Buckling Behavior of Semi-scale Steel Tank with Carbon Fiber Reinforced Polymer Ring Subjected to Lateral Uniform Pressure Loading
Research on increasing the buckling strength of tanks carrying fluid and also cylindrical shells of thin-walled steel in civil engineering and mechanics is important. This is due to the widespread use of these structures in the industry. Due to the low thickness of the body and also due to the pressure forces entering these tanks, these structures are exposed to lateral buckling. In this resear...
متن کاملBehavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets
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...
متن کاملContract number : FA 2386 - 09 - 1 - 4038 Research title : Damage detection of laminated CFRP structures using electric pulse wave transmission
Carbon Fiber Reinforced Polymer (CFRP) laminates are applied to many aerospace structures. For these laminated CFRP structures, it is quite difficult to detect internal damage such as delamination, matrix cracks, and local fiber breakages. Carbon fibers are adopted as reinforcement in CFRP and it is an excellent electric conductor at the same time. The carbon fiber has been used as a strain sen...
متن کاملPredicting the Long Term Life of Polymer Composites Using Time Temperature Shift Factor (TTSF)
The use of Carbon Fiber–Reinforced Polymers (CFRP) has increased in number of industries i.e. aerospace, automobiles, marine, medical and sports due to their light weight and high strength-stiffness. However, their properties are greatly affected under extreme e environmental conditions i.e. high temperatures and moisture uptake. The paper reports an experimental study to determine the response...
متن کاملThe optimum configuration of FRP laminates of coupling shear wall concerning the load capacity
Using of CFRP carbon sheets because of their high strength, lightness and ease of use have been very expanded in retrofitting concrete members. Including shear walls systems FRP can be used in order to rebuild or maintain the strength of an aged structural member. Repairing, or retrofitting of the intact structural member is conducted to enhance the structural resistance that was deteriorated d...
