NUMERICAL MODELING OF REINFORCED CONCRETE BEAMS, INCLUDING THE REAL POSITION OF REINFORCING BARS
Journal Title: Structure and Environment - Year 2018, Vol 0, Issue 1
Abstract
The article presents comparison of the results obtained from reinforced concrete beams experimental studies with the use of ARAMIS system (digital image correlation) with the results gained from numerical modeling. During studies, deviation from the plane of reinforced concrete beams was observed. Inventory of rebars positions in cross-section of this beams showed significant deviations. Analysis carried out in the work [1] revealed the impact of improperly embedded longitudinal reinforcement on the occurrence of horizontal displacements. Based on the collected data, numerical models of two selected reinforced concrete beams with correct and incorrect positon of the reinforcing bars were made using the Concrete Damaged Plasticity model in Abaqus software. It has been shown that premature interruption of the calculation appeared in models taking into account deviations in the position of reinforcing bars. However, the occurrence of horizontal displacements was still confirmed by numerical model for beams with incorrect positioning of rebars.
