Comparison of Blast Analysis Methods for Modular Steel Structures
Comparison of Blast Analysis Methods for Modular Steel Structures

Bülent ERKMEN [1]


Patlama yüklerine dayanıklı endüstriyel modüler çelik yapılar ön üretimli ve kolay taşınabiliyor olmalarından dolayı patlama riskinin yüksek olduğu yerlerde yaygın olarak kullanılmaktadırlar. Bu yapıların sistem elemanlarının patlama yüklerinin etkisi için tasarımında ve analizinde genelde basitleştirilmiş eşdeğer tek serbestlik dereceli yay (ESDOF) modelleri kullanılır. Fakat bu yöntem, elemanların dinamik etkileşimini ihmal eden bir yaklaşımdır. Bu çalışmada, iki modülden oluşan prototip binanın patlama yükleri etkisinde yapısal elemanlarında oluşan hasar düzeyi ESDOF ve dinamik etkileşimin ihmal edilmediği daha güvenilir sonuçlar veren sonlu elamanlar yöntemleriyle belirlenmiştir. Sonuçlar, yapısal elemanlarda oluşan patlama hasarlarının belirlenmesinde ESDOF yönteminin sonlu elemanlar yöntemine oranla yeterliliğini belirlemek için kullanılmıştır.

Two blast analysis methods widely used are three-dimensional finite element (FE) and uncoupled equivalent single degree of freedom (ESDOF) methods. The uncoupled equivalent ESDOF method, which is the most common blast analysis method, provides considerable advantages and simplicity in analysis and design stages. However, the inherent assumptions and simplifications involved but especially neglecting members dynamic interactions can significantly affect accuracy of analysis results. In this study, blast performance of a prototype two-module steel blast-resistant building is evaluated using uncoupled ESDOF and FE methods. The results are compared to evaluate adequacy of uncoupled ESDOF method for blast analysis of the structure.
