What is it about?

The goal behind this research is to highlight on structural system using composite steel plate shear wall, this approach is widely used in many countries, due to its desired features. Composite steel plate shear wall are often considered essential in design of building to resist seismic action. This paper discuss the effect of concrete strength on behavior of CSPW, for this objective one story one bay model with different compressive strength (25, 28 , 45, 50, 55, 65)MPa ,this model formed by finite element code which is advanced by university of Amirkabir. The accuracy of the representation of the model by numerical analysis, numerical result contrast with valid experiment which explain suitable agreement. Result show increasing the compressive strength would advance the cycle behavior. By contrast the result in elastic region, it was seen initial stiffness is not enhance by varying the compressive strength.

Why is it important?

To construct validity of analyzed model of composite shear wall specimen (1000*2000 mm) on which the thickness of steel plate and concrete cover is 3 and 50 mm respectively, and height overall ratio to the span is 1/2. Applied under cyclic loading and its deformation-load diagram drown and compared to the analyzed results of similar numerical model.

Perspectives

Variations in the value of compressive strength of concrete wall can increase stiffness and ductility .With respect to the analysis, max ratio of enhance for stiffness and ductility obtained for composite steel plate shear wall as 1:3 scales equivalent 14% ,47% with respect to compressive strength (65 MPa) of concrete wall, in other meaning when compressive strength is large, the CSPW exhibits plump hysteretic curve under cyclic loading, meaning better behavior of all model.
