| Abstract: |
| The section bending stiffness of a fabricated concrete beam connected with section steel varies greatly due to the difference of construction practices.Based on the principle of superposition in small deformation theory,the deflection calculation method of this kind of member under load is proposed.According to the principle of equal deflection,the calculation formula of equivalent bending stiffness of the member is derived,and compared with the experimental results to verify the effectiveness of the formula.On this basis,the influence of parameters of steel reinforced concrete beams on the overall bending stiffness of variable stiffness members is analyzed.The results show that the steel connection method increases the flexural rigidity of the prefabricated concrete beam,reduces the deflection of the member under load,and is more beneficial to member and the structure. |
