Construction material subjected to repetitive or cyclic loading have to be qualified for their fatigue behaviour. Generally their behaviour is considered satisfactory if they withstand two million cycle of repetitive loading without distress or failure at that required mean stress level and range stress.

The high cost of conventional building materials is a major factor affecting housing delivery in world. This has necessitated research into alternative materials of construction. The project paper aims at analyzing flexural and compressive strength characteristics of concrete produced using crushed, granular coconut as substitutes for conventional coarse aggregate with partial replacement using M30 grade concrete. Beams are casted, tested and their physical an ....etc

Fatigue Behavior of Reinforced Concrete Beams Strengthened with Different FRP Laminate Configurations
Synopsis: This paper presents testing results of thirteen small-scale beams
strengthened using carbon fiber-reinforced polymer composites tested under repeated
loads to investigate their fatigue behavior. The beams were strengthened using
different thicknesses and widths of composite laminates to identify parameters that
would generate different failure modes. Two predominant fatigue failure modes were
identified through these tes ....etc

ABSTRACT
This paper presents the results of experimental studies concerning the flexural strengthening of RC beams using externally bonded Slurry Infiltrated Mat CONcrete (SIMCON) laminates. A total of four reinforced concrete beams were cast and tested in the laboratory over an effective span of 3000 mm. Three beams were strengthened with bonded SIMCON laminate at the bottom under virgin condition and tested until failure; the remaining one beam was used as control specimen. Static responses of all the beams w ....etc

Deflection of beams
Abstract
The basic aspects of Probe Beam Deflection techniques, used to detectconcentration gradients in electrochemical systems, are described.
The different techniques is first discussed. Then, a critical review of published applications of the techniques to various electrochemical systems is performed. Among the systems whom these techniques has been applied are: electrochromic oxides, conducting polymers, redox polymers, underpotential deposition, surface electrochemical reaction on solid ele ....etc

Reinforced concrete structures often have to face modification and improvement of their performance during their service life. The main contributing factors are change in their use of ,new design standards, deterioration due to corrosion in the steel caused by exposure to an aggressive environment and accident events such as earthquakes .In such circumstances there are two possible solutions: replacement or retrofitting.
Retrofitting of flexural concrete elements are traditionally accomplished by externally bonding steel plates to concrete whi ....etc
