    • Cost optimization of composite beams using genetic algorithms 

      Senouci, Ahmed B.; Al-Ansari, Mohammed S. ( Elsevier Ltd , 2009 , Article)
      This paper presents a genetic algorithm model for the cost optimization of composite beams based on the load and resistance factor design (LRFD) specifications of the AISC. The model formulation includes the cost of concrete, ...

    • Drift optimization of high-rise buildings in earthquake zones 

      Al-Ansari, Mohammed; Senouci, Ahmed ( John Wiley & Sons, Ltd. , 2011 , Article)
      This paper presents a Drift Design Structural Model (DDSM) for the design optimization of high-rise buildings in seismic zones. The model is formulated as a Generalized Single Degree of Freedom System subjected to equivalent ...

    • Paraboloid Shell As Footing 

      Al Ansari, Mohammed S. ( Qatar University , 1999 , Article)
      A simplified method for the design of paraboloid shell footing base on the displacement of the shell's crown where the column axial load is transferred to the footing has been developed. A case study was presented to ...

    • Performance of modified self-healing concrete with calcium nitrate microencapsulation 

      Al-Ansari, Mohammed; Abu-Taqa, Ala G.; Hassan, Marwa M.; Senouci, Ahmed; Milla, Jose ( Elsevier Ltd , 2017 , Article)
      This study investigates the strength reduction associated with incorporating calcium nitrate microcapsules in concrete. It also proposes modifications to the calcium nitrate micro encapsulation procedure to minimize the ...

    • Proposed formulas for estimating splitting tensile, shear and flexural strengths, and long term deflection assessment of self-compacting concrete elements 

      Al-Ansari, Mohammed S.; Abu Taqa, Ala G.; Senouci, Ahmed B.; Eldin, Neil N.; Helal, Mohamed; ... more authors ( American Scientific Publishers , 2017 , Article)
      This paper investigated the splitting tensile and shear strengths and the modulus of rupture of Self Compacting Concrete (SCC) elements with fly ash, micro silica and polycarboxylate ether superplasticizer for various ...

    • Simplified Method For Plate Deflection Calculation 

      Al Ansari, Mohammed S. ( Qatar University , 1997 , Article)
      This paper presents a simplified method for the calculation of thin-plate deflections. The method, which deals with uniformly loaded plates, uses the stiffness method to obtain plate deflection equations for specified ...

    • Structure Mixture Response Of Buildings Due To Simulated Earthquake Loading 

      Al Ansari, Mohammed S.; Senouci, Ahmed B. ( Qatar University , 2002 , Article)
      This paper presents two case studies to evaluate the performance of the structure mixture theory in the earthquake response analysis of buildings. In the first case study, the actual earthquake responses of the two-story ...
