Response Modification Factor of RC Frames Strengthened with RC Haunches [PDF]
Shock and Vibration, 2020 This paper presents experimental and numerical studies carried out on two-story reinforced concrete (RC) frames having weaker beam-column joints, which were retrofitted with reinforced concrete haunches to avoid joint panel damage under seismic actions ...

Behaviour of Strengthened RC Frames with Eccentric Steel Braced Frames [PDF]
E3S Web of Conferences, 2017 After devastating earthquakes in recent years, strengthening of reinforced concrete buildings became an important research topic. Reinforced concrete buildings can be strengthened by steel braced frames.

Damage Sensitive-Stories of RC and Steel Frames under Critical Mainshock-Aftershock Ground Motions [PDF]
Journal of Rehabilitation in Civil Engineering, 2022 Cumulated damages caused by the past earthquakes lead to structural damage. Ensuring the safety of individuals – especially in highly populated buildings – and the continuity of immediate occupancy in consecutive earthquakes with short periods is an ...

Seismic Performance Target and Fragility of Masonry Infilled RC Frames under In-Plane Loading
Buildings, 2022 Masonry infilled RC frames are one of the most common structural forms, the damage of which, in earthquake events, usually cause serious losses. The determination of the seismic performance target is the key foundation of performance-based seismic ...

Strengthening of RC Frames With Infill Walls Using High Strength Lightweight Concrete Panels
Journal of Sustainable Construction Materials and Technologies, 2023 This study proposed a practical seismic retrofit method for RC frames. For this purpose, a quasi-static loading was applied to 8 RC frames in finite element analysis software, Abaqus, and frames were pushed 45 mm laterally. High-strength fiber-reinforced
