EFFECT OF PRESTRESSING ON CONCRETE BRIDGE COLUMNS
Published 2019-02-01“…As for the effect of the structure height, samples from shorter columns tend to have minor damage and stress and, in general, better behavior in comparison to the samples from longer columns.In addition, concrete compressive strength plays an important role in prestressed members behavior; however, uncontrolled increase in concrete compressive strength could have a negative effect on the structure behavior.…”

PROGRESSIVE COLLAPSE RESISTING CAPACITY OF TUBES IN TUBE STEEL STRUCTURES UNDER SEISMIC LOADS...
Published 2015-08-01“…The structures have been analyzed using time-history dynamic analysis.Because of the formation of plastic hinges under seismic loads at the height of this type of structure, the elements removed were modeled with hinges that had not been placed in the first story but had spread to the other stories.The plastic hinges formed under increased seismic loads in the elements have been modeled by elements with hinges that can resist a portion of the bending moment.Results show that by increasing the distance between columns in the 30 and 45-story tube in the tube structure, the chance of progressive collapse increases. …”
