Strengthening of concrete beams by CFRP: Experimental study and finite element analysis

open access: yesJournal of Building Materials and Structures, 2014
This work presents an experimental study on the mechanical behavior of structural concrete reinforced by carbon fiber reinforced polymer (CFRP). The main purpose of this study is to test the applicability of this method of reinforcement in the beams to ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

open access: yesStructural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

open access: yesStructural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Rotation capacity of continuous reinforced concrete slab strips revisited

open access: yesStructural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Heat Transfer Characteristics for Practical Hydrogen Pressure Vessels Being Filled at High Pressure

open access: yesJournal of Thermal Science and Technology, 2008
Experiments have been conducted to measure the rise in temperature of hydrogen and vessel wall during filling of commercially available, practical tanks to 35 and 70 MPa. Three test vessels with volumes 205, 130 and 39 liters are investigated.

EBI-strengthening of CFRP

open access: yesJournal of Advanced Science, 2006
Carbon fiber reinforced (CFRPs) are increasingly commonly used composite materials based on carbon faiber. To evaluate the strength was used the tensile test, bending test and Carpy impact Test. We concluded that EB irradiation reinforced mechanical properties for CFPRP.

The challenges of GFRP RC beam design for limit states

open access: yesStructural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.
