MITIGATION OF THE EFFECTS OF VIBRATIONS INDUCED BY HIGH SPEED TRAINS ON SURROUNDING BUILDINGS

Çelebi, Erkan; Kırtel, Osman; Aktaş, Muharrem (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2013)

In this paper, the goal is to primarily deal with the modeling of the railway traffic induced vibrations by using discrete computer models for analyzing related wave propagation problems with soil-structure interaction ...
Non-linear 2-D FE modeling for prediction of screening performance of thin-walled trench barriers in mitigation of train-induced ground vibrations

Çelebi, Erkan; Kırtel, Osman (ELSEVIER SCI LTD, 2013)

The installation of the trench-type barriers can be commonly used in civil engineering applications for isolation of the foundations and structures from the soft ground transmitted vibrations induced by high-speed surface ...
The influence of pore pressure gradients in soil classification during piezocone penetration test

Bol, Ertan (ELSEVIER SCIENCE BV, 2013)

The standard cone penetration test (CPT) measures the resistance at the tip (q(c)) during constant rate of penetration as well as the friction/adhesion along the sleeve (fs). The excess porewater pressures generated as a ...
Neural network based model for seismic assessment of existing RC buildings

Çağlar, Naci (TECHNO-PRESS, 2013)

The objective of this study is to reveal the sufficiency of neural networks (NN) as a securer, quicker, more robust and reliable method to be used in seismic assessment of existing reinforced concrete buildings. The NN ...
Effects of sodium chloride and magnesium sulfate concentration on the durability of cement mortar with and without fly ash

Yıldırım, Korkmaz; Sümer, Mensur (2013)
Evaluation of the liquefaction potential through dissipation measurement in PCPT

Özocak, Aşkın; Sert, Sedat; Bol, Ertan (GEOLOGICAL SOC PUBL HOUSE, 2013)

This paper discusses the interpretation of the pore water dissipation curves obtained during a piezocone test with the prime objective of determining the seismic behaviour of fine-grained soil. The pore pressure dissipation ...
Effects of sodium chloride and magnesium sulfate concentration on the durability of cement mortar with and without fly ash

Yıldırım, Korkmaz; Sümer, Mensur (ELSEVIER SCI LTD, 2013)

This study was carried out on the effect of NaCl and MgSO4 solutions on the mechanical and physical properties of mortars with and without fly ash. Experiments were conducted on the standard mortars and mortars with fly ...
The Investigation of Abrasion Resistance and Mechanical Properties of Self Compacting Concrete Containing Polypropylene Fibers

Uysal, Mücteba; Mh Ozkul; Hn Atahan; Ua Dogan; By Pekmezci; O Sengul (ISTANBUL TECHNICAL UNIV FACULTY CIVIL ENGINEERING PRINTHOUSE, 2012)

Self-compacting concrete (SCC) was first developed in Japan in the late 1980s as a material that can flow through congested reinforcing bars without need for additional consolidation and without undergoing any significant ...
A STUDY OF BIOLOGICAL FILTRATION USING FLOW-THROUGH TRACER TECHNIQUES

Saltabaş, Lütfi (JOHN WILEY & SONS LTD, 1992)

Investigations were performed to determine substrate removal in biological filters with the aid of dispersion theory and first order reaction kinetics. Flow-through tracer experiments were conducted to study the hydrodynamic ...
Subsurface characterization at ground failure sites in adapazari, Turkey

Bol, Ertan (ASCE-AMER SOC CIVIL ENGINEERS, 2004)

Ground failure in Adapazari, Turkey during the 1999 Kocaeli earthquake was severe. Hundreds of structures settled, slid, tilted. and collapsed due in pail to liquefaction and ground softening. Ground failure was more severe ...
The Impact of the HMCFRP Ratio on the Strengthening of Steel Composite I-Beams

Ağcakoca, Elif; Aktaş, Muharrem (HINDAWI PUBLISHING CORPORATION, 2012)

Carbon fiber-reinforced polymer materials have become popular in the construction industry during the last decade for their ability to strengthen and retrofit concrete structures. The recent availability of high-modulus ...
Development of artificial neural network for prediction of salt recovery by nanofiltration from textile industry wastewaters

Eren, Beytullah; İleri, Recep; Doğan, Emrah; Çağlar, Naci (TAYLOR & FRANCIS INC, 2012)

This paper presents the use of artificial neural network (ANN) to develop a model for predicting rejection rate (R-o) of single salt (NaCl) by nanofiltration based on experimental datasets. The rejection rates of NaCl were ...
