Permanent Bracing for the Various Planes of a Truss Arriostre Permanente para Varies Pianos de un T11rusts Permanent bracing is important because it, a) prevents out -of -plane buckling of truss members, b) helps maintain proper truss spacing, and C) resists and transfers lateral loads from wind and seismic forces.
