“…The numerical analysis of the G+4 residential setback building located in zone V is carried out for the equivalent static force method, response spectrum method and time history method and compared the results for various response parameters. The columns of setback buildings at the higher slopes are subjected to higher bending moments so they adopted three mitigating techniques such as the OGS models modified using shear walls, magnifying the OGS columns to 2.5 times of storey forces and replacing the OGS columns with RCFSTC and found the use of RCFSTC in the place of ordinary RC column at OGS as the best way (Ghosh & Debbarma, 2017). The Analysis of setback step-back 10,15 & 20 storied buildings resting on sloping ground ranging from 0°, 10°, 15° and 20° for zone IV and medium soil is carried out.…”

An increase in economic growth, as well as urbanization in the hilly areas, encourages the construction in the hilly region. Considering this fact the engineers should assure the safety of constructions in the slopy region. To understand the past attempts carried out on the constructions of the building on the slopy ground the systematic literature survey is done which includes the parameters like types of the building suitable for hilly regions, slope inclinations for safe superstructure in seismic events, types of safety measures recommended to assure the safety of superstructure and necessity of interaction analysis for the constructions in the hilly region. The survey so carried out in the paper gives a fair idea about the research gap and thus motivates researchers to carry out future research on the gap identified. Keywords: soil-structure interaction; slopy ground; bracing system; literature survey; equivalent static analysis; hilly region constructions.

“…Özellikle çekme oranının artması ve çekmenin orta kat veya daha alt katlara doğru oluşturulması durumunda geçiş kat seviyesinde, iç kuvvet değerlerinde ve göreli kat ötelenmelerinde ani artışlar meydana gelmektedir. (Jhaveri, 1967;Chintanapakdee ve Chopra, 2004;Ghosh ve Debbarma, 2017;Demirbaş, 2019). Birçok dünya deprem yönetmeliğinde, çekme düzensizliği ile ilgili düzensizlik koşullarına yer verilmekteyken, Türkiye'de günümüze kadar yayınlanan deprem yönetmeliklerinde çekme düzensizliğine ait açık tasarım koşulları bulunmamaktadır.…”

Döşemeler, katlara etkiyen deprem yüklerini düşey taşıyıcılara aktaran, bu elemanlarının birlikte çalışmasını sağlayan yatay taşıyıcı sistem elemanlardır. Düşey taşıyıcılara oranla yüksek düzlem içi rijitliğe sahip olan döşemeler, rijit diyafram olarak modellenirler. Rijit diyafram modeli, taşıyıcı sistemi düzenli betonarme binalar için uygun çözüm sunmaktadır. Ancak normal katlardan perdelerle çevrili bodrum kata geçiş döşemeleri ile düşey doğrultuda plan alanlarının aniden değiştiği çekme düzensizliği bulunan binalardaki geçiş kat döşemeleri için rijit diyafram kabulünün dikkatle irdelenmesi gerekmektedir. Türkiye Bina Deprem Yönetmeliği (TBDY-2019)’nde geçiş kat döşemelerinin sonlu elemanlarla modellenmesi ve yeterli rijitliğe sahip olduğunun hesapla gösterilmesinin gerekliliği belirtilmektedir. Bu nedenle çalışmada çekme düzensizliğine sahip betonarme bina modelleri üzerinde, rijit diyafram modeli ile döşemelerin esnek davranışını (düzlem içi şekil değiştirmelerini) göz önüne alan sonlu eleman modeli arasındaki farklar incelenerek rijit diyafram modelinin uygulanabilirliği araştırılmıştır. Bu amaçla modellerde, döşemeler rijit diyafram modeli ve iki boyutlu sonlu eleman modeli olmak üzere iki farklı şekilde modellenmiş, mod birleştirme yöntemi kullanılarak analiz edilmiştir. Modeller, modal katkılar, geçiş kattaki yatay ötelenme değişimi, ve gerilme dağılımlarındaki değişimler dikkate alınarak incelenmiştir. Analizler neticesinde sonlu eleman modelinin, incelenen sistemler için rijit diyafram modeline oranla büyük değerler verdiği, ancak aradaki farkın kabul edilebilir limitler arasında olduğu görülmüştür. Analiz süresinde sağladığı avantaj dikkate alındığında yeterli döşeme kalınlığı alınarak rijit diyafram kabulünün incelenen sistemler için uygun olacağı kanaatine varılmıştır.

“…they are exceptionally unpredictable and unsymmetrical in flat and vertical planes Such buildings have mass and stiffness varying along the vertical and horizontal planes; as a result, the centre of mass and centre of rigidity do not coincide on various floors and twisting of structures takes place [2]. Thus, the risk factor of those irregular structures increases abruptly as even the base of those structures becomes inclined at slope [3].…”

This research is an attempt to understand and model the performance of short columns under different ground levels and storey number. This behaviour includes varying axial forced, shear forces, and bending moments under gravity loads. All the results have been taken for the columns at the ground level when the phenomenon of the short column has appeared. To study the performance of short columns under different ground levels and the number of stories, the 3D finite element by sap2000, and multiple linear regression analysis have been used in this study. The results show that the axial force for all types of short columns (internal, edge, corner) increases as the number of stories in the building increases at the same ground level. The effect of changing the number of floors with the same value of ground level is not significant in shear and moment for all types of columns except for the one-story and two-storey buildings. For more illustration, the moment and shear for a building composed of one story is very high compared to the two-storey building where the value becomes significantly low; then become higher again with a 3-storey building and with more stories.
