Sažetak
Earthen architecture, even though still very present today, lacks meticulous research, especially in Croatia. Therefore, the aim of this research is to gain new insight on seismic behaviour of rammed earth walls. To accomplish that, two rammed earth walls were built using traditional techniques. In addition to that, preliminary numerical models were made using ANSYS (v. 2020 R2) software to predict load required for demolition of walls by pull down method. It was observed that out of two walls, built with 10 cm difference in thickness, the thicker wall achieves higher out-of-plane bearing capacity, of around 16 kN, while the thinner wall achieves out-of-plane bearing capacity of around 10.5 kN. Moreover, contrary to the initial opinion, thicker wall exhibited plastic behaviour at lower horizontal displacement. Therefore, it was observed that the thinner wall endured 20 % higher interstorey drift (IDR) before experiencing plastic behaviour. However, further numerical modelling and experimental testing of rammed earth walls are necessary.
