Abstract
Recently, the use of fiber reinforced polymers (FRP) composite material
in construction has grown to solve traditional problems, such as corrosion of steel. FRP bar reinforcement embedded in concrete will result in longer service-life of concrete members. The non-corrosive, high strength, and light weight of the FRP bars would be beneficial to concrete structures in aggressive environment such as bridges, parking structure ... etc. The linear characteristics of FRP up to failure and their relatively low elastic modulus (EFRP = 1/4 Es), raise many questions and concerns regarding their use as reinforcement for flexural members.
TIlls thesis describes the non-linear behavior of interior slab-column
connection reinforced with FRP bars, under mono tonically increasing vertical
loads. Three dimensional non-linear finite element (FE) analysis program
(ANSYS V13) [5] is used. A full scale interior slab column connection
measuring 2500 x 2500 mm, simply supported over its perimeter line located at 250 mm from edges. Two types of FRP bars were used, namely glass fib er
reinforced polymers (GFRP) and carbon fib er reinforced polymers (CFRP).
The behavior is studied in comparison to reference models reinforced with
conventional steel bars.
A total of 35 interior slab-column connection models were constructed
and analyzed up to failure. The studied parameters were; i) tension
reinforcement type (GFRP, CFRP and steel) and reinforcement ratios (0.48 to
1.74%); ii) compression reinforcement GFRP ratios (0.16 to 0.41%); iii)
concrete compressive strength (28 to 60 MPa); iv) column size to slab depth
ratio, (c/d), and v) slab depth (150 to 350 mm).
