Effective nitrogen management is essential for sustainable coffee production and enhanced yield. This study evaluated the effects of five nitrogen application rates (per annum; N1: 120 kg/ha, N2: 240 kg/ha, N3: 360 kg/ha, N4: 480 kg/ha, N5: 600 kg/ha) applied in equally distributed monthly rates over 2 years, from flowering to harvest, on Coffea ...

Anchorage System Contribution to Post‐Tensioned Bridge Collapse
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Role of the modifications at the interface in glass fiber reinforced composites for damage monitoring. ABSTRACT Glass Fiber Reinforced Polymers (GFRPs) are widely used in structural applications but degrade over time due to internal damage. Structural Health Monitoring (SHM) enables early damage detection, improving reliability and reducing maintenance

Determination of residual welding stresses in a steel bridge component by finite element modeling of the incremental hole-drilling method [PDF]
For welded bridge components, the knowledge of residual stresses induced by welding is essential to determine their effect on the fatigue life behavior resulting in optimal fatigue design and a better knowledge about the fatigue strength of these welded ...

Fatigue Life Assessment of Orthotropic Steel Deck with UHPC Pavement
In recent years, a number of large-span bridges with orthotropic steel decks were constructed in China. With increasing traffic volumes and higher wheel loads, many fatigue cracks developed at the welds and the edge of cut-out holes.
