Seismic restraints are designed to resist the horizontal seismic force in two primary directions: Transverse (perpendicular) and Longitudinal (parallel) to the run. The braces are attached to the building with a structure attachment (for concrete, steel, wood, etc. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions. Why is seismic bracing important? International Building Code. This article will explore the importance of seismic resistance in cable trays, discuss when seismic braces are necessary, and help you understand how to make informed decisions for your installation. Supports for these systems are typically sized to carry approximately a 10 ft length of conduit or duct (in the case of trapezes, ultiple pieces of conduit each approx 10 ft long). The ease of. The B-Line series seismic bracing cable kits, featuring the patented KwikWireTM tool-less clamp, are up to 50% faster to install over traditional cable bracing methods.
