STATICAL SHEAR STRENGTH ON COUPLING BEAMS OF REINFORCED CONCRETE[J]. Journal of Civil and Environmental Engineering, 1994, 16(4): 1-10. DOI: 10.11835/j.issn.1674-4764.1994.04.001.
On the basis of a statical test of 16 specimens of coupling beams in shear walls
which consist of 10 specimens with ordinary rinforcement and 6 specimens with composite reinforce-ment
the statical behaviors of the coupling beams with two different types of reinforcement arestudied.It is concluded that the flexural strength 0f the beam should be multiplied by a reductionfactor when the span-depth ratio is less than 2
and the shear strength is not influenced by the span-depth ratio and may be obtained with unified calculation formula.
