Universal serendipity elements with unequally spaced edge nodes

Linear static analysis of large structural models on pc clusters Özmen, Semih; Toker, Kurç; Department of Civil Engineering (2009) This research focuses on implementing and improving a parallel solution framework for the linear static analysis of large structural models on PC clusters. The framework consists of two separate programs where the first one is responsible from preparing data for the parallel solution that involves partitioning, workload balancing, and equation numbering. The second program is a fully parallel nite element program that utilizes substructure based solution approach with direct solvers. The first step of data...
Approximate analysis and condition assesment of reinforced concrete t-beam bridges using artificial neural networks Dumlupınar, Taha; Hasançebi, Oğuzhan; Department of Civil Engineering (2008) In recent years, artificial neural networks (ANNs) have been employed for estimation and prediction purposes in many areas of civil/structural engineering. In this thesis, multilayered feedforward backpropagation algorithm is used for the approximate analysis and calibration of RC T-beam bridges and modeling of bridge ratings of these bridges. Currently bridges are analyzed using a standard FEM program. However, when a large population of bridges is concerned, such as the one considered in this project (Pen...
Displacement-based seismic rehabilitation of non-ductile RC frames with added shear walls Karageyik, Can; Sucuoğlu, Haluk; Department of Civil Engineering (2010) Non-ductile reinforced concrete frame buildings constitute an important part of the vulnerable buildings in seismic regions of the world. Collapse of non-ductile multi story concrete buildings during strong earthquakes in the past resulted in severe casualties and economic losses. Their rehabilitation through retrofitting is a critical issue in reducing seismic risks worldwide. A displacement-based retrofitting approach is presented in this study for seismic retrofitting of medium height non-ductile concret...
Analytical examination of performance limits for shear critical reinforced concrete columns Ergüner, Kamil; Binici, Barış; Department of Civil Engineering (2009) Most of the older reinforced concrete (RC) buildings have columns that are deficient when the current code requirements are considered. Therefore, performance of the columns determines the performance of the structure under the effects of earthquake induced lateral loads. It is recognized that no provision is proposed in TEC2007 to estimate the failure type called flexure-shear. Behavior of columns having probability of failing in flexure-shear failure mode is mostly underestimated by TEC2007 procedures. In...
Operational hydrological forecasting of snowmelt runoff by remote sensing and geographic information systems integration Tekeli, Ahmet Emre; Şorman, Ali Ünal; Department of Civil Engineering (2005) Snow indicates the potential stored water volume that is an important source of water supply, which has been the most valuable and indispensable natural resource throughout the history of the world. Euphrates and Tigris, having the biggest dams of Turkey, are the two largest trans-boundary rivers that originate in Turkey and pass throughout the water deficit nations Syria, Iran, Iraq and Saudi Arabia bringing life as well as water all their way. Snowmelt runoff originating from the mountains of Eastern Turk...
