Analysis of shear behaviour of masonry with hollow calcium silicate blocks

Abstract

This paper deals with analysis of shear behaviour of masonry with hollow calcium silicate blocks. The initial shear strength of the masonry depends on the composition and strength of the mortar, structural solution of the masonry units and some other factors. The shear strength of the masonry with calcium silicate hollow blocks and thin layer bed joints depends on compression stress σvp, curing condition of the mortar for the bed joints. The character of shear deformations of the masonry subjected to shear is governed by structural peculiarities of the blocks, i.e. by keys of the mortar formed in the holes of the blocks. Analysis of experimental results and analytical calculation according to Lithuanian design code and to Eurocode show that initial shear strength in Eurocode are taken greater than Lithuanian code.
