Strengthening the Foundations of an Administrative Building in Moscow

Characteristic features of the construction and design of a building, the section of its location, and basic causes of deformation are discussed. The procedure used to strengthen the upper part of the foundations by the installation of tension rods consisting of vertical angle brackets, longitudinal channels, turnbuckles, and anchors, as well as reinforced-concrete belts-walls with effective longitudinal reinforcement in the upper and lower sections, and distributing horizontal and vertical reinforcement and anchors is described.__________Translated from Osnovaniya, Fundamenty i Mekhanika Gruntov, No. 2, pp. 19–23, March–April, 2005.     

Accelerated Testing of Foundations in Tamped Trenches

Accelerated testing of foundations subject to vertical-impressing and moment-induced loads in tamped trenches by loading them in individual steps to 0.5-0.7 of the assigned load (here, the settlement-load curve obtained is extrapolated to the design load), and also by their eccentric loading is described. Results are cited for tests of foundations in tamped trenches during construction of a number of entities in accordance with these procedures.
