ABSTRACT

The existence of masonry walls in structures is very useful in increasing the structure's resistance to lateral loads. The role of the walls is more important in providing adequate stiffness and damping than in resisting axial forces. The use of rubber tire crumbs (RTC) mortar on masonry walls is to increase the ductility and damping capacity of the wall. This study examines the application of RTC mortar on masonry walls, in particular for increasing the damping ratio of the wall. This study aims to determine the optimum RTC content in mortar by observing its dynamic properties using the shake table test. The specimens were 4 scaled models with mortar containing 10%, 20%, 30%, and 40% RTC. The prototype is a 3D half-brick wall 2.5 m high and a 2.5 x 2.5 m² plane, with a scale of 2 to provide a miniature model. There are 2 types of loads, namely sinusoidal loads and Yogya earthquake loads. The sinusoidal load has an amplitude of 0.1g with a frequency range between 4 Hz and 20 Hz, while the Yogya earthquake load has an amplitude between 0.1 g and 0.9 g. The results showed that the use of RTC mortar on the masonry wall structures can increase the damping capacity of the walls and reduce the drift ratio. This study recommends that the optimum RTC content is 30% of the sand volume.
