Load-Bearing Capacity of Mechanical Fastening in Lightweight Concrete

In traditional masonry construction, roof trusses are anchored to walls using conventional anchors embedded directly into the reinforced concrete ring beam. However, in lightweight structures, installing a ring beam may impose an additional load on the wall, which may not necessarily improve its bearing capacity. The use of lightweight concrete, due to its specific properties, represents a significant advancement in modern construction, but requires special consideration in the design of anchoring systems. Based on the anchoring solution proposed by the author, steel, galvanized, screw-type anchors installed directly into lightweight perlite concrete blocks were assumed. Experimental tests and analyses of these anchors provide a basis for the development of design approaches for lightweight structures. The results demonstrate the feasibility of using bonded anchors in perlite concrete and indicate their potential applicability in practical engineering design.
