It is the great change of Design of Connecting Beam.In full cast-in-place structural, even if setting X-type to concentrate arrangement of reinforcement in concrete connecting-beam, also much up to not
To such ductility effect.The force-displacement curve of the normal concrete coupling beam of prior art, as shown in Figure 8, X-shaped is anti-buckling
