Tests of deep concrete beams with internal fiber-reinforced polymer (FRP) reinforcement have shown that such members can exhibit lower shear strength than members with conventional steel reinforcement. To model this effect, the current paper proposes an approach based on a two-parameter kinematic theory (2PKT) for conventional deep beams. The 2PKT is built on a kinematic model with two degrees ...

An explicit expression of natural frequencies through crack parameters is derived for multiple cracked beams with simply supported boundaries using the Rayleigh quotient. The obtained provides not only a simple tool calculating beams, but also allows employing so-called scanning method detecting cracks in from measured frequencies. A numerical example demonstrates that method, combination quoti...

In this paper a procedure for the static identification and reconstruction of concentrated damage distribution in beam-like structures, implemented in a dedicated software, is presented. The proposed damage identification strategy relies on the solution of an optimisation problem, by means of a genetic algorithm, which exploits the closed form solution based on the distribution theory of multi-...

This study investigates the behavior of three concrete beams reinforced with steel and GFRP bars under fire exposure. The tests were conducted including one control steel-reinforced (RC) beam two GFRP-RC beams. exposed to according standard curve ISO 834 for 3 h. investigation parameters included reinforcement types (i.e., bars) diameter bars. Based on experimental results, during exposure, def...

--The Motor Current Signature Analysis (MCSA) is considered the most popular fault detection method now a day because it can easily detect the common machine fault such as turn to turn short ckt, cracked /broken rotor bars, bearing deterioration etc. The present paper discusses the fundamentals of Motor Current Signature Analysis (MCSA) plus condition monitoring of the induction motor using MCS...

Abstract At present, the need to make use of industrial waste materials is increasing due their harmful effects on environment. In present work, behavior hybrid reinforced T-Beam with partial substitution recycled rubberized concrete studied. The finite element modeling by using ANSYS version 15 program. It contains also all required steps needed create models that were prepared study beams (RR...
