“PARSANT”: A “Non Destructive” Method for Anti-Seismic Strengthening of Existing Buildings

Abstract eng:
The method refers to the anti-seismic strengthening of existing buildings with a framing system made of concrete, using additional strong exterior bracing panels, pin connected to the existing framing system. The panels are truss type plane systems made of steel composite members and have their own foundations. The pin connection is achieved using steel connectors (tie rods), which go through existing and additional beam members, bolted at both sides. With this method the construction damages to the existing buildings are minimized, without interruption of their use, and with minimum cost and construction time. Due to great rigidity and strength of the additional panels, the overall behavior of the buildings can comply with the recent antiseismic Codes. This paper describes briefly the method and presents the design of strengthening of an existing office building.
