Effect of Externally Bonded Strips of Polymer Fiber (frp) on the Shear Strength of R.C Beam [PDF]
Kirkuk Journal of Science, 2010 This research includes the findings of a workable study investigation for topic of externally strengthening by polymer fiber strips (FRP) of shear span and its impact on the behavior of reinforced concrete beams. The study was carried out by casting (18)

Journal of Civil Engineering and Management, 2017 When multi-span RC elements are exposed to fire one usually observes a yielding of span cross-sections while a safety reserve of support cross-sections is still significant. Due to this phenomenon a redistribution of bending moments occurs and the values

EFFECT OF PRESTRESSING STRANDS ON THE LOAD DEFLECTION BEHAVIOR OF STEEL BEAMS [PDF]
Journal of Engineering and Sustainable Development, 2019 Seven simply supported steel beams were tested to explain the effect of strengthening by external prestressing strands. All of these beams have the same steel section, clear span length and the strengthening samples implemented by two external ...

Effect of using different configurations of NSM-CFRP strips on the flexural strength of RC beams [PDF]
MATEC Web of ConferencesThe main objective of this research is to study, experimentally, the flexural strength of lightweight reinforced concrete (LWRC) beams strengthened using the near-surface mounted carbon fiber reinforced polymer technique (NSM-CFRP). Four simply supported

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

REINFORCED CONCRETE TWO-SPAN CONTINUOUS DEEP BEAMS. [PDF]
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 1998 This paper describes the structural behaviour of two equal span continuous reinforced concrete deep beams with clear shear span/depth of web ratios less than 1.3 and loaded symmetrically from the top. The main mode of failure of such beams is characterized by the formation of two symmetrical inclined cracks emanating from the edges of the central ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
