Composite Steel Plate Shear Walls (CSPSW) are a developed type of steel shear walls that can be used in two ways to form the buckling due to the buckling in the steel sheet in these walls. One method is to use metal hardeners and the other is to use a concrete cover that is attached to the steel sheet through cutters. The second type is known as composite shear wall. In steel shear wall, the floor shear is transferred using the tensile field of the steel plate and after buckling due to diagonal pressure. In a composite cutting wall, the concrete wall preserves the steel plate and prevents it from buckling before yielding to pressure. As a result, the steel plate resists the shear force of the floor due to shear yield. The shear yield capacity of a metal plate is clearly greater than the capacity it seeks to obtain with the help of a diagonal tensile field. In addition, the compacted concrete wall provides insulation against sound and temperature, and makes steel shear walls resistant and fire-retardant for steel sheets. However, due to architectural and installation reasons, these walls need to be opened. So with modeling as well as recommendations and criteria related to composite shear walls from different regulations to make a relationship for the case that we want to design the wall with opening with the given relations without opening, we have finally done the process of seismic design In composite shear wall systems, along with some design recommendations, it is stated about the design of composite shear wall components.

Due to the corrosion problem in reinforced concrete structures, the use of fiber-reinforced polymer (FRP) bars may be preferred in place of traditional reinforcing steel. FRP bars are used in concrete constructions to boost the strength of structural elements and retain their longevity. In this study, the axial load carrying capacity (ALCC) of the FRP-reinforced concrete columns has been evaluated using analytical, as well as machine learning, models. A total of fourteen popular analytical models and one proposed machine learning-based model were used to estimate the ALCC of the concrete columns. The proposed machine learning model is based on an artificial neural network (ANN) method. The performance of the ANN, as well as the analytical models, are assessed using six different performance indices. The R-value of the developed ANN model is 0.9758, followed by an NS value of 0.9513. It has been found that the mean absolute percentage error of the best-fitted analytical model is 328.71% higher than the ANN model, and the root-mean-square error value of the best-fitted analytical model is 211.97% higher than the ANN model. The evaluated data demonstrate that the proposed ANN model performs better than the other analytical models. The developed model is quick and easy-to-use to estimate the axial capacity of the FRP-reinforced concrete columns.
