In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...

a large number of bridges and buildings that are currently used, are made of slabs with opening. some of these buildings and bridges have been severely damaged because of natural disasters such as earthquake, storm and other effects such as materials fatigue and alkaline and corrosive agents. therefore, retrofitting and strengthening of these structures is essential and affordable. in this rese...

The need to reduce carbon emissions has recently become prevalent in light of concerns related climate change. Since the cement industry causes approximately 8% global CO2 emissions, it might be an urgent necessity include replacement materials within concrete industry. An important question arises about if such negatively affects cyclic or seismic behavior reinforced (RC) elements. This resear...
