Dynamical similarity of multi-block catenary arches and rocking blocks subjected to horizontal base excitation

Abstract In this paper, the dynamical similarity of multi-block catenary arches and columns is discussed, which can be used for simplified design rocking arches. The basic hypothesis that dynamic response similar when shape arch follows thrust line, i.e. it a arch. It validated numerically responses slender are safe reliable approximations those not then overturning acceleration (response) spectra rigid, monolithic blocks directly applied based on two parameters, limit peak ground (under structure will move at all) frequency parameter (defined by Housner rigid blocks).
