Paragraph starter
The research by Palazzo et al. (2011) demonstrates that buckling restrained braces, crucial for seismic energy dissipation, can be manufactured effectively and affordably using low-tech production processes. This approach is particularly relevant for developing countries, suggesting that advanced structural safety features do not always require high-cost, complex manufacturing, thereby enhancing accessibility and robustness.
