ZEMİN İYİLEŞTİRME ÖNCESİ VE SONRASI YAPISAL DAVRANIŞ ÜZERİNE KAPSAMLI BİR VAKA ÇALIŞMASI

Öz

Zemindeki yetersiz mühendislik özellikleri sorununu ele almak, özellikle sismik olaylar sırasında yapısal davranışı iyileştirmek ve hasarları azaltmak için çok önemlidir. Bu çalışma, zeminin yetersiz mühendislik özelliklerini, özellikle sismik olaylar sırasında yapısal davranış üzerindeki etkisi gibi kritik bir sorunu ele almaktadır. Bir vaka çalışması metodolojisi kullanılarak ve sorunun önemi vurgulanarak, zemin iyileştirmesinden önce ve sonra yapısal tepkiler değerlendirilmiştir. İyileştirme öncesi için yapılan zemin tepki analizleri, tasarım yetersizliklerini ve zemin sıvılaşmasına eğilimli alanları ortaya koymaktadır. Önerilen çözüm, çimento enjeksiyonu yoluyla zeminin iyileştirilmesidir. Çeşitli deprem senaryoları ve zemin koşulları altında altı vakayı inceleyerek, özellikle Kat Arası Sürüklenme Oranları (IDR) ve çatı sürüklenme oranlarında zemin iyileştirme sonrası önemli iyileştirmeleri vurgulayan 132 dinamik analiz gerçekleştirilmiştir. Bu bulgular, sismik hasarları azaltmada zemin iyileştirmenin etkinliğini vurgulayarak, yapılacak iyileştirmenin yapısal davranıştaki kritik rolünü ve iyileştirilmiş sismik performans için zemin yetersizliklerini ele almanın daha iyi anlaşılmasına katkıda bulunmaktadır.

A COMPREHENSIVE CASE STUDY ON STRUCTURAL BEHAVIOR BEFORE AND AFTER SOIL IMPROVEMENT

Abstract

Addressing the issue of inadequate engineering properties in soil is crucial for enhancing structural behavior and reducing damages, especially during seismic events. This study addresses the critical issue of inadequate engineering properties in soil and their impact on structural behavior, particularly during seismic events. Employing a case study methodology, structural responses are assessed before and after soil improvement, emphasizing the problem's significance. Site response analyses for pre-improvement phases reveal design insufficiencies and areas prone to soil liquefaction. The proposed solution is soil reinforcement through cement injection. Examining six cases under various earthquake scenarios and ground conditions, 132 dynamic analyses are conducted, highlighting substantial improvements post-soil improvement, especially in Interstory Drift Ratios (IDR) and roof drift ratios. These findings underscore the effectiveness of soil reinforcement in mitigating seismic damage, emphasizing its critical role in enhancing structural behavior and contributing to a better understanding of addressing soil inadequacies for improved seismic performance.
