In this paper, we propose an assembled self-centering buckling-restrained brace (ASCBRB), which eliminates the residual drift of structures after a major horizontal displacement. The ASCBRB also represents advanced device for partial replacement damaged parts brace. Four groups prestressed disk springs and metal yielding core plate were used to improve resilience energy dissipation brace, respe...

In order to improve the force performance of traditional anti-buckling energy dissipation bracing with excessive non-recoverable deformation caused by strong seismic action, this paper presents a prestress-braced frame structure system shape memory alloy (SMA) and investigates its characteristics under horizontal load. Firstly, establishes theoretical analysis model analyzing geometric relation...

This article explores the impact of dual pandemics COVID-19 and White rage on critical consciousness-raising. It argues for a reimagining our democracy as practice collective liberation. then outlines framework social justice that moves beyond liberalism to self-interrogation, centering historically minoritized voices, accountability.
