Engineered Cementitious Composites for Enhanced Seismic Resistance of Interior Beam-column Connections

Engineered cementitious composite (ECC) is an ultra ductile cement-based material reinforced with fibers. It is characterized by high tensile ductility and tight crack width control. Thanks to the excellent performance, ECC is emerging in broad applications to enhance the loading capacity and the durability of structures. However, ECC also faces a limitation on dimensional stability

Numerical Dynamic Simulations for the Prediction of Damage and Loss of Capacity of RC Column Subjected to Contact Detonations

The assessment of dynamic response and residual capacity of reinforced concrete (RC) columns to blast load is decisive for protection of buildings, especially regarding progressive collapse risk. In the case of explosive devices placed next to a critical structural element, complex and extreme loading is applied on the nearby system and the material response is

Failure Mode Scaling Transitions in RC Beams in Flexure: Tensile, Shearing, Crushing

Reinforced concrete beams in flexure exhibit three different collapse mechanisms by varying the mechanical and geometrical parameters. The limit cases are: tensile failure for low steel percentages and/or small and slender beams, and crushing failure for high steel percentages and/or large and stocky beams. The intermediate collapse mechanism, and, therefore, the most frequent, is represented

Fiber Orientation in Ultra High Performance Fiber Reinforced Concrete and its Visualization

With the aim of investigating fiber orientation in ultra high performance fiber reinforced concrete (UHPFRC), a transparent model concrete containing fibers was placed in beam molds to visualize fiber orientation during placing. As a result, fibers were found to be obliquely oriented upward when the pouring position of concrete was fixed near one end of

Numerical Modelling of Large Reinforced Concrete Specimens based on Experimental Tests from Benchmark Concrack

Most infrastructures are reinforced concrete (RC) structures. In order to deal with the security and durability of RC structures, the stackholders have to survey the noticeable signs of degradation resulting from interactions between the environment and the constitutive materials. As the matter of fact, these interactions can reveal cracks, which are major with respect to

Shear Strength of ASR-Deteriorated RC Members and Shear Reinforcing Effect of Repair by Adding Rebar

This study aims at clarifying the effects of rebar rapture caused by ASR on the mechanical performance of RC members. Rapture of tensile or shear reinforcement was simulated in RC beam specimens, which were subjected to a bending test after deteriorated by ASR. Some of the beams were repaired by adding rebars, and the effects

The Effect of Concrete Strength on Cracking of SFRC Members

Tension stiffening is still a matter of discussion into the scientific community. The study of this phenomenon is also relevant in structural members made of fibre reinforced concrete. This paper aims at investigating tension stiffening by presenting tension-test results on reinforced concrete prisms having different sizes, reinforcement ratios, amount of fibres and concrete strength. The

Limit states of RC structures: Reinforcement corrosion, reliability and modelling

Reinforced concrete is a widely used material for structures of different types as bridges, buildings, underground structures and others. Damage due to reinforcement corrosion is recognized as one of the major causes of deterioration of such structures with service life reduction and considerable additional costs as consequence. An extensive amount of research on these topics

Shear Database for Reinforced and Prestressed Beams made with Fiber Reinforced Concrete

A total number of 215 structural elements were used to prepare a complete database to analyze the shear behavior and the influence of each parameter on shear out of 363 elements of the experimental database. 148 elements were eliminated for various reasons. Thus, the following items were removed: those with different failure modes to shear,

Cracking Analysis of Reinforced Concrete Beams using a Finite – Discrete Element Methods Approach

Combining the use of finite element analysis and a discrete element approach, this contribution aims at proposing a new post-treatment technique to help one in computing the cracking openings in complex reinforced concrete structures subject to mechanical loadings.
