Study of structure performances of invert T-type steel-reinforced concrete beams

摘要

Through analysis of tests and theories, in which parts of tension reinforcing steel bar in a reinforced concrete beam are distributed between the tension flanges of T-shape section of beams, this article describes their influence to performances of normal cross section and ultimate bending carrying capacity, sums up impacting factors that some of tension portrait reinforcement is distributed in the range of tension flanges of T-shape section of beams, confirms the tension portrait reinforcement area and the effective width of tension flanges in that of T beams.
