Seismic performance of RC frames strengthened by RC infill walls
Advances in Structural Engineering, 2021This study presents the shake-table tests of a 1/5-scaled RC frame retrofitted with RC infill walls. The intensity of input ground motions increased gradually to comprehensively evaluate the structural seismic behavior. We performed a comparison of the results from the RC frame with masonry walls and that with RC walls.

Experimental characterisation of load responses to failure of a RC frame and a NSM CFRP RC frame
Construction and Building Materials, 2013Abstract This paper presents results from loading to failure of two reinforced concrete (RC) frames. The control frame was under-reinforced with 0.94% tension steel in the beams. The second frame was as the control, with the additional use of up to 0.35% near-surface mounted tension CFRP reinforcement in the positive moment zone and one negative ...

Influence of infill wall in RC frames
Engineering for Rural Development, 2023The function of infilled masonry reinforced concrete (RC) frame buildings during severe events such as blast caused by explosions or earth movement – earthquake and other significant lateral displacement could seriously damage a supporting frame column, causing the frame to collapse completely or partially.

Comparison of Seismic Performance of Composite (RCS) Frame with RC Frame Using Pushover Analysis
2020In this paper, comparison of seismic performance has been investigated between RCS (Reinforced Concrete column-Steel beam) composite frame and RCC (Reinforced cement concrete) frame using SAP2000 software. Nonlinear static analysis (pushover) is employed for evaluation of the seismic performance of both RCS and RC frames. Both the RCS and RC frames are

Response of RC Frame under Lateral Loads
Journal of Structural Engineering, 1991The experimental response of a single‐story, indeterminate reinforced concrete (RC) frame with floor slabs is investigated in this paper. The frame was quarter‐scale and tested under static lateral‐load reversals simulating earthquake load. The internal force redistribution occurring within the inelastic range of response and the beam flexural ...

RC buildings retrofitted by converting frame bays into RC walls
Bulletin of Earthquake Engineering, 2013Adding concrete walls by infilling certain frame bays with reinforced concrete is popular for seismic retrofitting, but is covered by codes only if the connection of the old concrete to the new ensures monolithic behavior. To avoid penalizing the foundation of the new wall with a very high moment resistance, the new concrete should not be thicker than,

Strengthening of RC nonductile frames with RC infills: An experimental study
Cement and Concrete Composites, 2008Abstract The purpose of this study was to experimentally investigate the behavior of RC nonductile frames with RC infills under lateral loads. A total of six 1/3 scaled one bay, two story nonductile specimens were built and tested under reversed cyclic lateral load. Specimen frames were manufactured with the deficiencies commonly observed in practice.

Influence of Infill-to-Frame Connection on the Seismic Response of RC Frames
2023Existing reinforced concrete buildings subjected to medium intensity earthquake loads often exhibit significant damage to structural and non-structural components that may compromise the structural safety and the building repairability. This damage is commonly concentrated on infills and partitions leading to relevant economic losses.

Seismic retrofitting of RC frames with RC infilling (SERFIN Project)
2023The effectiveness of seismic retrofitting of multi-storey multi-bay RC-frame buildings by converting selected bays into new walls through infilling with reinforced concrete (RC) was studied experimentally at the ELSA facility of the Joint Research Centre in Ispra (Italy).
