Axial Load Behaviour of Large Scale Concrete Columns
This research mainly intended to investigated the axial load behavior of
large-scale rectangular columns, the test specimens were geometrically
similar reinforced concrete columns of square cross-section with sides,
D, of 50 mm, 100 mm and 200 mm., the effective lengths corresponding to
the largest cross section were 580, 1080 and 2080 mm, the effective
lengths corresponding to the middle section size were 290, 540 and 1040
mm and the effective lengths corresponding to the smallest cross section
were 145, 270 and 520 mm. The above combinations resulted in three
slenderness ratios, of 9.7, 18.0 and 34.7 (where=L/r=L/0.3D). The
columns in each group of the same slenderness ratio were geometrically
similar.
