During the analysis of reinforced concrete structures, the infill wall is usually simplified as a diagonal inclined strut to facilitate finite element modeling calculations. However, the actual seismic damage and single frame-filled wall pushover experimental results show that when the earthquake shear force is huge, the top of the infill wall and the beam–column connections are usually, thus t...

Masonry infill walls are critical components of reinforced concrete (RC) frames, which may be damaged even under earthquake events moderate intensity, thus resulting in significant losses. Recent experimental and numerical studies have investigated innovative solutions for protecting these by reducing their interaction with the RC frame. Among these, specially shaped rubber joints were develope...

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...

Masonry is one of the world’s most durable construction materials. Masonry structures can remain in service for hundreds or even thousands of years. Masonry structures often outlive their designers, their original design documents, and their original functions. When historic masonry structures are evaluated for preservation, adaptive use, or additions, there are numerous questions that may aris...

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 direct modeling of masonry infill walls on many buildings, based damage recorded by various past earthquakes, has become increasingly necessary in order to identify the seismic behavior these elements, which constitute an important part reinforced concrete buildings. In this paper, several 3D models were analyzed nonlinear static (pushover) method, when ignoring, and considering, walls. fin...

High raised buildings are vulnerable to the lateral loads caused during natural calamities like earthquakes and cyclones. Lateral loads always affect the stability of structures. The shear walls, which are provided to resist these lateral forces, are often considered undesirable from utility point of view as they come in the way of vehicular movement in the parking area. Methods to evaluate the...
