Analysis of Infilled Masonry Wall in Steel Frame Subjected to Lateral Loading by Experiment and FEM Software

Abstract

This paper describes the behaviour of infilled masonry wall in steel frame subjected to lateral loading. Construction of RCC structure is quite slower than Steel structure, though the cost of steel structure is high but time required for construction is less, moreover for temporary structure steel member and section are use on large scale as it can be reused also. In this study a rectangular steel frame of IS section ISMC 250 is made and lateral loading is applied through jack. Frame is infilled by fly ash units with thin mortar joint. Axial load is also applied on frame simultaneously, during experiment and data is analysed, same full scale model is simulated in FEM tool and result were compare and found that they valid each other, it was observed that in steel frame initially bond between masonry and steel frame section get separated and it try to overturn the masonry wall from toe and debonding at toe initiated but as it is bounded and lock in channel section it stress transfer to heel side of masonry and all stress is concentrated on heel and heel crushing take place.
