Analiz Ayrıntıları¶
Şekil 4.12.1'de gösterilen kısıtlı yüzeyin yer değiştirmesi kısıtlandıktan ve yük düğümüne tekil yük uygulandıktan sonra doğrusal dinamik analiz gerçekleştirilir. Analiz kontrol verileri aşağıda gösterilmiştir.

Analiz Sonuçları¶
Analiz kontrol verilerinde belirtilen izleme düğümünün (yük düğümü, düğüm numarası 3121) yer değiştirmesinin zaman serisi grafiği Microsoft Excel kullanılarak oluşturulmuş ve Şekil 4.12.3'te gösterilmiştir. Analiz sonuçlarının sayısal verileri olarak izleme düğümü yer değiştirme çıktı dosyasının (dyna_disp_3121.txt) bir bölümü de aşağıda gösterilmiştir.
