Jafari et alii, Frattura ed Integrità Strutturale, 50 (2019) 209-230; DOI: 10.3221/IGF-ESIS.50.18 211 This research contains various models such as shear wall with openings close to the beam/column, horizontal/vertical openings and distributing opening. Push over method was employed in order to obtain shear wall performance (capacity, stress and displacement), then ANN and fitness function tools were employed to obtain neural network models for shear wall [16]. Applying additives for conventional concrete has been the subject of much research. The performance of sandwich panel has been studied in different experimental previous research, but there are few numerical investigations on improving the sandwich panel behavior under the seismic load and how changing the shotcrete Young's modulus affects the behavior of the building. The present research studies the effects of the Young's modulus on performance of a panel against earthquake load in a two-story building. Therefore, first, using the data from the literature on shotcrete with Silica additive, the range of Young's modulus has been chosen based on this research, thus, the compressive strength, Young's modulus and the density of the shotcrete are obtained and also, the properties of other materials like steel wires, insulating panel and concrete layers are introduced into the soft-ware. After this process, the panel performance against loading is evaluated by changing the amount of Young's modulus in different panels and the results were analyzed. Besides, the effects of increasing the panels' number and height on the frame performance are another aim of the present study. Using ANFIS to predict the numerical FEM result of sandwich panel is another new issue, which will be discussed in the concluding part of this study. Applying ANFIS as the neural network to interpret ABAQUS results and investigate the capability of this method to predict FEM out-puts are the ultimate goals. M ETHOD his research investigates the effects of additive on shotcrete concrete sandwich panel (that leads to an increase in concrete Young's modulus) and sandwich panels performance in a large (building frame) and small area (concrete layer, sandwich panel), respectively. Here, for obtaining the Young's modulus, the data reported by Wolsiefer [2] and Rezayifar was used. For this purpose, the Young's modulus between (15 GPa to 30 GPa) are considered and different points in different areas of the frame are chosen. The software ABAQUS is used as the analysis tool [17]. A tie is used to paste the insulating layers to concrete according to the proposal of composite material; moreover, a nonlinear dynamic analysis is applied. Electro acceleration is imputed in the support place in X and Y direction. On the left side of the frame, two oblique panels and on the right side, three panels are applied. The panel making procedure by ABAQUS was proposed by Gara in 2012 and panel-making processes are similar [8, 18]. Wire mesh is embedded in concrete layers and the walls are connected to the column. Fig. 1 presents the schematics of the modeled panel. Figure 1 : Schematics of the model in ABAQUS The acceleration and displacement are calculated and depicted in the diagram for all the mentioned concretes. The present research has the following main steps:  An experimental and numerical paper from science direct journal has been chosen as the reference for verification. This paper is an FEM and experimental study on sandwich panel for earthquake load. Therefore, T
