Analytical and Experimental Investigation of Steel Beams Partially ‎Encased in Prestressed Concrete


"After the great efforts and wide researches that have been carried out in the department of Civil Engineering at the BEIRUT ARAB UNIVERSITY and the Lebanese army, it is due to necessity and duty to express my thankfulness to those who supported me. The Army Leadership has a significant participation in supporting all circumstances to get the leaning degree. I would like to express my sincere gratitude to my advisors Prof. Adnan Masry and Assist Prof. Zaher Abou Saleh for the continuous support of my Ph.D study and related research, for his patience, motivation, and immense knowledge. Their guidance helped me in all the time of research and writing of this thesis. I could not have imagined having a better advisor and mentor for my Ph.D study. My sincere thanks also to Prof. Adel ElKordi and Prof. Oussama Baalbaki, who provided me an opportunity to join their team as intern, and who gave access to the laboratory and research facilities. Without they precious support it would not be possible to conduct this research. Last but not least, I would like to thank my family, my parents, my wife, and to my brothers and sisters for supporting me spiritually throughout writing this thesis."
