Prof. Dr.Saad Ali Hasan

Dr. Al-Taan is a professor who joined Al-Noor University College in January 2022 as head of the Department of Construction Engineering and Project Management. In 1978, he obtained a PhD in Civil and Structural Engineering from the University of Sheffield (UK) under the supervision of Professor Ramanth Narayanan Swamy. After obtaining his doctorate, he joined the Department of Civil Engineering at the University of Mosul with teacher's degree. He received a promotion in 1986 to the degree of assistant professor, and a professorship in 1992. During this period he taught preliminary and graduate studies and supervised postgraduate students. He supervised nineteen master’s students and three doctoral students. He participated in many national, regional and international conferences, and published more than 55 research papers in local, regional and international journals. In 1993, he wrote a systematic book entitled Fundamentals of Reinforced Concrete. From 1985 to 1987, he worked as Assistant Dean for Administrative and Student Affairs, from 2000 to 2001 as Head of the Civil Engineering Department, and from 2009 to 2012 as Cultural Advisor at the Embassy of the Republic of Iraq in Malaysia. In 2015, he was retired and joined the Department of Civil Engineering - Philadelphia University in Jordan until 2019. On the professional level, he worked for more than 30 years in the engineering consulting office of the University of Mosul as a designer and auditor for many projects. Since 2014, he has been a member of the American Concrete Institute (Iraq Branch) and head of the branch in 2016. Since August 2021, he has been commissioned by the American Concrete Institute as head of the committee to translate the American Concrete Institute’s blog for the year 2019 into the Arabic language.

Abstract  :

Fiber reinforcement of cement matrices enhances the tensile strength properties and the stiffness of the resulting composite by controlling the tensile cracking of the material. Various analytical and empirical methods have been proposed to predict the flexural strength of the composite material reinforced with fibers alone. Many of the propl! rties of fiber reinforced concrete can be used to advantage in concrete flexural members reinforced with conventional bar reinforcement. Of all the fibers currently in use to reinforce cement matrices, steel fibers are the only fibers that can be used for long term load-carrying properties. However, only limited data are available on the reinforcing effect of steel fibers when they are used in conjunction with bar reinforcement in structural members failing in flexure. Shah and Rangan'have shown that steel fibers increase, although to a lesser extent than stirrups, the ductility of over …

Abstract  :

A method is proposed to calculate the ultimate shear strength of fibre-reinforced concrete rectangular beams without stirrups. The method shows good agreement with published test results of 89 beams which failed in shear. The published data were also used in a regression analysis to identify the factors influencing the shear strength of fibre concrete beams. These factors were found to be the shear span-to-depth ratio, main reinforcement volume, dimensions, and type. Two formulae are presented to predict the cracking and ultimate shear strength and these show good correlation with published test results.

Abstract  :

A numerical procedure based on the finite element method is developed for the geometric and material nonlinear analysis of reinforced concrete members containing steel fibres and subjected to monotonic loads. The proposed procedure is capable of tracing the displacements, strains, stresses, crack propagation, and member end actions of these structures up to their ultimate load ranges. A frame element with a composite layer system is used to model the structure. An iterative scheme based on Newton-Raphson's method is employed for the nonlinear solution algorithm. The constitutive models of the nonlinear material behaviour are presented to take into account the nonlinear stress-strain relationships, cracking, crushing of concrete, debonding and pull-out of the steel fibres, and yielding of the reinforcement. The geometric nonlinearity due to the geometrical change of both the structure and its elements are also represented. The numerical solution of a number of reinforced fibrous concrete members are compared with published experimental test results and showed good agreement
