Ductility improvement of GFRP-RC beams using precast confined concrete block in compression zone

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 10,   Pages 1585-1598 doi: 10.1007/s11709-023-0968-8

Abstract: However, owing to the lack of ductility in this material and the quasi-brittle behavior of concrete,FRP-reinforced concrete (FRP-RC) beams, even with flexural failure, do not fail in a ductile manner.FRP-RC beams depends on the ductility of their compression zones, the present study proposes using a precastconfined concrete block (PCCB) in the compression zone to improve the ductility of the beams.

Seismic design and analysis of a high-rise self-centering wall building: Case study

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 11,   Pages 1690-1706 doi: 10.1007/s11709-023-0022-x

Abstract: Post-tensioning self-centering walls are a well-developed and resilient technology. However, despite extensive research, the application of this technology has previously been limited to low-rise buildings. A ten-story self-centering wall building has now been designed and constructed using the state-of-art design methodologies and construction detailing, as described in this paper. The building is designed in accordance with direct displacement-based design methodology, with modification of seismic demand due to relevant issues including higher-mode effects, second order effects, torsional effects, and flexural deformation of wall panels. Wall sections are designed with external energy-dissipating devices of steel dampers, and seismic performance of such designed self-centering walls is evaluated through numerical simulation. It is the first engineering project that uses self-centering walls in a high-rise building. The seismic design procedure of such a high-rise building, using self-centering wall structures, is comprehensively reviewed in this work, and additional proposals are put forward. Description of construction detailing, including slotted beams, flexible wall-to-floor connections, embedded beams, and damper installation, is provided. The demonstration project promotes the concept of seismic resilient structures and contributes to the most appealing city planning strategy of resilient cities at present. The paper could be a reference for industry engineers to promote the self-centering wall systems worldwide.
