In civil engineering, bracing is essential for ensuring that structures can withstand dynamic forces. Buildings and bridges often experience lateral forces resulting from environmental factors, such as wind pressure and seismic activity. Without adequate bracing, a structure’s integrity can be compromised, leading to potential failure. Steel pipe bracing serves as a reliable solution to these challenges, as steel is both strong and ductile, allowing it to absorb and dissipate energy effectively.
