Numerički model puzanja armiranih i prednapetih betonskih konstrukcija u ravnini ; Numerical modelling of in-plane creep behaviour of reinforced and prestressed concrete structures
Prikazan je numerički model za analizu deformacija puzanja betona u ravnini, utemeljen na korekciji modula elastičnosti u glavnim pravcima, za trenutno stanje glavnih naprezanja. Korekcija modula elastičnosti ovisi o trenutnom koeficijentu puzanja i trenutnom modulu elastičnosti dobivenom iz jednoosnog radnog dijagrama betona u tlaku. Na temelju izrađenog računalnog programa izvršena je analiza točnosti modela na odgovarajućim primjerima laboratorijski i numerički ispitivanih armiranih i prednapetih betonskih konstrukcija. ; The numerical model for the analysis of in-plane creep behaviour of concrete, based on the correction of the modulus of elasticity in principal direction, for the current state of principal stresses, is presented. The elastic modulus correction is dependent on the current creep coefficient and the current elastic modulus as obtained from the uniaxial diagram of concrete in compression. The model’s accuracy was analyzed on appropriate laboratory and numerical examples of reinforced and prestressed concrete structures, using a computer program developed for that purpose.
