The application of fiber-reinforced polymer bars is rapidly rising in concrete structures because corrosion resistance and high tensile strength. By contrast, reinforced with FRP illustrate less ductility brittle failure without warning than conventional steel bars. Hybrid the combination can simultaneously increase strength ductility. This paper aims to estimate effective moment inertia hybrid...

Overproduction of nitric oxide (NO) by inducible NO synthase contributes toward refractory hypotension, impaired microvascular perfusion, and end-organ damage in septic shock patients. Tetrahydrobiopterin (BH4) is an essential NOS cofactor. GTP cyclohydrolase 1 (GCH1) is the rate-limiting enzyme for BH4 biosynthesis. Under inflammatory conditions, GCH1 activity and hence BH4 levels are increase...

Reinforced concrete (RC) structures may be subjected to an increase in load, severe environmental attack, and other factors that lead deterioration. Strengthening/repair techniques are typically used upgrade the strength or enhance durability, which extends service life of structures. In current study, behavior reinforced beam strengthening by UHPC layer with/without construction joints were in...

Glass fiber-reinforced polymer (GFRP) reinforcements are useful alternatives to traditional steel bars in concrete structures, particularly vertical structural elements such as columns, they less prone corrosion, and impart increasing strength endurance of buildings. There is limited research on the finite element analysis (FEA) behavior hollow glass reinforced (GFRPRC) columns. The portion can...
