Abstract
In this study, a beam-column element that can be used in nonlinear analysis of reinforced concrete frame systems has been developed. The finite element method has been used to model beam-column elements. Kent-Park's model is also employed to model the confined and unconfined concrete behavior. Geometric nonlinearity is also included to nonlinear analysis using geometric stiffness matrix. The solution of nonlinear equation is solved using an iterative-incremental method that is called "generalized displaced control method." The results obtained from the developed method for two examples are compared with the results of the experiment studies which are available in the literature in order to show accuracy of the program.
Abstract
Bu çaly?mada düzlemsel betonarme çerçevelerin do?rusal olamayan analizinde kullanmak için yeni bir kiri?-kolon elemany geli?tirilmi?tir. Kiri?-kolon elemanyn formülasyonunda sonlu elemanlar metodu ve beton davrany?yny modellemek için ise Kent-Park modeli kullanylmy?tyr. Yapynyn geometrisinin de?i?iminden dolayy meydana gelen lineer olmayan davrany? geometrik stiffness matrisi kullanylarak i?lemlere dahil edilmi?tir. Geometri ve malzeme bakymynda lineer olmayan sistemlerin hesabynda artymsal-yinelemeli metotlaryndan biri olan "genelle?tirilmi? yer de?i?tirme metodu" kullanylmy?tyr. Bu çaly?madan elde teorik sonuçlar MatLab programy kullanylarak kodlanmy? ve literatürde bulunan iki adet deney sonuçlary ile geli?tirilen programyn sonuçlary kar?yla?tyrylarak geli?tirilen yöntemin do?rulu?u gösterilmi?tir.
