Studies of Efficiency of Tie Rod Usage for Masonry Wall Strengthening
Journal Title: Металлические конструкции - Year 2018, Vol 24, Issue 3
Abstract
In the paper the influence of nontensional horizontal steel tie rods installation in a building perimeter on vertical and horizontal deformations of bearing walls of stone buildings is considered. Buildings of large blocks and bricks, loaded with constant and temporary loads were taken as initial data. By the way of the special effects it has been given ground vertical shifts which are accorded to mould radii of displacement through underworking. The stress-strain state of buildings was determined on the basis of numerical calculations using 3D models. The dependence of wall deformations from an area of ties to be installed at each floor level was obtained. For generalization the values of deformations were received as a function of an uneven relative settlement. It has been determined that the horizontal deformations is reducing up to 1,5…2,5 times (efficiency factor of 0,67…0,4) while a relative settlement does not exceed of 0,004. The research has demonstrated a usage of untensioned tie rods to be not effective in all for masonry wall strengthening.
