Features and outline of the steel reinforced concrete composite structure are introduced. The calculating methods of the two existing regulation are described. The calculation method according to the“Technical specification for steel reinforced concrete composite structures”is more safely and reliably by comparing the calculation results and the experimental results. In non-seismic design, the simplified formula for calculating the shear strength is established by changing the sub-item coefficient of the concrete shear capacity based on the shear strength formula of the shear load-bearing SRC beams according to“Technical specification for steel reinforced concrete composite structures”. The experimental results are compared with the calculation results of the simplified formula, the results showed that experimental results have a good agreement with calculated results.
