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...

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...
