STUDY ON CALCULATION METHODS OF NORMAL SECTION BEARING CAPACITY OF STEEL REINFORCED CONCRETE BEAMS

摘要

In this paper, calculation formulas of normal section bearing capacity of steel reinforced concrete (SRC) beams are derived both when the neutral axis passes through the upper flange of the steel and when the neutral axis does not pass through the steel according to the calculation methods and the assumptions from the Technical Specification for Steel Reinforced Concrete Composite Structures (JGJ138 - 2001). The calculation results of proposed formulas agree well with the experimental results and can be used as references for the structural design.
