SYNOPSIS   

The incorporation of seismic considerations into structural design became mandatory in Malaysia following the publication of the National Annex (NA) to MS EN 1998 in 2017. This shift was prompted by the devastating 2004 Indian Ocean earthquake and tsunami on December 26. Despite its proximity to the epicenter, Malaysia experienced relatively minimal damage—thanks to the shielding effect of Sumatra. However, northern coastal areas such as Penang and Langkawi, and parts of Perak, were impacted. Later, the 2015 Ranau earthquake in Sabah further emphasized Malaysia’s vulnerability, revealing the limitations of reinforced concrete and timber structures in seismic zones.

In response, High Damping Rubber Bearings (HDRB) have gained traction as a robust solution in seismic design, significantly improving structural resilience and reducing dynamic response. Research and global case studies—including seismic retrofitting of multi-span bridges—demonstrate HDRB’s effectiveness in minimizing deformation and enhancing occupant safety. Their integration is supported by international design codes, including guidelines from ASCE and JSCE, which advocate HDRB’s use in seismic-prone regions.

Malaysia’s Penang Second Crossing stands as a pioneering example of HDRB application, reinforcing the importance of adaptive design for long-term infrastructure durability. This study examines a seismic-prone infrastructure project utilizing HDRB, analyzing its structural behavior, mitigation strategies, and overall benefits. Through detailed evaluation, we aim to enhance understanding of HDRB’s role in resilient construction and promote best practices for seismic preparedness in Malaysia.

In conclusion, HDRB remain essential in modern infrastructure, offering a proven, adaptive approach to safeguarding against seismic forces.
