A novel seismic connector for precast concrete shear walls

Structural Concrete, EarlyView.
Abstract A critical aspect of the seismic performance of precast concrete walls is the deformation capacity of their connections, which can be limited by premature bar fracture, reinforcement buckling, or cyclic instability. This paper introduces and experimentally validates a new ultra‐ductile connector (UltraDC) that provides reliable force transfer ...

Access to Trauma Care for Patients With Proximal Femur Fractures in Resource‐Limited Settings: A Prospective Cohort Study in Rural Tanzania

World Journal of Surgery, EarlyView.
