The strain-hardening behaviour of cementitious composites is the result of a synergistic behaviour of the cement matrix and fibres in a cracked cross-section. The distribution and orientation of the fibres are essential in order to obtain such favourable tensile behaviour. Strain-hardening composites can be applied and are especially useftil in...

As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse existing bridges are bemg studied. Proof loading of bridges is an option to study the capacity when crucial information about the structure is lacking. This information could be related to the material (for example, the effect of alkali-silica reaction on the...

Proof loading has been considered as an effective approach in the assessment of existing concrete bridges. This paper presents a study of acoustic emission measurement in a proof loading of an ASR affected concrete slab bridge (Zijlweg bridge). Because of the uncertainty on the mechanical properties of the ASR affected concrete. The attenuation...

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...

This paper presents the Acoustic Emission (AE) measurement of several tests carried out on reinforced concrete beams sawn from a 50 years old concrete bridge – Ruytenschildt bridge. The purpose of these tests is to provide additional information to the already executed in-situ load testing on the bridge. In addition to the AE measurement...

Proof load testing can be a suitable method to show that a bridge can carry the required loads from the code without distress. This paper addresses the preparation, execution, and analysis of a proof load test on a four-span reinforced concrete solid slab bridge, viaduct de Beek. The bridge has one lane in each direction, but was restricted to a...

As the existing bridge stock is aging, improved assessment methods such as proof load testing become increasingly important. Proof load testing involves large loads, and as such the risk for the structure and personnel can be significant. To capture the structural response, extensive measurements are applied to proof load tests. Stop criteria,...
