Tests on timber frame walls under in-plane forces: part 2

The mechanical behaviour of timber frame shear walls subjected to in-plane forces has been investigated through full-scale tests. Eleven monotonic and 11 cyclic tests were performed on full-scale shear walls, each 2.5 m high and 2.5 m long. Different variables were changed during the tests as follows. Different vertical loads were applied, different angle brackets and hold-downs were used and different sheathing panels were connected to the timber frame. Also, the influence of openings was investigated. Furthermore, two walls with non-structural finishing were tested in order to correlate the inter-storey drift with the level of damage. This paper (part 2) reports on a comparison between different test results, permitting evaluation of the influence of each variable on the stiffness and the resistance of the walls. Moreover, the theoretical formulae presented in a companion paper (part 1) were compared with the outcome of the tests, and good agreement was found. The racking resistance predicted by Eurocode 5 was also checked using the data obtained from the tests.
