PRESTRESSED SHEAR REINFORCEMENT IN PRESTRESSED CONCRETE BEAMS

VORGESPANNTE SCHUBBEWEHRUNG IN SPANNBETONTRAEGERN

CLARIFICATION OF THE SUPPORT EFFECT OF THE WEB STRUCTURE (STRESSING OF MEMBERS AND PRE-STRESSED SHEAR REINFORCEMENT AS WELL AS THE STRESSING OF DIAGONAL STRUTS). EXAMINATION OF THE DEVELOPMENT OF DIAGONAL CRACK WIDTHS. EXAMINATION AND SUBSEQUENT IMPROVEMENT OF EXISTING DIMENSIONING REGULATIONS FOR PRE-STRESSED SHEAR REINFORCEMENT. THE CARRYING OUT AND EVALUATION OF A GIRDER TEST IS PLANNED AS A CONTINUATION OF THE THEORETICAL PRELIMINARY WORK (GIRDER WITH I-CROSS-SECTION, PRE-STRESSED SHEAR REINFORCEMENT INCLINED AT AN ANGLE OF 45 DEGREES, L = 660 CM, D(0) = 90 CM).
