TILT-UP WALLS TEST RESULTS
A series of experimental tests were conducted to supplement existing physical test data on various slender tilt-up walls, and to expand the available test information to include some other types of walls commonly seen in practice, such as walls with two layers of reinforcement, isolated footings, concentrated loads, and panels with openings. Three significant conclusions have been made from these tests. (1) It was found that tilt-up walls with aspect ratios, h/t, as large as 60 can continue to sustain combined axial and lateral loads while loaded to deflected shapes well beyond wall cracking and first yield of the reinforcement. (2) Walls reinforced with two layers of reinforcing bars, one layer located near each face, provide a stiffer wall with higher ductility, when compared to a wall with an equivalent total amount of reinforcement placed in one layer near the panel midthickness. (3) A decrease in the size of isolated footings did not have a significant effect on the observed behavior or measured capacity of the tilt-up wall specimens.
