Application of steel in refurbishment of earthquake-prone buildings

Građevinar, 2020
Refurbishment of existing buildings has become an increasingly topical issue in recent years. The recent Zagreb earthquake has also increased public awareness about the issue of sensitivity of old buildings to seismic loads.

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 ...

Seismic performance enhancement of underground structure influenced by CFRP wrapping schemes

Urban Lifeline
The seismic failure mechanism of underground structures showing structural collapse is attributed to the deformation incompatibility between the central columns and the sidewalls, especially the insufficient deformation capacity of the central columns ...

Seismic analyses of a R/C building: study of a retrofitting solution [PDF]

, 2000
The preliminary experimental results from the tests on a 4-storey R/C frame structure are presented and discussed. The full-scale model is representative of the common practice of 40~50 years ago in most south European countries.

For the Few, Not the Many: Tracing the Residualist and Compensatory Nature of British Energy Support

Environmental Policy and Governance, EarlyView.
ABSTRACT Drawing on extensive documentary analysis, this article traces the evolution of British energy policy support since World War II. It analyses shifts in policy design through two interpretive lenses: eligibility (residualist vs. universalist) and function (compensatory vs. preventive).

Seismic Retrofit of an Existing RC Building With Isolation Devices Applied at Base

Frontiers in Built Environment, 2020
Nowadays, seismic retrofit through isolation strategy represents a consolidated technique of protection against design earthquakes. This technique is also applied on existing structures extensively, due to the fact that it usually does not require any ...

Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Seismic Capacity of R/C Buildings Retrofitted with a V-Bracing System Equipped with a Novel Laterally Layered Friction Damper

Applied Sciences, 2023
This study proposed a novel V-bracing system equipped with a laterally layered friction damper (LLFD), which can supplement the shortcomings of conventional vibration control systems and is applicable to existing reinforced concrete (R/C) buildings.
