Flexural Strength and Ductility Improvement of NSC beams
In order to calculate the flexural strength of normal-strength concrete (NSC) beams, the nonlinear actual concrete stress distribution within the compression zone is normally replaced by an equivalent rectangular stress block, with two coefficients of α and β to regulate the intensity and depth of the equivalent stress respectively. For NSC beams design, α and β are usually assumed constant as ...
متن کاملDuctility of Confined Concrete
Are structural engineers designing concrete structures with greater capacity and safety than they realize? By exploring effects of confinement in order to incorporate them in usual design procedures of engineering consulting companies, concrete structures will possibly in the future be both stronger, thinner and have a greater ability to deform prior to failure – three properties that are highl...
متن کاملDuctility Evaluation of Prestressed Concrete Members
In this paper, moment-curvature behavior and ductility of prestressed concrete members based on nonlinear analysis is investigated. Influence of various design parameters on ductility of flexural members is determined according to appropriate materials models for stress-strain curves of concrete, prestressing steel and conventional reinforcements. Parameters studied include reinforcing index (ω...
متن کاملModeling of Reinforcement in Concrete Beams Using Machine Learning Tools
The paper discusses the results obtained to predict reinforcement in singly reinforced beam using Neural Net (NN), Support Vector Machines (SVM’s) and Tree Based Models. Major advantage of SVM’s over NN is of minimizing a bound on the generalization error of model rather than minimizing a bound on mean square error over the data set as done in NN. Tree Based approach divides the problem into a ...
متن کاملShear Strength of Slender Reinforced Concrete Beams without Web Reinforcement
This paper attempt to predict the shear strength of high strength concrete beam with different shear span of depth ratio without web reinforcement. The large data base available has been clustered and a linear equation analysis has been performed . The prepared models are functions of compressive strength , percentage of flexural reinforcement and depth of beam. The proposed models have been va...
