A comparative investigation on experimental lateral behaviour of bare RC frame, non-strengthened and ferrocement strengthened masonry infilled RC frame

Bulletin of the New Zealand Society for Earthquake Engineering
Although concrete framed structures are widely used with masonry infills, the contribution of masonry infills in structural design is limited to their dead loads only.

Study on Seismic Performance of RC Frame Structures Considering the Effect of Infilled Walls

Buildings
This paper studies the impact of half-height infilled walls on the failure modes of frame columns through quasi-static tests of both frame models and half-height infilled wall frame models.

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, EarlyView.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.

Experimental assessment and retrofit of full-scale models of existing RC frames [PDF]

, 2002
PSD tests on two full-scale models of existing non-seismic resisting RC frame structures are described. The testing program covered several aspects, namely assessment of seismic performance of existing frames without and with infill panels ...

Innovative development and structural behavior of hollow columns using inflatable molds

Structural Concrete, EarlyView.
Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

Cyclic behavior of GFRP strengthened infilled RC frames with low and normal strength concrete

Science and Engineering of Composite Materials, 2019
This paper presents the experimental behavior of plane, non-strengthened and glass fiber reinforced polymer (GFRP) strengthened infilled reinforced concrete (RC) frames with low strength concrete (LSC) and normal strength concrete (NSC) under lateral ...

Numerical Analysis of Masonry-Infilled RC-CLT Panel Connections

Buildings, 2022
CLT panels have been investigated for reinforcement of existing masonry-infilled RC framed buildings through the increase of the overall lateral stiffness of the structure, thus reducing the story drift demand.

Finite-discrete element modelling of masonry infill walls subjected to out-of-plane loads [PDF]

, 2016
In this paper, the out-of-plane response of infill walls is investigated by means of non-linear monotonic (push-over) analyses through a combined finite and discrete modelling approach.

Brittle failure in RC masonry infilled frames: The role of infill overstrength [PDF]

Engineering Structures, 2018
Abstract The interaction between an infill panel and a reinforced concrete (RC) column can lead to the brittle failure of the structural element. A novel combination of cutting-edge analytical modelling approaches for masonry infills and RC elements is employed to simulate five experimental tests (three infilled and two bare) characterized by brittle

Seismic Enhancement of Masonry‐Infilled Substandard Reinforced Concrete Frames Using Lightweight Steel Exoskeleton

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 603-623, March 2026.
ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...
