Composite shear walls shear walls included a sheet steel reinforced concrete wall with steel sheet can be. in one side or on both sides of the wall of concrete for steel sheet connection. of brshgirha such as picheha and shear CAP, etc. In the regulations of composite steel plate shear wall AISC, with mark (C_SPW).Taken in modeling using finite element software ANSYS and from the original frame width to height ratio of the squared frame and unit compliance and changes in the thickness of the concrete cover of steel sheet of thickness, and the connectors shall be focused. therefore two types of composite steel plate shear wall which overall includes 2 floors and walls have 3 floors, has been used in modeling.In the end, for each of the models has been drawing the chart histersis them. in the case of the type of curve shape is also due to the fact that the structures and dimensions of steel plate buckling prevention, soil as ice forms. If you do not use the harness for buckling, figures should have a flat slope and shape of S failed in May.The point here is important with this is that according to the hardness of concrete covering the steel sheets in the first stages of this decisive role in handling capacity will not play. And according to the hardness of concrete covered in evaluated samples of steel sheet preventing buckling, steel sheet in کمانشي after the behavior is virtually unanimously favorable, and this issue does not fall. The above story is true, that when the concrete shear wall is purely as a meharband for steel sheet. But due to the high hardness of concrete walls in addition to the fact that the model of concrete wall as a strong meharband for steel in sheet, during the loading began due to the high hardness of the lion's share of the initial time to absorb and this happening until that happens some of concrete have been too تغييرشکلهاي and antefa can be removed from haiz where sections steel sheet also buckling. For this reason, do not place the field diameter of a stretching.Comparative figures in the side تغييرمکان maximum has been shown. These charts as expected, increasing the hardness in the sample increased with the distance between the brshgirha to a good level.As comparative graphs can be significant energy, the maximum energy absorption reduction corresponds to a change in the thickness of the steel sheet (reduced) that shows the effect of steel plate system in the form of utmost ability. And in the case that a change in the thickness of the concrete cover has been achieved (3 cm in thickness reduction of concrete cover) the effect of chndani on the uptake of energy and in other words the effect of chndani in the form of system v.
