ΠΡΟΣΟΜΟΙΩΜΑ ΜΗ ΓΡΑΜΜΙΚΗΣ ΣΥΜΠΕΡΙΦΟΡΑΣ ΥΠΟΣΤΥΛΩΜΑΤΩΝ Ο/Σ ΣΕ ΑΝΑΚΥΚΛΙΖΟΜΕΝΗ ΔΙΑΞΟΝΙΚΗ ΚΑΜΨΗ ΜΕ ΟΡΘΗ ΔΥΝΑΜΗ ΚΑΙ ΕΦΑΡΜΟΓΗ ΓΙΑ ΤΟΝ ΥΠΟΛΟΓΙΣΜΟ ΤΗΣ ΑΝΕΛΑΣΤΙΚΗΣ ΣΕΙΣΜΙΚΗΣ ΑΠΟΚΡΙΣΗΣ ΚΑΙ ΠΛΑΣΤΙΚΟΤΗΤΑΣ ΟΙΚΟΔΟΜΙΚΩΝ ΕΡΓΩΝ ΣΤΟ ΧΩΡΟ

AN INCREMENTAL MODEL IS PROPOSED FOR THE NONLINEAR RELATIONSHIP BETWEEN THE NORMAL ACTION EFFECTS N, MY AND MZ, AND THE CORRESPONDING CROSS-SECTIONAL DEFORMATIONS, EO, ΦΥ, AND ΦΖ, OF RECTANGULAR REINFORCED CONCRRETE CROSS-SECTIONS. THE INCREMENTAL RELATIONSHIP IS OF THE BOUNDING SURFACE PLASTICITY TYPE: THE BOUNDING SURFACE OF THE CROSS-SECTION, WHICH CORRESPONDS TO ULTIMATE STRENGTH, IS CONSTRUCTED IN THE STRESS SPACE OF N-MY-MZ AND THE PLASTIC MODULI OF THE INCREMENTAL FLEXIBILITY OF RIGIDITY RELATION AND FUNCTIONS OF THE DISTANCE OF THE CURRENTSTRESS POINT FROM THE BOUNDING SURFACE, ALONG THE CURRENT DIRECTION OF INCREMENTAL LOADING. THE FUNCTIONAL DEPENDENCE OF THE BOUNDING SURFACE AND OF THE PLASTIC MODULI ON THE AMOUNT AND DISTRIBUTION OF LONGITUDINAL AND TRANSVERSE REINFORCEMENT IS GIVEN, ALONG WITH THE COUPLING TERMS BETWEEN AXIAL DEFORMATION AND CURVATURES IN THE INCREMENTAL FLEXIBILITY RELATION. THE SIMPLE HYSTERESIS RULES,WHICH MAKE THE MODEL APPLICABLE FOR ARBITRARY LOADING PATHS IN THE N-MY-MZ SPACE, INCLUDING ANY REVERSALS, ARE ALSO DESCRIBED.
