In these tests that have been elaborated in the research papers, the shear wall panel gets subjected to earthquake condition and the behaviour of NI-TI alloy bars is observed in terms of the shear resistance of the shear wall. A comparison is made in between the conventional steel reinforcement with the modern day Ni-Ti alloy reinforcement.
Apart from the individual performance of the CLT in earthquake situation, it is further considered that how the performance of the same shear timber wall gets affected with the introduction of smart material like shape memory alloy of NiTi as reinforcement. Though, there are different options by which the NITi alloy can be entered into the wooden wall panel which serve as the major load carriers of the prefabricated timber structures as a whole However, in this study, the insertion of NiTi reinforcement into the wooden wall panel is done from the bottom of the wall panel. The timber wall panels are the plane boards that are usually the weaker part of the complete timber structure and they therefore need to be reinforced to support and provide additional strength to the structure. It is essential to reinforce the timber wall panels so as to make sure that the member is ductile and can resist against the wind loads and seismic waves, especially when the building has multiple storeys. (Dobrila & Premrov, 2003)
Dobrilla & Premrov (2003) further explained that the position of the associated materials for strengthening may affect or may not affect the resistance and ductility because the use of additional fibreboards (advanced construction material) with the wood shear wall panel did not show any potential improvement in the resistance and ductile property of the structure while the insertion of diagonal steel strips along with the fibreboards did show appreciable improvement.
