The Adomian decomposition method (ADM) and high-pass filters are employed in this study to investigate the free vibrations and damage detection of cracked Euler-Bernoulli beams. Based on the ADM and employing some simple mathematical operations, the closed-form series solution of the mode shapes can be determined for beams consisting of an arbitrary number of cracks under general boundary condi...

Reinforced concrete (RC) structures require strengthening for numerous factors, such as increased load, modification of the structural systems, structural upgrade or errors in the design and construction stages. The side near-surface mounted (SNSM) strengthening technique with glass fiber-reinforced polymer (GFRP) bars is a relatively new emerging technique for enhancing the flexural capacities...

This paper reports an experimental study on the behavior and shear strength of concrete beams reinforced with longitudinal GFRP bars mixed sea water. In order to evaluate how much contributes resistance, seven were tested in bending. Similar size strength, longitudinally glass fiber-reinforced polymer bars; however, they did not even have reinforcement. The beams, which measured 3,100 mm length...

Fibre Reinforced Polymer (FRP) bars are effective alternatives to steel bars. This paper performs the shear evaluation of geopolymer concrete beams reinforced with Glass (G) / Basalt (B) FRP Glass/ stirrups. Totally nine GFRP/BFRP/Steel size 100 × 160 1700 mm were cast in geopolymer/conventional and tested by varying ratio span an depth such as 3.6, 3.9, 4.3 a four-point static bending test. Th...

The durability of precast structures often depends on quality execution the connections between structural elements. Essential also is their design and proper exploitation. This paper focuses magnitude damages as well repair methods used for a slab, which consists prestressed double T slab elements supported inverted girders. It was found that during execution, girders were forced to fit dowel ...
