This article proposes a new constitutive model for the cyclic behavior of rubberized concrete confined with fiber-reinforced polymer (FRP) sheets. The is calibrated experimental results from 18 (CRuC) cylinders tested in compression. had 60% total aggregate volume replacement recycled tyre rubber. Parameters investigated include type confining material (Carbon or Aramid FRP) and number layers (...

This paper conducts an experimental study on the axial compressive performance of FRP-steel-concrete composite columns. Nine short columns were produced and evaluated in study, comprising three concrete-filled steel tube reference six columns, respectively denoted as “reference columns” “composite columns”. Two categories failure modes, including shear waist drum, observed from experiments. The...

Torsional demand acting on beams can significantly effect structural behavior and cause high-local stresses. The torsional resistance of be potentially increased by using fiber-reinforced polymer (FRP) sheets. In this study, basalt (BFRP) carbon (CFRP) fabrics with different layouts are used to strength the steel I-beams, enhancement in is investigated experimentally numerically. First, 12 spec...

Fiber reinforced polymer (FRP) has been used in the construction industry because of its advantages such as high strength, light weight, corrosion resistance, low density and elasticity. This paper presents a review bonding techniques adopted to strengthen timber beams using FRP achieve larger spans. Different methods between have summarized with focus on influencing factors their effects well ...

Due to inadequacies of reinforcement design in older structures and changes building codes, but also the change use existing structures, reinforced concrete (RC) beams often require upgrading during renovation. The combined shear flexural strengthening with composite materials, fibre-reinforced polymer sheets (FRP) textile mortars (TRM), is assessed this study. An experimental campaign on twelv...

Magnesium phosphate cement (MPC) has been proven to be a very good repair material for deteriorated concrete structures. It has excellent adhesion performance, leading to high bonding strength with old concrete substrates. This paper presents an experimental study into the properties of MPC binder as the matrix of carbon fiber sheets to form fiber-reinforced inorganic polymer (FRIP) composites....

introduction: the information recorded in medical sheets can help us facilitate the treatment process, recognize the quality of performance of the medical staff, plan health care programs and make accurate and appropriate decisions. this study intends to compare the quality of recording information in admission and summary sheets of three hospitals in isfahan in the first six months of 1381. ma...
