    This paper presents the results of an experimental investigation undertaken to evaluate the seismic performance of reinforced concrete (RC) columns designed for gravity load and confined externally with carbon fiber-reinforced ...
  • Hamad B.S.; Soudki K.A.; Harajli M.H.; Rteil A.A. (FARMINGTON HILLS38800 INTERNATIONAL WAY, COUNTRY CLUB DRIVE, PO BOX 9094, FARMINGTON HILLS, MI 48333-9094 USA, 2004)
    This paper presents the results of two phases of a research program conducted at the American University of Beirut (AUB) to examine the effect of confinement provided by fiber-reinforced polymer (FRP) sheets on the bond ...
  • El-Fadel M.; Aldeen R.A.F.; Maroun R. (, 2004)
    Increased use of diesel engine in on-road vehicles presents a serious health concern, particularly in traffic-congested urban areas. Diesel exhaust contains various gaseous and particulate pollutants, which, at high ...
  • Mabsout M.; Tarhini K.; Awwad E.; Frederick G. (, 2004)
    This paper presents a parametric study of the effect of potholes on load distribution in reinforced concrete slab bridges using finite-element analysis (FEA). Parameters such as the span length, slab width, pothole location, ...
  • Ayoub G.M.; Azar N.; El Fadel M.; Hamad B. (, 2004)
    A study was conducted to assess hydrogen sulphide corrosion in cementitious sewer pipes and concrete culverts existing in the four largest coastal cities and their environs in Lebanon. Significant factors and parameters ...
  • Kaysi I.; Chazbek C.; Ei-Fadel M. (, 2004)
    The potential of intelligent transportation systems (ITS) in alleviating nonrecurring traffic congestion was assessed, and then the resulting implications for vehicle-induced emissions in a congested city in a developing ...
  • Ayoub G.; Saikaly P.; Ei-Fadel M.; Baydoun E. (LARCHMONT2 MADISON AVENUE, LARCHMONT, NY 10538 USA, 2004)
    A study was conducted to evaluate the effectiveness of step-feed in a rotating biological contactor (RBC) system consisting of two three-stage units (one control and one step-feed) treating synthetic wastewater. The ...
  • Ayoub G.M.; Saikaly P. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2004)
    The effect of step-feed and recycling on the efficiency of treatment in rotating biological contractors (RBCs) was investigated. Experiments were conducted on a RBC system consisting of two three-stage units. The two units ...
  • El-Fadl K.; El-Fadel M. (NEW YORK360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USA, 2004)
    Environmental impact assessment (EIA) was devised as a decision tool in response to the grand swell of ecocentric concerns to mediate between the technocentric view of continued development and the ability to create economic ...
  • Metni M.; El-Fadel M.; Sadek S.; Kayal R.; El Khoury D.L. (BASINGSTOKERANKINE RD, BASINGSTOKE RG24 8PR, HANTS, ENGLAND, 2004)
    This paper presents a regional groundwater vulnerability assessment for Lebanon using the DRASTIC model coupled with a GIS-based framework to prioritize protection efforts, whereby the most vulnerable areas to groundwater ...
  • Ayoub G.; Khoury R.; Ghannam J.; Acra A.; Hamdar B. (, 2004)
    A general objective of the study was set at evaluating the feasibility of exploiting the submarine springs in the Chekka Bay, Lebanon, taking into consideration technical, economic, social, and environmental aspects of ...
  • El-Fadel M.; Bsat R.; Adada M. (, 2004)
    Spreadsheets have gained increasing popularity in engineering applications, used by both students and practicing engineers. In addition to their low cost, they are easy to learn, and provide the user with the flexibility ...
  • Bou-Zeid E.; El-Fadel M. (OXFORDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2004)
    This paper presents a case study in simulating leachate generation and transport at a 2000 ton-day landfill facility and assesses leachate migration away from the landfill in order to control associated environmental ...
  • Harajli M.H.; Hamad B.S.; Rteil A.A. (FARMINGTON HILLS38800 INTERNATIONAL WAY, COUNTRY CLUB DRIVE, PO BOX 9094, FARMINGTON HILLS, MI 48333-9094 USA, 2004)
