Towards the anchors behavior in multilayer building envelope with face brick layer

Abstract

Due to increasing regulatory requirements for exterior wall thermal insulation properties multi-layer building envelope is widely used. National practice of using multi-layer exterior walls revealed their increased deficiency. The strength properties of the anchor ties are not regulated and often unknown.Purpose of the study was to assess the state of the question, to analyze existing design solutions used in the construction in Russian Federation and also to conduct a series of laboratory tests to determine their bearing capacity of the main anchor ties currently used.The most common mistakes in applying anchors are analyzed. The results of foreign researchers are given. Two series of experimental studies of bearing capacity and deformability of anchors are presented. The dependencies of the pulling force on the type of anchors and strength properties of masonry mortar joints are obtained.
