“…Understanding the nonlinear response and damage characteristics of buildings subjected to significant earthquakes is essential for the assessment of the seismic performance of existing buildings, as well as the safe and economic design of new buildings [1]. Reinforced concrete (RC) columns are the critical members of moment-resisting structural systems and have to be designed adequationuately in strength and ductility [2].…”

Stress-strain and moment-curvature behavior of the reinforced concrete (RC) square columns have been analytically investigated according to different confined concrete models. Figure. Stress-strain and moment-curvature relationships for reinforced concrete columns AimInvestigations of the effect of transverse reinforcement ratio and axial load on the behavior of the reinforced concrete square columns are the main purpose of this study. Design & MethodologyTo better understand the non-linear behavior, information was provided about stress-strain behavior models recommended by the TBEC (2018), Mander et al., (1988), Saatcioglu and Ravzi (1992. Using the proposed models of confined concrete compressive strength of the RC column models were investigated analytically. OriginalityThe literature on the confined concrete models has been reviewed and the stress-strain and moment-curvature relationships of reinforced concrete elements have been calculated according to the current TBDY (2018) regulation. Comparison of the nonlinear behaviors obtained from the TBDY (2018) and the confined concrete models found in the literature has been a current study on behalf of the literature. FindingsThe greatest ultimate curvature values were calculated from the Saatcioglu and Ravzi models (average 24%). In the examination of ultimate curvature values obtained according to the Mander model and TBEC, there is not much difference. There is a negligible difference between the ultimate moment values obtained according to the Mander model and TBEC. It is seen from the results of the analysis that there is not much difference between the stress and strain values obtained for these two models. According to Mander, Saatcioglu and Ravzi models, the average difference value is 3.1% between the ultimate moment values. ConclusionAs a result, it has been observed that when the close to minimum and minimum spacing value, high confined concrete strength values and the ultimate moment values are obtained from the Mander model than Saatcioglu and Ravzi model. These differences are not much between the Mander model and TBEC (2018).

In this study; the effect of the material model, axial load, longitudinal reinforcement ratio, transverse reinforcement ratio and transverse reinforcement spacing on the behavior of reinforced concrete cross-sections were investigated. Squared cross-section column models have been designed. The effect of axial load, transverse reinforcement diameter and transverse reinforcement spacing on the behavior of reinforced concrete column models have been analytically investigated. The behavior of the columns was evaluated from the moment-curvature relation by taking the nonlinear behavior of the materials into account. The moment-curvature relationships for different axial load level, transverse reinforcement diameter and transverse reinforcement spacing of the reinforced concrete column cross-sections were obtained considering Mander confined model. Moment-curvature relationships were obtained by SAP2000 Software which takes the nonlinear behavior of materials into consideration. The examined effects of the parameters on the column behavior were evaluated in terms of ductility and the strength of the cross-section. In the designed cross-sections, the effect of transverse reinforcement diameter and transverse reinforcement variation on the confined concrete strength and the moment-curvature relationship was calculated and compared for constant longitudinal reinforcement ratio. The examined behavioral effects of the parameters were evaluated by comparing the curvature ductility and the cross-section strength. It has been found that transverse reinforcement diameters and transverse reinforcement spacing are effective parameters on the ductility capacities of the column sections. Axial load is a very important parameter affecting the ductility of the section. It has been observed that the cross-sectional ductility of the column sections increases with the decrease in axial load.

Betonarme elemanların eğrilik sünekliğinin doğru tahmini, sismik yükler altında binaların kapasitesinin güvenilir bir tahminini sağladığı için her zaman çekici bir çalışma konusu olmuştur. Bu çalışmada; malzeme modelinin, eksenel yükün ve sargı donatı oranının betonarme kolonların davranışı üzerindeki etkisi analitik olarak araştırılmıştır. Kare kesitli kolon modelleri tasarlanmıştır. Kolonların davranışı, malzemelerin doğrusal olmayan davranışı dikkate alınarak moment-eğrilik ilişkisinden değerlendirilmiştir. Betonarme kolonların farklı eksenel yük seviyeleri ve sargı donatı oranları için moment eğrilik ilişkileri Mander modeli dikkate alınarak elde edilmiştir. Parametrelerin kolon davranışı üzerindeki incelenen etkileri kesitin mukavemeti, süneklik ve etkin rijitlik açısından değerlendirilmiştir. Tasarlanan betonarme kolon kesitlerde, farklı parametrelerin moment eğrilik ilişkisi, sünekliği ve etkin rijitlik üzerindeki etkisi hesaplanarak karşılaştırılmıştır. Eksenel yük ve sargı donatı oranının değişiminin, betonarme kolonların moment-eğrilik davranışı üzerinde önemli bir etkiye sahip olduğu gözlenmiştir. Çatlamış kesitin etkin rijitliği sabit olmasa da sargı donatı oranı ve kesit üzerine etki eden eksenel kuvvet gibi parametrelere bağlı olarak değişmektedir.
