Performance based design (PBD) is an iterative exercise in which a preliminary trial design of the building structure is selected and if the selected trial design of the building structure does not conform to the desired performance objective, the trial design is revised. In this context, development of a fundamental approach for performance based seismic design of masonry infilled frames with ...

The evolution of the damage mechanic properties for un-reinforced masonry panels under dynamic loads is critical in a time-domain analysis of masonry shear walls. This research project experimentally investigates the evolution of the properties of the damage variable for unreinforced masonry panels, subject to dynamic in-plane displacement controlled strain. This paper presents the theoretical ...

At present, many of the historic masonry structures in the most important seismic zone of Argentina present damages due to the actions to which they have been subjected. Therefore, it is necessary to study the behavior of walls of ceramic masonry of great thickness. This work presents the comparison between the results obtained from the numerical simulation of ceramic masonry walls subjected to...

The application of steel fiber reinforced polymer (SRP) as a means of increasing the capacity of masonry columns is investigated in this study. The behavior of 23 solid-brick specimens that are externally wrapped by SRP sheets in low volumetric ratios is presented. The specimens are subjected to axial monotonic load until failure occurs. Two widely used types of masonry columns of differing squ...

Homogenization technique has been used to derive equivalent material properties of masonry units for many years. However, most of the previous research work concentrated on derivation of equivalent material properties for solid brick masonry structure. Very few studies have been conducted to investigate complex mechanical properties of hollow concrete block masonry unit. In this paper, homogeni...

The paradigm shift of digital fabrication encourages architects to incorporate the knowledge of using innovative materials and novel tools to solve problems in design and construction. However, the application of digital fabrication still needs more flexibility that allows different groups in a society to redesign fabrication processes based on their own needs and values. Looking at robotic fac...

Natural stone is a durable construction material which has been used through centuries for various types of structures. These structures are exposed to corrosive and degradation factors such as climate change and pollution, natural ageing, earthquake actions, increasing urbanization and even human negligence, potentially exposing them to irreversible structural damage and loss. Considering the ...

Recycled concrete brick (RCB) is manufactured by recycled aggregate processed from discarded concrete blocks arising from the demolishing of existing buildings. This paper presents research on the seismic performance of RCB masonry walls to assess the applicability of RCB for use in rural low-rise constructions. The seismic performance of a masonry wall is closely related to the vertical load a...

The equivalent periodic eigenstrain method is used to evaluate the effective elastic stiffness of periodic masonry structure. An Eshelby tensor, for a unit cell of the periodic masonry structure, is derived analytically, and is combined with a strain energy approach to formulate the effective stiffness of the masonry. The new homogenization scheme is simple, one step, and closed form. The model...
