Anchoring Guide Rails under Seismic Conditions

摘要

Specific design for seismic conditions is required in an increasing number of fields of construction. Cast-in steel plates connected to rebars before the concrete is poured are commonly used today for anchoring. Guide rail brackets are welded to the steel plates. Up-to-date anchoring solutions for seismic conditions use either cast-in inserts connected to rebars or post-installed anchors. In each case, the rail brackets are fastened by bolts. The design of such anchoring systems follows North American and European standards for seismic conditions. This paper provides an introduction to anchoring solutions for seismic conditions plus the specific approvals and design approach required to comply with these approvals.
