Seismic Rehabilitation of Substandard R.C. Buildings with Masonry Infills [PDF]
Seismic deformation demands are localized in areas of stiffness discontinuity, such as in soft-storeys of frame structures, where disproportionate damage is often reported in post-earthquake reconnaissance. In many parts of the world this damage pattern is mitigated using strengthening schemes that include addition of stiffness in the structure so as ...

ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Abstract Accurate estimation of the damping ratio is critical for evaluating floor response spectra and equipment seismic demands in nuclear power plant structures. This study investigates the elastic damping ratio of reinforced concrete walls under limited damage states through shaking table tests and data‐driven modeling.

SEISMIC RESPONSES OF RC FRAME WITH DIFFERENT ARRANGEMENT OF MASONRY INFILL WALL
This study presents the suitability of using macro model (strut model) for analyzing the seismic responses of single-story single-span reinforced concrete frames having different arrangement of masonry infill wall with openings by comparing its results

Modern confined masonry (CM) construction consists of masonry walls confined by reinforced concrete (RC) tie‐columns and tie‐beams. When built correctly, CM buildings have shown good performance in earthquake's shaking. Even though CM construction has been practised for almost a century in some Latin American countries, its use and standardisation are ...

ABSTRACT The seismic capacity of structural systems/members is usually defined in terms of deformation thresholds. Although this is effective in many circumstances, disregarding cumulative quantities such as hysteretic energy may be ineffective when low‐cycle fatigue is relevant (e.g., long‐duration ground motions, very soft soils, ground‐motion ...

Seismic Meta‐Fragility Functions
ABSTRACT Fragility functions make for one of the three key components of probabilistic seismic risk analysis, along with hazard and consequence and/or exposure models. They are, in principle, construction‐specific; however, risk analysis is more often performed on a larger (e.g., regional) scale. In this case, so‐called typological fragility curves are
