In this research, the size effect on shear strength of concrete beams without coarse
aggregate has been studied by evaluating the ACI 318-14, ACI 318-19, and Eurocode 2 …

Failures in building structures due to the earthquake occurred more frequently in columns
than in beams, mainly when they have not been designed to comply with the strong column …

Displacement and curvature ductilities are the key parameters in the design of structural
columns because columns are very important structural members for the strength and …

This study examines the behavior of circular concretes externally confined by green
sustainable WHBR FRP containing water hyacinth fiber ropes and bio-resin. This study …

Several structural failures occur in the columndue to the lack of confinement. The circular
column is not popular for regular buildings. The use of circular spiral is only familiar tothe …

The accuracy of designing the performance of concrete structures nowadays not only
depends on the use of standard materials (cement, sand, and gravel) for certain concrete …

This paper examines the possible influence of external confinement on concrete by utilizing
traditional steel bars. The test specimens were concrete cubes of 150 mm in size. Steel bars …

Natural disasters can cause the collapse of buildings, either the super-or substructures of
the building. In addition to columns, beams that function as supports to floor slabs are also …

Concrete structures close to seawater cannot be avoided in the construction of current
facilities and infrastructure. Concrete submerged in seawater will reduce its strength and …

RC Structures with poorly confined columns have been known to have poor performance
during earthquake events. Brittle failures of columns with low ductility can lead to …
