Abstract

Often during a reconstruction of historical buildings it is necessary to repair or replace damaged element of the structure by a new part. In such situation it is inevitable to reach a stage when the damaged part is not statically stressed. The deformation tensometric measurement was used to monitor and verify stress changes during reconstruction. Electric resistive strain gauges were glued mainly on the supporting metal structure or directly on repaired parts. In this paper some examples how this method was applied are demonstrated on the three structures: - Reparation of the sandstone portal in the Prague Castle Picture Gallery - Measurements of deformation changes in tensile rods for static securing of the lateral wa
