A new approach to determine the base shear of steel frame structures

Çağlar, Naci; Elmas, Muzaffer; Mercan Eryılmaz, Dilek (ELSEVIER SCI LTD, 2009)

Base shear (V) is the maximum lateral force that will occur due to seismic ground motion at the base of a structure. Calculations of base shear depend on a lot of factors such as soil conditions, level of ductility, ...
A new approach to determine the moment-curvature relationship of circular reinforced concrete columns

Çağlar, Naci; Demir, Aydın; Öztürk, Hakan; Akkaya, Abdulhalim (TECHNO-PRESS, 2015)

To be able to understand the behavior of reinforced concrete (RC) members, cross sectional behavior should be known well. Cross sectional behavior can be best evaluated by moment-curvature relationship. On a reinforced ...
A parametric study for distortional buckling stress on cold-formed steel using a neural network

Çağlar, Naci (ELSEVIER SCI LTD, 2007)

The process of prediction of distortional buckling stress of cold-formed steel members is often cumbersome and it is also difficult to perform parametric studies in this field to investigate the effect of geometric parameters ...
A simple formulation for effective flexural stiffness of circular reinforced concrete columns

Çağlar, Naci; Demir, Aydın; Öztürk, Hakan; Akkaya, Abdulhalim (PERGAMON-ELSEVIER SCIENCE LTD, 2015)

In this study, a simple formula as a securer, quicker and more robust is proposed to determine the effective flexural stiffness of cracked sections of circular RC columns. This formula is generated by genetic programming ...
Design of a short tensile coupon for fiber reinforced plastic using artificial neural networks

Sarıbıyık, Mehmet; Çağlar, Naci; Fırat, Seyhan (WALTER DE GRUYTER GMBH, 2005)

The measurement of the mechanical properties of Fibre Reinforced Plastic (FRP) material is necessary for numerical structural analysis and design. The mechanical properties of the FRP materials may be determined by specific ...
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 ...
Dynamic soil-structure interaction analysis of buildings by neural networks

Çağlar, Naci; Elmas, Muzaffer; Sarıbıyık, Mehmet (ELSEVIER SCI LTD, 2008)

In this study, neural networks (NN), which have been widely applied to engineering problems, have been applied to soil-structure interaction (SSI) problems. In the modelling of the NN, the back propagation algorithm has ...
Effectiveness of diagonal shear reinforcement on reinforced concrete short beams

Öztürk, Hakan; Çağlar, Naci; Demir, Aydın (TECHNO-PRESS, 2019)

In the study, an experimental and numerical study is performed to investigate the efficiency of diagonal shear reinforcement (DSR) on reinforced concrete (RC) short beams. For this purpose, 7 RC short beam specimens were ...
Failure analysis of reinforced concrete frames with short column effect

Çağlar, Naci (TECHNO-PRESS, 2009)

Short column effect is cause to failure of columns which may result in severe damages or even collapse during earthquakes. The scope of the study is mainly to reveal the effect of short column on the holistic behaviour of ...
Flexural strengthening of RC Beams with low-strength concrete using GFRP and CFRP

Sarıbıyık, Ali; Çağlar, Naci (TECHNO-PRESS, 2016)

The Turkish Earthquake Code was revised in 1998 and 2007. Before these Codes, especially 1998, reinforced concrete (RC) beams with low flexural and shear strength were widely used in the building. In this study, the RC ...
Forecasting based on neural network approach of solar potential in Turkey

Çağlar, Naci (PERGAMON-ELSEVIER SCIENCE LTD, 2005)

As Turkey lies near the sunny belt between 36 and 42 degrees N latitudes, most of the locations in Turkey receive abundant solar energy. Average annual temperature is 18-20 degrees C on the south coast, falls down to 14-16 ...
Neural network based approach for determining the shear strength of circular reinforced concrete columns

Çağlar, Naci (ELSEVIER SCI LTD, 2009)

The objective of this study is to investigate the adequacy of neural networks (NN) as a quicker, more secure and more robust method to determine the shear strength of circular reinforced concrete columns. In the application ...
