A precast reinforced concrete frame constructed with new hook-end joint at both beam-column connections was numerical modelled and analysed using Finite Element Method, for its overall strength attainment under the action of horizontal cyclic loading. Five different thicknesses of U-shaped HDR, ranging from 15 to 35 mm thick in 5-mm intervals, were assigned in the numerical model as the vibrational absorber component in between the hook-end beam-column joints. The numerical force-displacement curves showed that precast frame with various thicknesses of U-shaped HDR had similar shape of hysteresis loops among each other. However, the precast frame with 25 mm thick of U-shaped HDR at its hook-end beam-column joint demonstrated the capacity to fulfil the highest force and displacement demands when compared with other thicknesses of HDR.
