ZW shear wall body eccentric compression and shear specimen test analysis based on the analytical model of the ZW shear wall wall and large general-purpose software ANSYS static performance analysis eccentric compression , to prove the correctness of the analytical model and the shear capacity analysis with the experimental results are in good agreement. Parameters enlargement on the basis of analysis of the the ZW eccentric compression and shear shear wall wall, using ANSYS program more in line with the test specimen conditions different axis compression ratio, shear span ratio ZW shear wall model and static load analysis, to explore concrete strength, axial compression ratio, shear span ratio, longitudinal stiffener parameter the ZW wall bias, the influence of the shear capacity situation. Same reinforcement ratio and axial compression ratio, concrete strength grade C20-C40, eccentric compressive the the specimen carrying capacity increases with the increase of the strength of concrete; concrete strength grade C45, the limit bearing capacity is equal to C40 ultimate bearing capacity, from the graphical trend view, with the increase of the strength of concrete, the ultimate bearing capacity increases downward trend. Under the conditions of the same concrete strength and reinforcement ratio, eccentric compression bearing capacity increase with axial compression ratio σ / f increases. Axial compression ratio σ / f shear capacity: When σ / f = 0.192-0.288, with the increase of axial compression ratio, shear capacity of the specimens to improve; When σ / f = 0.288- 0.320, the failure pattern of the specimen will change under pressure to play a controlling role in the damage, shear capacity decline. With the increase of shear span ratio, shear capacity of the specimens gradually reduce: when λ = 2.16-2.45, end ribs, dropped by an average of 14.3%, the endless ribs, dropped by an average of 11.3 shear span ratio greater impact; ends ribs, an average decrease of 6.5% when λ = 2.66-2.94, the ribs without end role, with an average decrease of 4.4%, no significant effect of shear span ratio . ZW wall loads, reinforced grid of two concrete walls play a supportive and connected the two concrete slabs coordinated the work, the entire process by the separation wall. The longitudinal reinforcement rebar grid can withstand the pressure and shear directly in the cross section, thus indirectly improving the carrying capacity of the specimen. And as the reinforcement ratio increases and the end of the wall to strengthen the role of the reinforced specimen under the eccentric pressure and shear forces, carrying capacity has significantly improved.
