Bridge Bearing Layout Method of Bridge Structures
The present invention relates to a method for arranging a bridge support of a bridge structure, which can mix and arrange lead earthquake-isolated supports and friction type lead earthquake-isolated supports to efficiently respond to a wind load and an earthquake load while securing stability and economic feasibility even when applied to a bridge to which the wind load is greatly applied. Provided is the method for arranging a bridge support of a bridge structure, which arranges friction type unidirectional lead earthquake-isolated supports having a guide bar on the first and last rows of an abutment and a pier, arranges lead earthquake-isolated supports in positions except the first and last rows of the pier, and arranges friction type bidirectional lead earthquake-isolated supports including a stainless plate and a friction material in positions except the first and last rows of the abutment, thereby supporting the wind pressure even on the bridge structure to which the wind pressure is greatly applied by the friction type unidirectional lead earthquake-isolated supports having the guide bar arranged on the first and last rows, sufficiently supporting the earthquake load by absorbing and dissipating energy by strength of the friction material of the friction type lead earthquake-isolated supports and a lead rod of the lead earthquake-isolated supports even in case of the earthquake, and allowing restoring force to be formed by the lead earthquake-isolated supports after the earthquake load. Also, the method for arranging a bridge support of a bridge structure additionally arranges the friction type bidirectional lead earthquake-isolated supports having the stainless plate and the friction material on the first and last rows, thereby offsetting the load in case of the earthquake when a width of an upper plate of the bridge is wide.
