more cycles were added to the standard CUREE method with total of 43 cycles in order to fully
investigate post peak behavior of the walls, the CUREE loading history is shown in Figure 4.4 and
the parameters of each cycle is given in Table 4.1.
Monotonic tests are for determining the nominal shear strength for wind loads, it is also
safe approach to explore the performance of a new shear wall with unknown strength. Cyclic tests
are for determining the shear strength for seismic loads.
According to the testing method mentioned above, it is required to have at least two
identical tests for each wall configuration for each testing method. However, it is found that in the
past research (Yu(2013), Mahdavian (2016) & Zhang (2016), the results of the two monotonic
tests usually were consistent. Therefore, only one specimen were tested by monotonic test method
in author's research. For cyclic test, two identical specimens were tested.
