Research on infilled reinforced concrete frames is fundamental for the vulnerability assessment of existing buildings. The analysis interaction between infill and frame an open issue in performance-based earthquake engineering due to its importance predicting dynamic behavior failure modes This study provides access database laboratory tests masonry frames, collected from literature harmonized ...

This paper presents laboratory test results for two-column one-bay reinforced concrete (R/C) bare frames with or without masonry infills 1:3 scale prototypes when the top beam is subjected to horizontal cyclic loading using 50kN axial load per column. It well documented that affect dynamic characteristics of building structures. At same time, their uncertain behaviors have also been recorded. M...

Transport and retention of colloid tracers were evaluated in standard petrographic thin sections, prepared from saprolite (Cr horizons) formed from fractured sedimentary rocks, using epi-fluorescence microscopy. Thin sections prepared from dismantled hydrogeological columns revealed four domains of macropores with apparent apertures ranging from 1 to 500 Am. Colloid retention occurred within bo...

CLT panels have been investigated for reinforcement of existing masonry-infilled RC framed buildings through the increase overall lateral stiffness structure, thus reducing story drift demand. The contribution depends on connection to frame elements. This paper evaluates role connectors by which is attached frames capacity, ductility, and energy dissipation structure its elements separately usi...

Anodic self-organized TiO2 nanotube layers (with different aspect ratios) were electrochemically infilled with CuInSe2 nanocrystals with the aim to prepare heterostructures with a photoelectrochemical response in the visible light. The resulting heterostructure assembly was confirmed by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray diffra...

To study the influence of masonry infill walls on hysteretic performance reinforced concrete frames, a cyclic experiment was conducted for three two-story and two-span frame structures, including one without two frames with walls. Whether were constructed in type infilled material main parameters test. The major results reveal that: clearly changed mechanical mechanism structure at early stage ...

Infills can highly influence the seismic response of a Reinforced Concrete (RC) building: generally speaking, their presence leads to an increase in global stiffness and strength, but their brittle behavior can result in an increase of displacement demand if a certain threshold of seismic intensity is overcome. Moreover, presence of infills often leads to a change in the collapse mechanism comp...

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...

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....
