Building has an important function, namely as a place for humans to carry out various activities in the form of religious activities, social activities, business activities, business activities and other activities. In many aspects the shape of the building is an important consideration when planning the building to be made. The building model used is divided into three main models of the most commonly applied buildings, namely: the box building model, the L model and the U model. The 3D STERA program functions as auxiliary software to determine the strength values of the structure by giving earthquake loads using the historical time on each structure model. The El Centro earthquake and the Kobe earthquake were the earthquakes that were tested in this structural model because they had the greatest damage to the history of the earthquake caused by the earthquake. The things that are assessed on the structural model tested are in the form of structural rigidity, the greatest displacement in the structure, the relationship between the structure and the maximum load experienced by the structure and energy hysteresis experienced by the structure, so that it can finally be concluded load that works. The results of the study show that the U model has the largest stiffness value with a stiffness increase of 7.43% to the box model and 3.01% to the L. model.
