Behavior Evaluation of Ultrahigh-Performance Concrete Beam Containing Para-Aramid Fibers

open access: yesAdvances in Civil Engineering, 2019
This experimental research was performed to evaluate the shear and flexural behavior for two cases of reinforced concrete beams: ultrahigh-performance concrete (UHPC) and normal-strength concrete jacketed with UHPC.

SEISMIC STRENGTHENING OF EXISTING RC BUILDINGS STRUCTURES USING CONCRETE JACKETING AND FRP MATERIALS

open access: yese-GFOS, 2019
The need for repairing and strengthening RC buildings and their structural elements occurs when their elements do not possess sufficient strength, stiffness, and/or ductility due to damage mostly caused by earthquakes.

Composite concrete columns of 3DP concrete and self-compacting concrete subjected to normal force [PDF]

open access: yes
Conventional concrete columns are cast in forms made of steel or wood. The work of erecting and dismantling the formwork is time-consuming and laborious. Steel forms can be used several times but wood forms are usually only used once or a small number of

Experimental Investigation on Axial Strength Improvement of Cold-Formed Steel Jacketed Concrete Stub Columns

open access: yesInternational Journal of Concrete Structures and Materials
This paper presents an experimental study on the behavior of low-strength concrete columns confined with cold-formed steel under axial compression. The laboratory test specimens consist of four groups of rectangular concrete stub columns in the size of ...

Numerical analysis of strengthening concrete columns by high performance fibre concrete

open access: yesMATEC Web of Conferences, 2018
Concrete is a material that has advantages and disadvantages. High strength in pressure, as well as increased mechanical resistance are its advantages, on the other side, it has a lower tensile strength as its disadvantage.
