Australia might not be the first place that comes to mind when thinking about earthquakes, but seismic activity is a reality we can’t ignore. As our cities grow upwards and multi-unit residential buildings become more common, the need for earthquake-resistant design and construction is increasingly important. This is especially true in Melbourne, where recent tremors have reminded us of the importance of preparedness.
Key Components of Earthquake-Resistant Construction
Building a multi-unit residence that can withstand a shake-up requires careful planning and the right components:
• Foundation Systems – The bedrock of any building, literally. Earthquake-resistant designs often use deep foundations or specialised footings that can better distribute the forces of an earthquake throughout the structure.
• Structural Frame Design – Think of this as the skeleton of the building. Shear walls, braced frames, and moment-resisting frames are all common design elements that help a building absorb and transfer earthquake forces without collapsing.
• Material Selection – Not all bricks are created equal! Earthquake-resistant construction uses materials like reinforced concrete, steel, or certain types of timber that offer superior strength, flexibility, and elasticity during seismic activity.
Modern Techniques in Earthquake-Resistant Design
As our understanding of seismic behaviour advances, so do the techniques used to mitigate earthquake damage. Here are some cutting-edge approaches being adopted in Melbourne’s multi-unit residential buildings:
• Base Isolation – This technique involves separating the building’s superstructure from its substructure using flexible bearings or pads. During an earthquake, these isolators allow the ground to move beneath the building without transferring the full force of the motion to the structure above. While relatively new to Australia, base isolation is gaining traction in high-rise residential projects in Melbourne, particularly in areas with higher seismic risk.
• Energy Dissipation Devices – These innovative systems work by absorbing and dissipating the energy from seismic waves. Dampers – which function similarly to shock absorbers in cars – are installed within the building’s frame. During an earthquake, these devices convert kinetic energy into heat, reducing the overall force experienced by the structure. In Melbourne, we’re seeing an increasing number of multi-unit residential buildings incorporate these devices, especially in taller structures.
• Advanced Seismic Bracing – Bracing systems provide additional support to a building’s frame, helping it resist lateral forces during an earthquake. Modern designs go beyond traditional cross-bracing, incorporating eccentric braces or buckling-restrained braces. These advanced systems allow for controlled deformation, enhancing the building’s ability to withstand seismic forces without compromising its structural integrity.
