In order to investigate the stress state and shear hysteresis effect of block 0 during the construction of a short tower cable-stayed bridge, a short tower cable-stayed bridge with a span combination of (85+160+85)m is used as an example. Block 0 was analyzed for stress state and shear hysteresis effect. The results show that the bridge in the maximum cantilever state 0 # block stress state is good, to the full cross-sectional compression; top and bottom plate to positive shear hysteresis effect, the top plate shear hysteresis change complex but small value, to meet the design specification requirements,. The analysis results can provide reference for similar bridge design and construction.
