| This thesis has built the analysis model of the shearing wall based on ZW eccentric compression and shear wall testing analysis. And it has made use of large-scale common software ANSYS to carry out static analysis. The eccentric compression and shear load-bearing capacity calculations accorded with the test value well and the correctness of the analysis model has testified.Based on the analysis above, impact of the bearing capacity of concrete strength and axial compression ratio and shear span ratio and reinforcement ratio was discussed by building new analysis models about ZW shear wall with different parameters.In conditions of the same reinforcement ratio and axial compression ratio, when C20-C40, with the increasing of concrete strength, the shear load-bearing capacity of ZW shear wall is increased. But the ultimate bearing capacity at the level C45 equals to the C40's, and judging from the graphics, there is a downward trend in bearing capacity of the greater strength of concrete.In conditions of the same concrete strength and reinforcement ratio, with the increasing of axial compression ratio ofσ/f, the eccentric bearing capacity of ZW shear wall is increased. The effect of axial compression ratio on the shearing wall as follows: whenσ/f =0.192-0.288, the shear load-bearing capacity of ZW shear wall is increasing; Whenσ/f =0.288-0.320, the failure modes will change and pressure is a major disruptive factor. With the increasing of shear span ratio, the ultimate shear capacity of ZW shear wall has declined. Whenλ=2.16-2.45, under the end stiffener, the average decline is 14.3% and 11.3% when no end stiffener, the effects of shear span ratio is significant; Whenλ=2.66-2.94, under the end stiffener, the average decline is 6.5% and 4.4% when no end stiffener, the effects of shear span ratio is not obvious.At loads, steel truss can support and connect two concrete walls, and there is no separation of concrete slab but coordination. The longitudinal reinforcement in the steel truss can withstand the pressure and shear and improve the bearing capacity indirectly. With the increasing of reinforcement ratio and strengthening of the end stiffener, the shear load-bearing capacity is becoming to grow progressively at eccentric compression and shearing force. |
