This paper investigates the design aspects of Rammed Aggregate Pier® (RAP) treatment as a composite treatment for the unfavourable ground conditions, the construction, QA/QC measures and the verification of the performance via a comprehensive instrumentation scheme. For this purpose, instrumented full scale load test was performed for the stockyard project site in Izmir, Turkey. The soil profile is comprised of fill and soft sandy clay layers overlain by the pyroclastic bedrock. 6 to 18 m long RAP elements were installed in a square grid spaced between 1.5 m and 2.0 m to improve bearing capacity and settlement responses, to accelerate the time rate of settlement (i.e.: consolidation) and to mitigate the liquefaction potential at the project site. The foundation settlement was estimated by RocScience‐Settle 3D software, which was observed to be 30 % smaller than the measured values. After the ground improvement with RAP elements, the foundation settlements were measured as less than 10 cm as compared to 40 ‐ 60 cm settlement predictions of the untreated system.

CPT-Based Assessment of Densification After Ground Improvement with Rigid Inclusions and Rammed Aggregate Piers® (RAP)
Çetin, Kemal Önder; Oner, Lale; Arda, Serhan (2020-01-01)
© 2020, Springer Nature Switzerland AG.Within the scope of this manuscript, the mitigation performance of a composite ground improvement solution, which is composed of 18 m long 40 cm diameter GeoConcrete® Column (GCC) and 50 cm diameter Impact® Rammed Aggregate Pier® (RAP) along with 40 m long 80 diameter piles is assessed by pre- and post-cone penetration testing (CPT). These elements are designed for controlling excessive total and differential settlements, and liquefaction triggering at a paper mill sit...
Seismic performance of gravity-load designed concrete frames infilled with low-strength masonry
Siddiqui, Umair A.; Sucuoğlu, Haluk; Yakut, Ahmet (2015-01-01)
This study compares the seismic performances of two reinforced concrete frame specimens tested by the pseudo-dynamic procedure. The pair of 3-storey, 3-bay frames specimens are constructed with typical characteristics of older construction which is lacking seismic design. One of the specimens is a bare frame while the other is infilled with low-strength autoclave aerated concrete (AAC) block masonry. The focus of this study is to investigate the influence of low strength masonry infill walls on the seismic ...
Performance of seismic-isolated bridges with and without elastic-gap devices in near-fault zones
Dicleli, Murat (2008-05-01)
In this paper, the efficiency of providing elastic-gap devices (EGDs) to improve the performance of seismic- isolated bridges (SIBs) in near-fault (NF) zones is investigated. The device is primarily made of an assembly of circular rubber bearings and steel plates to provide additional elastic stiffness to the SIB upon closure of a gap. The EDG is intended to function at two performance levels under service and maximum considered design level (MCDL) NF earthquakes to reduce isolator displacements while keepi...
Performance comparison of BRBFs designed using different response modification factors
Güner, Tuğberk; Topkaya, Cem (Elsevier BV, 2020-12-15)
This paper presents details of the numerical examination and performance comparison of steel buckling restrained braced frames (BRBFs) designed with different response modification factors, using the next-generation performance assessment approach. Archetypal BRBF designs were conducted following the US provisions and considering response factors equal to or less than the codified limit. The archetypical buildings were subjected to ground-motions acquired from the FEMA P695 Far-Field record-set and scaled t...
Predicted impact of design parameters in asphalt concrete layers on pavement performance
Shakhan, Mohammad Razeq; TOPAL, ALİ; ŞENGÖZ, BURAK; Öztürk, Hande Işık (2021-01-01)
© 2021 ICE Publishing: All rights reserved.The scope of this study was to assess the predicted impact of design factors (voids percentage (Va), effective binder content (Vbe) and aggregate gradation) in each asphalt concrete (AC) layer on pavement performance for conditions in Izmir, Turkey. Research was conducted on three flexible pavement structures for three traffic levels and three subgrade types using AashtoWare Pavement ME Design software. The results indicated that increasing Vbe (from 8% to 15%) and...
