Experimental assembly plan
To simulate a vertical permanent load, before each cyclic test a 2,000 kN vertical
load was applied via 6 cables arranged so that the result was close to the center of
inertia of the area. Three different cyclic tests were carried out on the u-structure
with the reaction wall: firstly, a USW1 test with horizontal loading along the Y-axis,
then a USW2 test with horizontal loading along the X-axis, and finally, a USW3 test
with horizontal loading along the X- and Y-axes.
