Effect of Loading and Supporting Area on Shear behavior of Concrete Deep Beams

Abstract

The objective of this thesis is to investigate the effect of loading and supporting area on shear behavior of concrete deep beams, examine the effect of this parameter on size effect of deep beams, and to Study of current design codes procedures and accuracy for predicting shear strength for concrete deep beams. This thesis is carried out with a focus on validating the theoretical data against actual experimental results. All results are compared together to reach a conclusion on how to predict accurately the shear strength of deep beams taking into consideration size effect phenomenon. The thesis is divided into seven chapters. Chapter 1: Introduction This chapter presents an overview of the research that includes introduction, problem statement and motivation. This chapter also provides a description of the main and sub-objectives of the research. Chapter 2: Literature Review The literature review is presented in Chapter 2.The review covers the basic shear theory in beams and deep beams, description of the size effect phenomenon, the main factors that effects shear behavior and size effect, and previous studies done by other researches. Chapter 3: Experimental Work Chapter 3 is describing the experimental program done in this research in details, from materials used, casting procedure to the specimen’s details, and finally the testing procedure.
