Abstract

Farklı malzeme ve yöntemlerle inşa edilen endüstriyel yapılar, sanayinin gelişmesi ve enerji ihtiyacının artması ile sektörde önemli bir rol oynamaktadır. Endüstriyel yapıların uzun yıllar hizmet verebilmesi için tasarım ve uygulama aşamasında birçok parametre dikkate alınmaktadır. Bu çalışmanın amacı, betonarme endüstriyel bacaların zemin-yapı etkileşimine (SSI) bağlı dinamik davranışını incelemektir. Bu nedenle örnek olarak 1999 Kocaeli Depremi'ne maruz kalan betonarme bir endüstriyel baca seçilmiştir. Farklı özelliklere sahip (sert, orta ve yumuşak) zeminlerin seçilen yapının dinamik davranışına etkisi ANSYS sonlu elemanlar programında lineer zaman alanı analizi ile sayısal olarak incelenmiştir. Analizlerde Kocaeli Depremi'nin (1999) yatay bileşeni kullanılmıştır. Çalışmalar sonucunda yapının mod şekli ve frekansının yanı sıra gerilme, gerinim ve yer değiştirmeler de elde edilmiştir. Zemin ortamının sertliği azaldıkça (sert zeminden yumuşak zemine geçiş), baca tepe yer değiştirmelerinin ve boşluk kenarlarındaki gerilmelerin arttığı gözlemlenmiştir.

Effect of Soil Type on Dynamic Behavior of Reinforced Concrete Industry Chimneys

Abstract

Industrial structures built with different materials and methods play an important role in the sector with development of industry and increase in energy need. Many parameters are considered in the design and application phase of industrial structures to provide service for many years. The aim of this study is to examine dynamic behavior of reinforced concrete industrial chimneys depending on soil-structure interaction (SSI). For this reason, a reinforced concrete industrial chimney, which was exposed to the 1999 Kocaeli Earthquake, was chosen as a sample. The effect of soils with different properties (hard, medium and soft) on the dynamic behavior of the selected structure was investigated numerically by linear time history analysis in ANSYS finite element program. The horizontal component of the Kocaeli Earthquake (1999) was used in analyses. As a result of the studies, besides the mode shape and frequency of structure, stress, strain and displacements were also obtained. It has been observed that as the hardness of the soil environment decreases (transition from hard soil to soft soil), chimney apex displacements and stresses on the edge of the voids increase.
