Seismic Retrofitting: The Unseen Hero of Earthquake Resilience

Seismic retrofitting is the process of modifying existing structures to make them more resistant to earthquake damage. With over 3 million buildings in the United States alone requiring seismic retrofitting, the stakes are high. The cost of retrofitting can be substantial, with estimates ranging from $10,000 to $100,000 per building, but the cost of inaction can be catastrophic. The 1994 Northridge earthquake, for example, caused $20 billion in damages, with much of that damage attributed to buildings that were not retrofitted. As the world's population becomes increasingly urbanized, the need for seismic retrofitting will only continue to grow. According to the United Nations, 68% of the world's population will live in urban areas by 2050, putting millions of people at risk of earthquake-related disasters. The seismic retrofitting industry is expected to grow to $10 billion by 2025, with companies like Simpson Strong-Tie and CoreBrace leading the charge. However, despite the growing demand, there are still many challenges to overcome, including the high cost of retrofitting, the lack of standardization, and the need for more effective technologies.
