Progressive Collapse Analysis of a Reinforced Concrete Structure Using the Enhanced Local Resistance (ELR) Method: A Comparison of UFC 4-023-03 and the Turkish Earthquake Code (TEC 2018)

Öz

Disasters cause significant damage to structural elements in the affected regions throughout the service life of buildings. This damage typically manifests as the loss of structural elements or a reduction in load-bearing capacity. Many countries conduct research and publish regulations and analytical methods to minimize such damage. One of the primary references in this context is the UFC 4-023-03 guide, titled "Design of Buildings to Resist Progressive Collapse," issued by the United States Department of Defense. This guide addresses the phenomenon where a structure experiences element loss due to various disasters, potentially leading to progressive collapse. The guide proposes three methodologies for assessing the progressive collapse resistance of structures: the Alternative Path method (AP), the Tie Force method (TF), and the Enhanced Linear Resistance method (ELR). In developing countries such as Türkiye, there are no specific regulations addressing the progressive collapse phenomenon. As a result, structures of critical importance are constructed without such provisions. In this study, a reinforced concrete building was analysed using the Enhanced Linear Resistance method, following the UFC 4-023-03 guidelines and the Turkish Earthquake Code (TEC). The objective is to identify the differences and commonalities between the UFC and the regulatory framework in Türkiye, where structures are not explicitly designed to resist progressive collapse. At the conclusion of the study, shear demand values of structural elements and other relevant parameters were comparatively presented.

Geliştirilmiş Yerel Dayanım (GLD) Yöntemi ile Betonarme Bir Yapının Aşamalı Göçme Analizi: UFC 4-023-03 ve Türk Bina Deprem Yönetmeliği (TBDY 2018) Karşılaştırması

Afetler meydana geldikleri bölgede, yapıların hizmet süresi boyunca yapısal elemanlara büyük zarar vermektedirler. Bu zarar genellikle yapısal eleman kaybı ya da taşıma gücünün zayıflaması olarak karşımıza çıkmaktadır. Birçok ülke bu zararları asgari düzeye indirebilmek için çeşitli araştırmalar ve yönetmeliklerinde ifadeler ile analiz metotları yayınlamaktadırlar. Bunlardan ilki çeşitli afetler sonucu yapının eleman kaybıyla başlayan ve aşamalı göçme ile süreci tamamlanan/tamamlanmayan fenomen için Amerika Birleşik Devletleri Savunma Bakanlığının yayınladığı UFC 4-023-03 ‘Design of Buildings to Resist Progressive Collapse’ kılavuzudur. Kılavuz, yapıların aşamalı göçme direncini belirleyebilmek için Alternatif Yol metodu (AP), Bağ Kirişler metodu (BK) ve Geliştirilmiş Lineer Dayanım (GLD) metodudur. Türkiye gibi gelişmekte olan ülkelerde ise aşamalı göçme fenomenine ait bir düzenleme bulunmamaktadır. Bu tür ülkelerde kritik öneme sahip yapılar bu eksiklikle inşa edilmektedir. Bu çalışmada, betonarme bir yapı örneğinin Geliştirilmiş Lineer Dayanım yöntemi kullanılarak UFC 4-023-03 ile Türk Bina Deprem Yönetmeliği (TBDY2018) esas alınarak analiz sonuçları karşılaştırılmıştır. Bu sayede Türkiye gibi yapıları aşamalı göçmeye karşı direnci bulunmayan ülkenin UFC ile arasındaki farklar ve ortak noktalar belirlenmiş olacaktır. Çalışma sonunda, yapı elemanlarının kesme talebi ve diğer parametreler karşılaştırılmalı olarak sunulmuştur.
