Abstract (EN): This study focuses on preventing collisions between structures during seismic excitation based on gap size. Several approximated equations in order to estimate separation distance between buildings are collected and evaluated to measure gap size in order to avoid impact between them when large lateral displacements occurred due to earthquake. Artificial neural networks are utilized to estimate the required distance between structures. The majority of building codes suggest separation distances based on maximum lateral displacements of each building or height of buildings in order to provide safety gap size between them. Subsequently, researchers have proposed several equations to predict the critical distance. In current study, some MDOF models are equivalently modelled and optimum gap size between buildings is approximately estimated and finally a new equation for separation distance is suggested and the accuracy of formula is numerically investigated.
