Results
Static-Cyclic Tests Failure modes of all the wall specimens of static cyclic
testing introduced in Fig. 6.32 are shown in Fig. 6.43. Comparison of parts
A-I, B-I, and C-I of this figure indicates that existence of openings can greatly
influence the crack pattern of the adobe walls. Openings corners and pier
between openings are more susceptible of experiencing shear cracks even at ini-
tial stages of testing.
