Abstract

Abstract

Design value in codes and regulations at present stage is mainly based on test results of small size specimens,which is different from large-scale structure in practical engineering.It was collected test data of RC simple beams in different bearing stage,including deflection,bearing capacity,steel strain,concrete strain,and etc.The total number of specimens was 13.Test results indicated that size effect on flexural behavior was mainly reflected in yield stage of longitudinal reinforcement and failure stage of concrete.Size effect of concrete materials was reflected in mechanical properties of RC beams in yield stage.This kind of negative size effect was not significant.Safety of related bearing capacity theories was indirect verified in research scale.It was necessary to consider the composition of deformation which would be decided by much factors.According to different evaluation target,plastic rotation ability should be analyzed at ultimate bearing state or maximum loading state.
