Figure 8: Sketch of nylon strap locations in Tolles et al. (2000).
The nylon straps used in the experiments on 1:5 model buildings were 0.3cm in diameter,
flexible and woven. These looped vertically or horizontally around an entire wall or the whole
building. The nylon cross-ties were 0.16cm in diameter and reduced crack displacement as well
as providing through-wall connection.
