Effect of flexural crack on plain concrete beam failure mechanism A numerical simulation [PDF]
Fracture and Structural Integrity, 2016 The flexural failure of plain concrete beam occurs along with development of flexural crack on beam. In this paper by using ABAQUS, mechanism failure of plain concrete beam under three steps have been simulated.

Study on failure mechanism of reinforced concrete beam based on cohesive zone model
Xibei Gongye Daxue Xuebao, 2022 The problem of crack propagation in reinforced concrete beams is common in practical engineering. It is very important to correctly describe the law of crack propagation, the mechanism of fracture failure and the internal stress and deformation ...

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 ...

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.
