RESTRICTION OF SLACK REINFORCEMENT TO ABSORB TENSILE FORCES IN ORDER TO LIMIT CRACKING IN PRESTRESSED CONCRETE

SINNVOLLE BEGRENZUNG DER SCHLAFFEN BEWEHRUNG ZUR AUFNAHME DER ZUGKRAEFTE FUER DIE RISSEBESCHRAENKUNG IM SPANNBETON

BY MEANS OF THEORETICAL CONSIDERATIONS AND EXPERIMENTAL INVESTIGATIONS OF AT LEAST SIX SELECTED PRESTRESSED CONCRETE GIRDERS, AN ATTEMPT IS TO BE MADE TO EXPLAIN WHETHER IT IS A GOOD IDEA TO HAVE ADDITIONAL REINFORCEMENT FOR COMPLETE ABSORPTION OF TENSILE FORCES TO LIMIT CRACKING OR WHETHER NORMAL OR SLIGHTLY EXPANDED MINIMUM REINFORCEMENT IS SUFFICIENT.
