Robust Design In The Analysis Of Low-shear Wall Shear Strength

The influence factor of shearwalls in shear strength have lot of, for example, shear to across the ratio,the rate of steel, concrete strength, load and frame etc. It is clear that low shearwalls is a key to inquiry into its extreme limit load breakage mechanism. Experiment and theories analysis express low shear walls the general occurrence shear to slice the breakage, Before shearwalls' concrete crack , The wall plate concrete under takes the big part shear stress , Exsist inclined pull lord should dint; After wall concrete crack, wall plate the reinforcing bar undertakes the big part shear stress, So changes to suffer the mechanism originally, hence formation the inclined direction suffers to press the piece of With suffer to pull the reinforcing bar pull, press the resistance. Carry the further enlarging along with the level load, the frame also participates the work, formation the inclined direction press. Experimenting the result expresses to shear the breakage of the shearwalls to produce in concrete wall plate generally, Carry the creation breakage in the frame pillar and then, Try at this time the piece attain the extreme limit loading . But current domestic and international tie to frames peace treaty in among them of the wall plate works together of suffer the shear mechanism complete not yet clarity, There is necessity very much further the research takes the frame low shearwalls the anti- of the shearwalls shear the function. The research of this lesson all has the bigger value from the applied aspect in a theories still an engineering regardless. Main research in this text contents:(1) the collections sorting is domestic and international and low shear walls anti- shears the strength experiments the data;(2) the robustness design in application method analysis influence shears the factor that shearwall anti- shear strength;(3) experiment the result take into with theories analysis the comparison. Because the influence is low to shear the factor that shearwall anti- shear strength more, And each factor returns the interaction. Study influence the method of the factor is still treated in further research. Can adopt the misty and robustness design method and base on to pull- press pole model method etc..
