Model Uncertainty of Non-Linear Finite Element Analysis of Reinforced Concrete Beams without Shear Reinforcement: Examining the Effect of Modelling Strategies and Modes of Failure

The aim of this thesis project is to investigate the model uncertainty of non-linear finite element analysis of reinforced concrete structures at ultimate limit state by focusing on concrete cracking model, concrete-reinforcement interaction model and mesh size. Following this, eight finite element modelling strategies are developed and 67...

Application of Evolutionary Structural Optimization to Reinforced Concrete Structures

The present thesis has the objective to create a procedure for the automatic preliminary design of reinforced concrete structures, based on the Evolutionary Structural Optimization method (ESO). The developed algorithm performs heuristic topology optimization based on multiple criteria, in subsequent optimization cycles executed in series. In...

Investigation on the attenuation trend of Acoustic Emission in reinforced concrete structures

Considered as an effective real-time monitoring tool, Acoustic Emission (AE) measurements is a promising technology for reinforced concrete (RC) structures. However, its application on real RC structures is still limited. Due to the lack of knowledge on the crack induced acoustic emission in large scale structures.<br/><br/>The aim of this study...

Crack pattern observations to finite element simulation: An exploratory study for detailed assessment of reinforced concrete structures

Uncertainties regarding structural safety of reinforced concrete structures may warrant a need for a detailed assessment. A detailed assessment using nonlinear finite element analysis is one of the alternatives which could help in decision-making about maintaining, upgrading or even demolishing and rebuilding of the structure. A reliable...

The capabilities of the Plaxis Shotcrete material model for designing laterally loaded reinforced concrete structures in the subsurface

A hot topic in the Netherlands is the safety reassessment of dikes. Currently several (river)dikes are being reinforced to withstand a given normative high water level. The environment of those dikes is often characterised by small floodplains and urban areas right next to the dike, wherefore standard geo-technical measures cannot be applied....
