Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: This study is mainly concerned with evaluating the performance of several types of reinforced concrete barrier walls subjected to blast loads. Parametric studies are carried out for nine RC barrier wall systems modeled in the three dimensions with different geometries, configurations, and variable parameters. ANSYS AUTODYN software version 18.2 is used to model and analyze these systems using three-dimensional explicit dynamics finite element analysis. The nine systems are studied under several parameters, such as explosive charge weight and stand-off distance from the explosion source to the wall. Their effect on the wall damage and its deformations and effective strains, the pressure-induced at different locations, and the generated energy are analyzed. One hundred and forty-four reinforced concrete barrier wall models are studied to achieve this thesis goal. Comparisons between the results show the difference between some values and the indifference of others{u2019} values and parameters

This study is mainly concerned with evaluating the performance of several types of reinforced concrete barrier walls subjected to blast loads. Parametric studies are carried out for nine RC barrier wall systems modeled in the three dimensions with different geometries, configurations, and variable parameters. ANSYS AUTODYN software version 18.2 is used to model and analyze these systems using three-dimensional explicit dynamics finite element analysis. The nine systems are studied under several parameters, such as explosive charge weight and stand-off distance from the explosion source to the wall. Their effect on the wall damage and its deformations and effective strains, the pressure-induced at different locations, and the generated energy are analyzed. One hundred and forty-four reinforced concrete barrier wall models are studied to achieve this thesis goal. Comparisons between the results show the difference between some values and the indifference of others{u2019} values and parameters
