Investigation of Nonlinear Displacement and Deformation Damage Limits of Reinforced Concrete Square Columns According to ASCESEI 41-17
Öz: The seismic performance of reinforced concrete columns is related to the expected damage limits under seismic loads and how this damage relates to safety of the structure. Accordingly, the estimation of reinforced concrete columns deformations become more critical than the estimation of internal forces since the deformations in the post elastic regions of the structure are well correlated with damage in these regions. In order to assess the performance of reinforced concrete columns under seismic loads, performance-based displacement and damage limits are proposed by certain codes. Adequacy of the displacement and damage limit levels given in the code such as ASCE/SEI-41 (2017) were evaluated by carrying out parametric studies for reinforced concrete columns. Reinforced concrete square columns are designed in parametric studies to present the effects of various parameters such as concrete compressive strength, axial load levels and transverse reinforcement ratio on performance-based damage limits. Performance limits corresponding to each performance levels obtained by ASCE/SEI-41 (2017) seismic code were compared. It is concluded that as the axial load levels increases, the damage limits become smaller, the amount of transverse reinforcement becomes more important at these load levels and the limitation stipulated by the regulation is highly effective.

Öz: Betonarme kolonların sismik performansı, sismik yükler altında beklenen hasar sınırları ve bu hasarın yapının güvenliği ile nasıl ilişkili olduğu ile ilgilidir. Buna göre, betonarme kolon deformasyonlarının tahmini, yapının elastik olmayan bölgelerindeki deformasyonlar ile bu bölgelerdeki hasar arasında iyi bir korelasyon olduğundan, iç kuvvetlerin tahmininden daha kritik hale gelmektedir. Betonarme kolonların sismik yükler altındaki performansını değerlendirmek için performansa dayalı deformasyon ve hasar sınırları yönetmeliklerce önerilmektedir. ASCE/SEI-41 (2017) gibi sismik yönetmelikte verilen deformasyon ve hasar sınır seviyelerinin yeterliliği, betonarme kolonlar için parametrik çalışmalar yapılarak değerlendirilmiştir. Parametrik olarak beton basınç dayanımı, eksenel yük seviyesi ve enine donatı oranı gibi tasarım parametrelerin performansa dayalı hasar sınırları üzerindeki etkilerini araştırmak için betonarme kare en-kesitli kolon modelleri tasarlanmıştır. ASCE/SEI-41 (2017) yönetmeliği ile elde edilen her bir performans seviyesine karşılık gelen performans limitleri karşılaştırılmıştır. Eksenel yük seviyeleri arttıkça hasar sınırları azaldığı, enine donatı oranının daha önemli hale geldiği ve yönetmelikte öngörülen sınırlamanın oldukça etkili olduğu sonucuna varılmıştır.
