Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]
, 1988 A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in ...

Multicriteria decision-making method applied to optimized reinforced concrete, steel, and wood beams
Exacta, 2022 Optimization techniques have been increasingly used to obtain structures of lower cost or weight. However, the result obtained depends on the choice of materials. This can be based on factors such as cost, performance, and environmental impacts, as well

Induced shear in reinforced concrete beams with synthetic aggregate
Revista IBRACON de Estruturas e Materiais, 2023 The increasing aluminum production demands larger volumes of bauxite residue (BR) to be stored in the Amazon region. There are millions of tons of waste without reuse but with high potential for use in civil construction as artifacts or components for ...

The coherent beam-beam interaction [PDF]
Conference Record of the 1991 IEEE Particle Accelerator Conference, 2002 The authors present the results of a new beam-beam simulation program that allows for a self-consistent calculation of the electromagnetic fields of the beams by treating general (non-Gaussian) beam distributions. The simulation program calculates the fields from the coordinates of the test-particles, and does not impose any restrictions on the beam ...

Optimization of Concrete Beams Reinforced with GFRP Bars [PDF]
Journal of Soft Computing in Civil Engineering, 2022 Members with GFRP bars exhibit different behavior from those with steel bars due to the brittle and low elastic modulus of the GFRP bars. However, there are limited studies considering the optimum design of reinforced concrete members with GFRP bars ...

To beam or not to beam: that is the question [PDF]
Dentomaxillofacial Radiology, 2013 After reading the articles by Lione et al,1,2 I was very upset and concerned about the way the authors intentionally misused ionizing radiation to assess the effectiveness of an orthodontic treatment. Both studies were published at a similar time and cover the same unfortunate 17 pre-pubertal children, who had a mean age of only 11.2 years (range 8–14 ...
