Abstract: In this paper the results of tests performed on specimens and structural elements made of steel fiber reinforced concrete (SFRC) are presented. Fiber content of the concrete ranged from 0 to 60 kg/m

Abstract: The long-term assessment of large and complex civil infrastructures, such as prestressed concrete bridges, based on finite-element (FE) modeling remains a challenging task. The construction process, the influence of erection ...

Abstract: The use of finite-element packages by practioners as a design tool for reinforced concrete structures has increased considerably in the last few decades. All structural codes of practice recognize the assumption of linear ...

Abstract: Dynamic testing in the condition assessment of existing bridges to support their rehabilitation and strengthening designs is becoming a common procedure, yet additional dynamic testing after rehabilitation is rare. ...

Abstract: One of the main obstacles to a wider use of self-compacting concrete (SCC) is its sensitivity to small variations of the constituent materials, mix proportions, and other external factors. The main objective of this paper ...

Abstract: The knowledge about the cyclic behavior and effects of fatigue on interfaces between concrete cast at different times, subjected to shear stress, is still very limited. This aspect is particularly relevant in structures ...

Abstract: Continuous bridge decks constructed with precast girders undergo significant stress changes caused by the concrete delayed deformations because of creep and shrinkage. These effects must be taken into account in the design ...

Abstract: This paper aims to solve an optimal irrigation water resources allocation problem applied to Alqueva River Basin irrigation system in Portugal. A multiobjective model was developed for this purpose in which the economic, ...

Abstract: In this paper a numerical and an experimental study on reinforced concrete box culverts (BC) behavior is presented. A BC under a
