Structural Behavior of Concrete CEP Forensic

2014-4-1  In order to assess the importance of cracks, structural engineers must analyze the structural behaviour of the concrete elements. These can be stressed mainly in 4 ways: compression, tension, flexure and shear. This bulletin will discuss these types of stress, as well as some basic principles for troubleshooting.

Structural Behavior Evaluation of Reinforced Concrete ...

Reinforced concrete (RC) structures age with time, which results in performance degradation and cracks. These performance degradations do not recover easily, but a performance higher than the existing structures can be expected through reinforcement. There are various reinforcement methods for RC structures. This study selected four reinforcement methods: near-surface mounting (NSM), external ...

2018-8-17  Concrete cover varies for different exposures of the concrete member and for the conditions in which the concrete member is formed. For example, greater cover is required for greater exposure conditions, such as where the concrete element is cast against and permanently exposed to the ground, vs. being formed and located in an interior environment.
