In this research, a simple, efficient and expeditious method for nonlinear analysis of reinforced concrete and steel structural members, based on fiber method concepts is introduced. One of the considerable advantages of the mentioned method, is its high speed in nonlinear analysis of structural members which would make it distinctive from the others. For instance, analysis of high–rise buildings utilizing 3D elements, besides the complexity for the reason of high degrees of freedom, requires spending far greater amount of time and also might be impossible in some cases. In this method each structural member such as beam or column is considered as a beam–column element with two nodes and three degrees of freedom in each node and corresponding stiffness matrix based on reperesented equations is assigned to this element. Finally to affirm accuracy of this method, a cyclic nonlinear statically analysis on a concrete frame is accomplished to compare with experimental results. A time–history analysis also is accomplished on a steel frame and will be checked with Huu–Tai Thai‟s research. The opensees software is used to model the discussed portal frames.<\div>

The use of common reinforced concrete shear walls in high rise buildings is sometimes limited because of the large amount of reinforcement localized at the end ofthe element. A good alternative solution in avoiding this disadvantage is to use composite steel reinforced concrete shear walls (CSRCW) with steel encased profiles. This solutionused for high rise buildings, offers to designers lateral stiffness, shear capacity and high bending resisting moment of the structural walls with even better behavior in cyclic loads like earthquake loading. This study consist of numerical analysis of 1:3 scale ofcomposite shear wall elements. The aim of this study is to introduce a time–saving and precise method, called fiber element method, for analyzing the walls and to verify thenonlinear behavior of a kind of CSRCWs with three different steel shape encased profiles and a common type of CSRW, then comparing them with each other. To establish the accuracy of the analytical model and experimental results for load–displacement,hysteretic responses are studied for cyclic loading. The OpenSees software is used for modelling the discussed shear walls.<\div>
