Seismic Bahavior Of Reinforced Concrete Liquid Storage Tanks, Iman Shawky Abdel-Rahman
Archived Theses and Dissertations
This thesis presents a study of the effects of seismic loading on reinforced concrete liquid storage tanks. Stresses and displacements were computed by the finite element method to ascertain that they remain within an acceptable safety range when the tank is subjected to earthquake ground accelerations of varying intensities. In the analysis different parameters were considered. This included tank radius, liquid height, and shell thickness, loading conditions resulting from both hydrostatic and hydrodynamic pressures, and a variety of boundary conditions at the top and bottom of the tank, including a cover dome. The finite element package (ABAQUS) was used to …

Assessment Of Chloride Ingress Into Concrete, Mohamed Tamer Farouk Bassuoni
Archived Theses and Dissertations
The corrosion of steel reinforcement has been a prime concern for concrete users. Chloride ingress into the concrete matrix disturbs the passive layers in the vicinity of steel, which results in corrosion initiation. Cementitious materials were successfully implemented in concrete mixtures to enhance their properties and minimize chloride permeability into concrete. Although numerous tests and techniques have been developed over the past years, reliable assessment of chlorides remains a challenging task. Th.is study aims at enhancing the understanding of techniques used for the assessment of chloride ingress and investigating potential correlation between these techniques. The study comprised eighteen mixtures made …
