The inelastic response of existing reinforced concrete (RC) buildings without seismic details is investigated, presenting the results from more than 1000 nonlinear analyses. The seismic performance is investigated for two buildings, a typical building form of the 60s and a typical form of the 80s. Both structures are designed according to the old Greek codes. These building forms are typical fo...

A common decay scenario in old and new buildings was simulated: the effects on masonry structures of salt efflorescence or subefflorescence produced by the rise of saline solution. Eight different types of masonry wall each made up of a combination of different construction materials (brick, calcarenite and four types of mortar were combined as follows: pure lime mortar, mortar + air entraining...

Water content affects mortar properties and the quality of the resultant masonry, however, it is often subjectively determined by the mason by assessing workability. This lack of explicit methodology and data, can lead to lack of mortar consistency and field performance, adversely affecting full uptake of lime mortars into mainstream technology. The aim of this research is to assist develop con...

Work in masonry is divided in different tasks and performed by sub-contractors. Sub-contractors specialize in a given skill to accomplish a specific construction task and usually work with crews. Due to this specialization, multiple crews with different skills are present on the jobsite at any one time and the sub-contractor is responsible of configuring crews to produce good quality work by me...

ABSTRACT This paper presents a non-linear finite element material model for the analysis of the mechanical behavior of multi-leaf masonry, which is quite frequently used in ancient stone masonry buildings. A damage model, previously developed by some of the authors for brittle materials (namely, concrete) was adapted to fit the experimental stress−strain behavior of stone masonry. To this end, ...

Cellular lightweight concrete (CLC) block masonry has gained popularity in the market with growing demand modern construction industry due to its various advantages, including a positive impact on environment. Subsequently, detailed characterization of vital engineering properties should be studied for development mathematical model, analysis, evaluation, and design structures made CLC masonry....

Approximately 30% of Turkey's population lives in rural areas and they are seated structures, which called unreinforced masonry building (URM). These types buildings consist mudbrick structures with wooden carcasses, masonry-adobe supports, brick briquette supported by reinforced concrete lintels. The construction is easy low cost because the availability materials such as masonry, so it freque...

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...

The purpose of this study is to explore three numerical approaches to the elastic homogenization of disordered masonry structures with moderate meso/macrolengthscale ratio. The methods investigated include a representative of perturbation methods, the Karhunen-Loève expansion technique coupled with Monte-Carlo simulations and a solver based on the Hashin-Shtrikman variational principles. In all...

Among the different non-destructive tests used to carry out an exhaustive survey about the mechanical and durability characteristics of a masonry made of solid tile-bricks, the ultrasonic method has experienced a wide diffusion thanks to its low costs and to its easiness of use; the method essentially consists in detecting the propagation velocity of ultrasonic pulses propagating through a soli...
