Mechanical and durability properties of ultra-high performance steel FRC made with discarded materials
( Elsevier , 2021 , Article)This study investigates the mechanical and durability properties of 12 ultra-high performance fiber reinforced concrete (UHPFRC) mixes manufactured using alternate aggregate sources. Natural gabbro aggregates (GA), steel ... -
Parametric study on moment redistribution of fiber reinforced concrete continuous beams with basalt FRP bars
( Qatar University Press , 2021 , Poster)The state of Qatar bears harsh environment and coastal conditions which stand for most of the year. As a result, steel-reinforced concrete structures are subjected to rapid corrosion and deterioration. Therefore, there is ... -
Demonstrating the Worth of Recycled Aggregates - A Case Study from Qatar
( American Society of Civil Engineers (ASCE) , 2016 , Conference Paper)Recycled aggregates are widely used in unbound applications in many countries. However, in some areas the materials available may not meet all the requirements of the local specifications. This is the case in Qatar, where ... -
Dynamic Testing of a Laboratory Stadium Structure

Recent issues on stadium monitoring and serviceability: A review
( Springer New York LLC , 2016 , Book chapter)Unlike most of civil engineering structures whose static and dynamic responses are estimated accurately through several codes and guidance, stadiums reserve a distinctive place especially when it comes to their dynamic ... -
Quantification of structural damage with self-organizing maps
( Springer New York LLC , 2016 , Conference Paper)One of the main tasks in structural health monitoring process is to create reliable algorithms that are capable of translating the measured response into meaningful information reflecting the actual condition of the monitored ... -
Causes of construction change orders in Qatar: Contractors' perspective
( Inderscience Publishers , 2016 , Article)The construction industry involves complex processes which are prone to various changes and variations. However, it may be argued that the application of change orders within construction projects in the State of Qatar has ... -
Microencapsulation of calcium nitrate for concrete applications
( National Research Council , 2016 , Article)The use of encapsulating healing agents that allow the self-healing of concrete has emerged as a potential solution to the current decay and costly maintenance of concrete infrastructure; however, many healing agents are ... -
Effect of self-healing calcium nitrate microcapsules on concrete properties
( National Research Council , 2016 , Article)Self-healing concrete with microencapsulated calcium nitrate was investigated. The compressive strength of concrete admixed with microcapsules (as a percentage of the weight of the cement) was tested and compared with that ... -
Performance of corrosion-aged Reinforced Concrete (RC) beams rehabilitated with Fabric-Reinforced Cementitious Matrix (FRCM)
( International Committee of the SCMT conferences , 2016 , Conference Paper)This paper reports on the feasibility of using fabric-reinforced cementitious matrix (FRCM) systems to rehabilitate corrosion-damaged reinforced concrete (RC) beams. Seven large-scale RC beams were constructed and tested ... -
