This research aims to improve the structural safety of wide floor slabs with openings due to embedded non-structural elements. The multidisciplinary design of these slabs has resulted in various safety issues, including errors in the design due to the absence of a calculation method and insufficient integration between designs of different...

Strain Hardening Cementitious Composite (SHCC) is an innovative type of fibre-reinforced cement-based composite that has superior tensile properties. Because of this, it holds the potential to enhance the shear capacity of reinforced concrete (RC) beams, if applied properly.<br/><br/>Experimental research was thus carried out with the purpose of...

To calculate the flexural-shear resistance of prestressed concrete members without shear reinforcement, a method based on Critical Shear Crack Theory (CSCT) has been presented for the new Eurocode (prEN1992). Two alternatives provided in draft 7/2020 (prEN1, prEN2) are the starting point given, and two other alternatives are proposed for...

The outstanding mechanical properties of ultra-high-performance fiber-reinforced concrete (UHPFRC) can be used to improve the punching behavior of new slab-column connections. This study investigates the punching capacity of flat slab-column connections built with a rational combination of normal strength concrete (NSC) and UHPFRC in critical...

For calculation of the resistance of a composite slab against the transverse shear force, the Eurocode 4 (composite structures) simply refers to the calculation procedures of the Eurocode 2 (concrete structures). It is assumed that the composite slab consists out of a consecutive range of concrete ribs in its width direction, which are solely...

According to the current codes and guidelines, shear assessment of existing reinforced concrete slab bridges sometimes leads to the conclusion that the bridge under consideration has insufficient shear capacity. The calculated shear capacity, however, does not consider the transverse redistribution capacity of slabs, and thus leads to overly...

The design of FRP profile-concrete composite sections, including beams and decks, is usually governed by the shear strength of the FRP profiles. However, analytical methods that can precisely predict the shear capacity of the composite sections have not been well developed, because there is lack of knowledge of the FRP-concrete composite...

Due to the alteration in height, the centroidal axis of a non-prismatic beam has a non-linear layout when compared to a prismatic beam. Therefore, in case of a non-prismatic beam, the vertical cross-section cut, on which analysis from the codes are performed, is no longer perpendicular to the centroidal axis, unlike prismatic beam. Moreover, due...

Circular Economy refers to a move from linear business models, in which products are manufactured from raw materials, used and then discarded, to circular business models where products or parts are re-used, remanufactured or recycled. Structural steel is highly compatible with this concept; however, when steel-concrete composite structures are...

The deconstruction of steel-concrete composite structures in buildings and the later separation of the materials is a labour- and cost intensive work. The shear studs are welded on the steel beam and imbedded in the concrete deck and a large amount of cutting work becomes necessary. As a result, recycling is difficult and the potential for...

Composite girder with corrugated steel web is one of the promising concrete-steel hybrid structures with superior properties and cost effectiveness widely applied in highway and railway bridges. The connection between concrete slabs and corrugated steel web is an important part of such composite structure. In order to improve pouring quality...

Digital Image Correlation analysis is performed to obtain measurements of the crack kinematics of four reinforced concrete beams without shear reinforcement. The results are used to implement the critical shear displacement theory. This new theory proposes that the opening of the critical inclined crack can be considered as a lower bound for the...

A fully triaxial material model for concrete was implemented in a commercial finite element code. The only required input parameter was the cylinder compressive strength. The material model was suitable for non-linear finite element analyses of large concrete structures. The importance of including a crack closure algorithm was demonstrated on a...

This paper presents an experimental research program aiming at assessing the current code provisions of vmin. A large test series was carried out, by varying the reinforcement ratio and loading conditions, the minimum average shear stress that can cause shear failure of a specimen with different depth, concrete strength is determined. The three...

Assessment of the capacity of the existing infrastructures has become more relevant in the recent years. With regard to the concrete bridges, the shear capacity of a large amount of existing concrete slab bridges reinforced with plain (smooth) bars are of concern. However, it was argued that the shear formula that is currently adapted in the...

In the Netherlands, the shear capacity of a large number of existing reinforced concrete solid slab bridges is subject to discussion, as initial assessments indicated that their capacity was insufficient. In certain cases, the deterministic value of the moment capacity is larger than the deterministic value of the shear capacity. However, when...

A large number of existing reinforced concrete solid slab bridges in the Netherlands are found to be insufficient for shear upon assessment. However, research has shown additional sources of capacity in slab bridges, increasing their total capacity. Previous testing was limited to half-scale slab specimens cast in the laboratory. To study the...

The application of prefabricated and usually prestressed concrete elements has increased since mid-20th century. These elements are at the point of reaching the end of their life span, are subjected to damages or a change in functionality. Therefore, it is necessary to evaluate their structural safety. In many cases, existing structures do not...

An unpublished study by Prof. A.W. Beeby shows the differences in strength capacity between a reinforced concrete beam without shear reinforcement and the same beam with a cut-out section at the middle of the span. The cut-out section exists at the bottom part of the beam while the reinforcement still remains. It remarkably turns out that the...
