The behavior of a sheet pile wall constructed on saturated sand soil and exposed to a distant surcharge load with a finite length at the top of the backfill soil is examined in this study. For this aim, various internal friction angles (φ), and natural ground surface for the groundwater level are considered. Furthermore, it is considered that the sheet pile wall acts as cantilevered and supports a six-meter-high (H) excavation. The simple “45° distribution” (AP) and uniform distribution of “Beton Kalender distribution” (BK) methods are examined with Coulomb’s and Rankine’s earth pressure theories in analytical solutions, while the finite element method (FEM) is used as a numerical method. The present research has two primary goals: a) determining the best analytical approach that provides the maximum bending moment (Mmax) values that are more comparable to those of the FEM b) examining the behavior of the sheet pile wall considering several effects of load scenarios, depth (D) and section type (ST) of the wall, and the soil properties together. In this context, parametrical analyses are performed. Consequently, it is found that the distance of the surcharge load (x1) has a pronounced effect than the intensity (q) and length (Ls) of the surcharge load on the behavior of the sheet pile, and this effect vanishes for the large values of x1. Furthermore, Coulomb theory provides more convenient values with FEM for Mmax than those obtained from Rankine theory. The Mmax values obtained from FEM are generally less than those from BK, while they are greater than those from APC.

“…This developed model was verified through a comparison with the results documented through a laboratory experiment. Furthermore, the finite element analysis was done in various parts of the structure that are more detailed [26][27][28]. The nonlinear finite element analysis was performed to verify the torsional failure collected from the literature as compared to the results of the numerical models with experimental data [29].…”

In this study, a finite element analysis is conducted to study the behaviour of RC beams with different configurations of transverse reinforcement under torsion. These configurations of stirrups are traditional closed stirrups, circular spiral stirrups, and inclined rectangular spiral stirrups. The numerical torsional load values are compared with the experimental torsional load values from previous research. The numerical analysis determined by the ANSYS software shows a reasonable agreement with the experimental torsional load values. The numerical results demonstrate that the use of continuous rectangular spiral stirrups improved the torsional response compared to using another type of beam stirrup. Thus, numerical results show that continuous spiral stirrups are effective at increasing torsional capacity. It is also noted that the behaviour of these beams with continuous spiral stirrups is better than the behaviour of the beams with traditional stirrups. The beams with helical reinforcement, which are TB2, TB3, and TB4 spiral reinforcements, greatly enhanced the toughness. The equivalent stresses are 13.709, 13.728, 14.72, and 15.894 MPa, while the equivalent elastic strains are 0.00421, 0.00377, 0.00347, and 0.00539 mm/mm for the beams TB2, TB3, and TB4, respectively. The beam TB4 had the highest stress and strain value, so its strength improved its ductility properties. As a result, the stirrups' configurations enabled the detection of beam failure mechanisms by improving torsional behaviour when compared to the beam's traditional stirrups. As a result, this research adds more knowledge to the literature on the most effective spiral stirrups for transverse reinforcement to improve the torsional behaviour of beams.

Şevli kazının yapılamadığı derin temel kazılarında iksa sistemi kullanılması, 2018 tarihli “Kazı Güvenliği ve Alınacak Önlemler” genelgesinde zorunlu kılınmıştır. Ayrıca genelgede, 2 yıldan daha az bir süre için bir kazı desteğine ihtiyaç duyulması durumunda iksa sisteminin geçici olarak kullanılabileceği belirtilmiştir. 6 m’den daha düşük kazı derinliklerinin geçici olarak desteklenmesi amacı ile konsol palplanşlar sıkça kullanılmaktadır. Bu çalışmada, geoteknik tasarımcılara kolaylık sağlaması amacıyla içsel sürtünme açısı 24-40° arasında değişen granüler bir zemin içerisinde açılacak 3-6,2 m derinliğinde bir kazı için geçici bir desteğe ihtiyaç duyulması durumunda kullanılacak konsol çelik palplanş duvarların tasarımı ile ilgili grafik ve tablolar oluşturulmuştur. Yer altı su seviyesinin varlığına, konumuna ve zeminin içsel sürtünme açısına bağlı olarak toplamda 14739 farklı kesit incelenmiş ve çakma derinliği, maksimum eğilme momenti ve maliyetler ile ilgili oluşturulan tablo ve grafikler tasarımcıların kullanımına sunulmuştur. Bu tablo ve grafiklerin yardımı ile tasarım süresinin kısaltılması ve maliyet ile ilgili hızlı değerlendirme yapılabilmesi amaçlanmıştır. Ayrıca deplasman analizi yapan paket programların veri girişi aşamasında tasarımcıların duvar boyu için deneme-yanılma sürecine girmeden bu tablo ve grafiklerde verilen bilgileri kullanarak kısa sürede analizlerini gerçekleştirmeleri hedeflenmiştir.
