Behavior of Concrete Filled Steel Tube (CFST) Under Different Loading Conditions
Abdalla, Suliman Hassan (2012-06)Concrete Filled Steel Tubes (CFSTs) were used in construction in the early 1900's. However, the research into CFSTs did not begin until the 1960s. From that time onwards, several studies were conducted on the CFSTs to fully ... -
Behavior of FRP-RC Columns Using BFRP Ties under Concentric Loading
Obeidat, Khaled (2019-12)Several studies have investigated the use of Fiber-Reinforced Polymers (FRP) rebars in reinforced concrete (RC) flexural members. However, not enough depth of understanding is currently available with regards to their use ... -
Buckling of Inhomogeneous and Functionally Graded Columns
Aldadah, Mohammed (2014-07)Buckling is an instability encountered in a wide variety of problems, both in engineering and biology. Almost all engineering structures are designed with adequate safety factors to prevent failure due to buckling, yielding, ... -
Buckling of Pretwisted Steel Columns
Megahed, Mai (2015-01)Buckling is a mode of failure that is mainly observed in compression members due to structural instability. Inducing a natural pretwist along the length of a column section makes the column have a different resistance at ... -
Characterization and Modeling of Damage in Steel at Different Strain Rates
Al-Himairee, Reem (2011-01)The structural behavior of steel, as many structural materials, changes during deformation processes under complex mechanical loadings. The damage process may start at some point in the deformation process in the form of ... -
