Abstract: Since the Aceh 2004 earthquake, significant work has been conducted to assess the vulnerability of structures in Singapore and Peninsular Malaysia. However, it is believed that the existing assessment is conservative, yielding high peak ground acceleration. A research is done to re-evaluate the ground motion prediction in this region by conducting probabilistic seismic hazard analysis. Subsequently, a pushover analysis is conducted to an 18-storey building to assess its performance. The critical member that will fail in ductile shear failure is the intermediate length link-beam. Experimental study is conducted on 4 link-beams of intermediate length with double curvatures. To better estimate its behaviour, finite element models are developed using ABAQUS. Due to its short length-to-depth ratio, non-linear strut and tie model is used to model the load-deformation capacity of the beams. Finally, a new shear strength model is developed, taking into consideration strain in longitudinal steel to predict the shear degradation.
