BACKGROUND Visual impairment associated with central field loss may make vehicle control more difficult due to the degraded view of the road. We evaluated how central field loss affects vehicle control in a driving simulator. METHODS Nineteen participants with binocular central field loss (acuity 6/9 to 6/60) and 15 controls with normal vision drove 10 scenarios, each about eight to 12 minute...

Concentrically braced frames (CBFs) are one of the efficient lateral load resisting systems in high seismicity regions.

Two-story X braced frames have more advantages than other configurations of concentrically braced frames, since in many cases th...
