Durability of preflex beam under cyclic loading
Engineering Science and Technology, an International Journal, 2021 Preflex beam girders with remarkable advantages are widely used in bridge structures. With aging, preflex beam bridges undergo concrete cracking and degrade as the cracks propagate and deteriorate due to repeated service load application and exposure to ...

Shear strengthening of concrete T-beams with lateral layers of UHPC [PDF]
MATEC Web of Conferences, 2022 Concrete T-beams are commonly used in building slab systems and bridge decks. They may require strengthening in shear when they are deteriorated or when loading requirements increased. This research project studied the shear behaviour of concrete T-beams

CFRP strengthened continuous concrete beams [PDF]
Structures <html_ent glyph="@amp;" ascii="&"/> Buildings, 2003 This paper reports the testing of five reinforced concrete continuous beams strengthened in flexure with externally bonded carbon-fibre-reinforced polymer (CFRP) laminates. All beams had the same geometrical dimensions and internal steel reinforcement. The main parameters studied were the position and form of the CFRP laminates.

Design And Tests Of Prestressed Concrete Beams [PDF]
Fire Safety Science, 1997 A prestressed TT beam had been designed considering the ultimate limit state of bending, and considering a temperature distribution given by a graph which was valid for a section with a similar shape. When tested in a furnace, it proved to have a fire resistance of only 79 minutes instead of the 2 hours foreseen by the calculation. An investigation was

Effect of maximum grain size on value of modulus of rupture reactive powder concrete
Media Komunikasi Teknik Sipil, 2020 Modulus of rupture (R) is a measurement of a tensile strengh of a concrete beam. The value of R is affected by the size of fine aggregat grain, the density of the concrete beam and the water-cement ratio.

Prestress Loss Distributions along Simply Supported Pretensioned Concrete Beams
Electronic Journal of Structural Engineering, 2016 The prestressing forces in prestressed tendons undergo a process of reduction over a period of time. A common assumption is that prestress loss is constantly distributed throughout the span of a simply supported pretensioned concrete beam.

Reinforced concrete beams with lightweight concrete infill
Scientific Research and Essays, 2012 In structural design, an ideal situation in material saving is to reduce the weight of the structure without having to compromise on its strength and serviceability. A new lightweight sandwich reinforced concrete section has been developed with a novel use of lightweight concrete as infill material. The section, namely LSRC section, is suitable for use
