The shotcrete and the change in its Young's modulus affected the building behavior in a manner that great changes were observed in the displacement and acceleration of the panels, frames, and concrete layers. Investigating the 63 day, 7 day and 24 hour concretes and comparing the results show that the age of the concrete can affect the building behavior. In all cases, the wires showed good reaction against the earthquake load and no one was separated from the concrete. Using the diagrams of force, displacement, acceleration and hysteresis cycle, the present research investigated the panel behavior. By changing sandwich panels' number on the two sides of the frame, this study evaluated the frame maximum deflection under the Elcentro-1940 record. One of the issues of the research was the high simulation time, due to choosing solid elements for all the components (except for the wires). Using ANFIS to elaborate and predict the result of FEM is an innovation of this paper for discussing the building performance. The computations of the application of sandwich panels in the frame instead of brick material demonstrated that the building weight decreases according to Tab. 3.
