It was found that FRP confinement increased hollow RC columns' axial load and ductility capacities; and hollow columns having circular holes had better performance compared to hollow columns having square holes.
Six of the columns had a circular cross section (two solid columns, two hollow columns each having a circular hole, and two hollow columns each having a square hole) and the remainder columns had a square cross section (two solid columns, two hollow columns each having a circular hole, and two hollow columns each having a square hole).
Marino realized the damaging effect the Internet critiques often had on her, but she still struggled to keep herself from falling into the rabbit hole of columns, comments and fan message boards.
Measurement of the temperature profile of the lined-hole, water column (using a high sensitivity single-point probe achieving resolution on the order of 0.001 °C) has identified fractures with active flow under ambient groundwater conditions (without cross connecting flow along the borehole).
He logged six seasons of Cubs and White Sox duty, covered sports media and teed it up with more than 60 celebs for his "18 holes with" column.
These bolts were developed for installation in existing slabs by drilling holes around columns or concentrated load application points and then tightening against the slab surfaces.
The main results arising from the experiments were the ideal diameters of the holes' sections in several selected depths of material and the cylindricity, i.e. the difference of the real shape of the "column" hole from the ideal one represented by a column with ideal diameter.
The holes were arranged in five parallel columns with four holes in each column, and were designated numerically by the couplet (r, c), with the holes in the upper row as seen from the animal's working space designated (1, 1), (1, 2),..., 1, 5).
The statistical-regression model (SRM) is based on measurement of a set of column holes cut in a plan-parallel brass plate according to Box-Behnken design.
Similarly, in sample 4 with a column-like surface morphology, it is evident that vertical etching occurred only after the critical etching depth had been reached, and as a result, most of the nanocrystallites were located at the bottom of the etched column holes.
