damage in a possible earthquake. For this purpose; damage probability graphs have been drawn for 11 different types of reinforced concrete structures. In the study, 341 reinforced concrete buildings are grouped according to common features such as number of stories, age of the building, construction quality etc. A total of 11 different building groupings were obtained. All of the buildings are modeled by 3-D computer modeling and each was analyzed by nonlinear pushover analysis. Then, fragility curves for 4 different damage probabilities were plotted for each of the building groups using the data obtained from pushover analysis results. Total of 44 fragility curves were Not: Bu yazı -Yayın Kurulu'na 03.11.2015 günü ulaşmıştır.-31 Aralık 2017 gününe kadar tartışmaya açıktır.
Abstract-In this study, the fragility curves were formed for 1 and 2 stories reinforced concrete (RC) residential buildings. The information regarding the structures was taken from projects of the buildings. Nonlinear pushover (NP) analyze was performed to 84 RC buildings which were divided to 2 groups. The buildings built 1998 and later were called Group-A. The building built before 1998 was called Group B. As for nonlinear analysis, a 3D computer model was drawn for each building and nonlinear analyses were applied to these models. Each building was analysed for 2 dimensions (X and Y). Totally 168 NP analysis were performed for each building. 4 damage limits (slight, moderate, heavy and complete) and 5 damage zones (undamaged, slight, medium, extensive and collapse) were determined according to maximum interstorey drift ratio. Fragility curve parameters were obtained at the result of the NP analysis. Probability density functions were calculated with the help of lognormal mean and lognormal standard deviation values of limit states. The fragility curves were generalized for the buildings in Group A and Group B. At the conclusion of this work; 8 fragility curves obtained for 1 and 2 stories reinforced concrete buildings in. Using these 8 curves; damage possibility can be estimated for RC buildings which have same features.
In this investigation an approach buclcling analysis for simply supported rectangular reinforced concrete plates under uniaxial compression are developed.The objective of this investigation is to compare buclcling load of the reinforced plate with circular hole and without hole. A laminated composite plate is considered.The finite element models for with central circular hole and without hole are designed. The composite materials and composite laminates materials approach are discussed. The solution of the problem by computer program coded in FORTRAN is explained and numerical example is given.
Abstract-In recent years, nonlinear calculation methods can be easily carried out by means of developing computer technologies. In this way, comparisons of the nonlinear methods have started to increase rapidly and more studies are carried out on regular and irregular buildings. However, it is most important to compare consistency of the methods on buildings. In this study, most common nonlinear static (pushover) and nonlinear dynamic analysis (time history analysis) methods were compared on an asymmetric planned reinforced concrete (R/C) building. Building having horizontal and vertical irregularities was 5-story. Analyses were carried out by using SAP2000 program. The results are discussed in terms of base shear, lateral displacements and top displacement ratios.
