While the estimation accuracy of the strength of lap splices has been improving, the complexity of design for reinforcement development has progressively increased. This research study investigates the development of a simple and reliable design expression. Equations on development and splices of reinforcement in ACI 318-05 along with other design proposals are critically assessed in light of 203 unconfined and 278 confined beam tests where the splice region was subjected to constant moment. A simple design provision is developed that is based oil a physical model of tension cracking of concrete in the lap spliced region. This new expression is shown to be consistent with current design practice, applicable to existing test results, and simple in application.

Evaluation of the Effect of Functional Similarities on Development Effort Top, Ozden Ozcan; Tunalilar, Seckin; Demirörs, Onur (2008-09-05) Although functional size is the primary input for effort and cost estimation formulas, the relation between functional size and development effort does not always hold in practice. Calculating the magnitude of functional similarity is perceived as a partial solution to overcome this problem. In this study we applied different approaches to identify the magnitude of functional similarity in five projects. The applicability of these approaches is evaluated by observing the impact of functional similarity on e...
Evolutionary algorithms in design Çiftçi, Erhan; Oral, Süha; Department of Mechanical Engineering (2006) Evolutionary Structural Optimization (ESO) is a relatively new design tool used to improve and optimise the design of structures. In this method, a few elements of an initial design domain of finite elements are iteratively removed. Such a process is carried out repeatedly until an optimum design is achieved, or until a desired given area or volume is reached. In structural design, there is the demand for the development of design tools and methods that includes optimization. This need is the reason behind ...
Design thinking in urbanism: Learning from the designers Çalışkan, Olgu (Springer Science and Business Media LLC, 2012-12-01) Since the design methods movement of the 1960s, design studies have made significant progress in our understanding of design thinking in general. Nevertheless, urbanism's enduring lack of interest in the cognitive insights of design has caused the field to continue to rely on early procedural models, which have been invalidated by the emerging debates in design studies. The shortcomings of this theoretical condition are proven mainly by the disputable conceptualisations of analysis and design in spatial pla...
Reducing inconsistencies in intuitionistic 2-way adaptive fuzzy control systems Gurkan, E; Erkmen, Aydan Müşerref; Erkmen, İsmet (2000-08-30) Our objective in this paper is to model and reduce inconsistency in expert knowledge for our proposed 2-way adaptive fuzzy system that makes use of intuitionistic fuzzy sets. Intuitionistic fuzzy sets model an interval valued distribution of information in the adaptive control architecture with the necessity at the lower bound as the degree of membership functions and the possibility at the upper bound as the complement of the degree of nonmembership functions. Uncertainty is modelled as the width of this i...
Comparison of 2D and 3D image-based aggregate morphological indices Kutay, M. Emin; Öztürk, Hande Işık; Abbas, Ala R.; Hu, Chichun (2011-01-01) Significant progress has been made over the last two decades in the characterisation of aggregate shape using automated image analysis and processing methods. Aggregate shape characteristics have been quantified using three distinct shape parameters, namely the aggregate form, angularity and surface texture. Several mathematical procedures have been developed to quantify these parameters. For practical reasons, most of these procedures were limited to two-dimensional (2D) and utilised 2D aggregate images. T...
