The removal of building deflections consists of uneven raising of buildings with piston hydraulic jacks. A stack of parallelepiped steel elements is situated under jacks during defl ection removal for technological reasons. The stack has decisive influence on the stiffness of the supports. Tests of the stack of parallelepiped elements loaded with increasing and decreasing force were designed and carried out. Three characteristic phases were identified based on the tests. The maximum stiffness in particular phases was, respectively 13.1, 63.1 and 10.1% of theoretical stiffness.
