Abstract
Bu çalõşmada ilgili yönetmeliklere uygun olarak tasarlanmõş 20 katlõ çelik bir bina çerçevesinin lineer olmayan dinamik analizi paralel işlem yoluyla gerçekleştirilmiştir. Dinamik analiz için, Northridge depremi sõrasõnda Newhall istasyonunda ölçülmüş deprem ivmesi kayõtlarõnõn Doğu-Batõ bileşeni dikkate alõnmõştõr. Paralel işlem yöntemi olarak MIGI (Modified Iterative Group Implicit - Değiştirilmiş Döngülü Örtük Grup) algoritmasõ kullanõlmõştõr. İkinci derece etkiler (P-? etkisi) yanõnda malzemenin lineer olmayan davranõşõ da dikkate alõnmõştõr. Bina çerçevesi bir otomatik ayrõştõrõcõ kullanõlarak 2, 3, 4, 5 ve 6 farklõ çözüm bölgelerine ayrõlmõş ve analizler IBM SP süper bilgisayarõnda ve bir SUN iş istasyonlarõ ağõnda gerçekleştirilmiştir. Sayõsal sonuçlarõn incelenmesinden, MIGI algoritmasõnõn doğru sonuçlar verdiği, bunun yanõnda, birden fazla işlemci kullanõmõna izin vererek analiz performansõnõ önemli derecede artõrdõğõ görülmektedir. Ayrõca, işlemci sayõsõ arttõkça analizler çok daha kõsa sürede tamamlanabilmektedir.
In this study, nonlinear dynamic analysis of a 20-story steel building frame designed following the related codes was performed through parallel processing. For the dynamic analysis, the East-West component of the Northridge-Newhall earthquake acceleration record was considered. As the parallel processing algorithm, the Modified Iterative Group Implicit (MIGI) Algorithm was adopted. Along with the second-order effects (P-?), the nonlinear behavior of the material was considered. The building frame was decomposed into 2, 3, 4, 5 and 6 different domains using an automatic decomposer. The analyses are carried out on both an IBM SP supercomputer and a network of SUN workstations. As it is seen from the numerical results, MIGI algorithm produces correct results, and, increases the analysis performance significantly by allowing the use of multiple processors. Furthermore, analyses can be completed in a shorter time as the number of processors increases.
