Abstract

Masonry walls with distinct layers, known as multi-leaf masonry walls, are prevalent in many regions of the world including ancient architecture in Europe and new construction in the Himalayan region of South Asia. This paper presents a model for determining the capacity of multi-leaf stone masonry wall from its physical and mechanical parameters. For the study, a “Standard Wall” with typical properties of a multi-leaf stone masonry wall is defined and the capacity of the stone masonry wall is studied varying different physical and mechanical parameters of the wall to explore an analytical model that can represent the capacity of multi-leaf stone masonry. 300 models of multi-leaf stone masonry panels are analysed in ANSYS, and the capacity and displacement parameters are extracted by bilinearization of the pushover curve. As a result, a mathematical model between the capacity of a multi-leaf stone masonry wall and physical and mechanical properties is established.

Highlights

Masonry structures occupy a huge stack of construction in the cities with ancient heritage and in rural areas of developing countries
In the Himalayan region of South Asia covering Nepal, India, Pakistan, and Afghanistan, stone masonry is used owing to the abundance of stones in these regions, easy construction, and good thermal insulation of thick walls of stone masonry
One of the early works in nonlinearity of masonry was by Tomazevic [1] followed by the simplified analysis method (SAM) [2]. en came modifications to SAM known as the equivalent frame method (EFM) [3,4,5,6]
