Abstract (2. Language): 
Storage structures are needed for agricultural products until they are served to markets without any spoilage, damage and lose. For this aim, the storage structures have different cross-section, elevation, and geometric features are designed. One of designed the storage structures is also the silos. Failures are observed in silos due to improper design, operation and maintenance. Deformation, buckling, cracks and collapse are the most common failures observed in silos. Proper design, construction, operation and maintenance can provide longer service lives. In this study, it is emphasized on structural failures observed in agricultural crop silos and some suggestions have been made to the subject.

Abstract (Original Language): 
Tarımsal ürünlerin hasat sonrası bozulmadan ve herhangi bir zarara uğramadan tüketime sunulana kadar muhafazası amacıyla depolama yapılarına gereksinim vardır. Bu amaçla farklı kesit, yükseklik ve geometrik özellikler taşıyabilen depolama yapıları tasarlanmaktadır. Tasarımı yapılan depolama yapılarından birisi de silolardır. Hatalı tasarım, kullanım ve bakım nedeniyle silolarda sorunlar gözlenmektedir. Silolarda gözlenen en yaygın sorunlar deformasyon, burkulma, çatlama ve çökmedir. Uygun tasarım, inşa, kullanım ve bakım daha uzun hizmet süresi sağlayabilir. Bu çalışma kapsamında tarımsal ürün silolarında gözlemlenen yapısal başarısızlıklar üzerinde durulmuş ve konuya yönelik bazı öneriler getirilmiştir.
