Geotechnical properties of Adapazari silt

Arel, Ersin (SPRINGER HEIDELBERG, 2012)

The geotechnical properties of silts have not been investigated extensively, because they are not found in every soil environment. It is even more difficult to understand the behaviour of silts when they are encountered ...
Non-linear finite element analysis for prediction of seismic response of buildings considering soil-structure interaction

Çelebi, Erkan; Göktepe, Fatih (COPERNICUS GESELLSCHAFT MBH, 2012)

The objective of this paper focuses primarily on the numerical approach based on two-dimensional (2-D) finite element method for analysis of the seismic response of infinite soil-structure interaction (SSI) system. This ...

Utilization of marble dust, fly ash and waste sand (Silt-Quartz) in road subbase filling materials

Fırat, Seyhan; Sümer, Mensur (KOREAN SOCIETY OF CIVIL ENGINEERS-KSCE, 2012)

Large volumes of earthen materials are used in construction each year in Turkey and elsewhere. The wastes generated from these materials can be utilised in various applications including road subbase filling materials. In ...
Determination of the relationship between soil properties and earthquake damage with the aid of neural networks: a case study in Adapazari, Turkey

Bol, Ertan (COPERNICUS GESELLSCHAFT MBH, 2012)

The building stock in the city of Adapazari, Turkey, experienced widespread damage during the 1999 Marmara earthquake. An attempt was made to relate structural damage to the type of subsoil in this study. The Adapazari ...

Non-linear 2-D FE analysis for the assessment of isolation performance of wave impeding barrier in reduction of railway-induced surface waves

Çelebi, Erkan; Göktepe, Fatih (ELSEVIER SCI LTD, 2012)

The establishment of wave impeding barriers (WIBs) beneath the railway track or below the protected residential buildings resting on soft soil can be commonly used to reduce the ground borne vibrations caused by high-speed ...
The influence of coarse aggregate type on mechanical properties of fly ash additive self-compacting concrete

Uysal, Mücteba (ELSEVIER SCI LTD, 2012)

This paper presents the results of an experimental investigation carried out to evaluate the effectiveness of various types of coarse aggregates on fresh and hardened properties of self-compacting concrete (SCC). For this ...
Use of zeolite, coal bottom ash and fly ash as replacement materials in cement production

Yılmaz, Kemalettin; Sümer, Mensur (PERGAMON-ELSEVIER SCIENCE LTD, 2004)

In this research, the effects of zeolite, coal bottom ash and fly ash as Portland cement replacement materials on the properties of cement are investigated through three different combinations of tests. These materials are ...
STRENGTHENING OF HEAT TREATED SLENDER STEEL PLATES WITH GLASS FIBER REINFORCED POLYMERS (GFRP)

Aktaş, Muharrem; Aydın, Emine (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2012)

Steel structural elements face local buckling problems under both bending and axial compressive loads. It is possible to rectify this buckled element by applying heat treatment method instead of replacing it with a new ...
The effect of pre-setting pressure applied flexural strength and fracture toughness of reactive powder concrete during the setting phase

İpek, Metin; Yılmaz, Kemalettin; Uysal, Mücteba; İpek, Mediha (ELSEVIER SCI LTD, 2012)

In this study, the effect of pre-setting pressure on reactive powder concrete (RPC) was examined. The fresh (plastic) concrete samples were filled in a specified beam mould and six different pre-setting pressure values ...
