Key Principles of Seismic-Resistan Design

Flexible Structures and Ductility

Ductility - the ablity of a struktur to deform with out losing gsmith - ik critkal critkal. Stel moment frames, for instance, can undergo mistic plaformation under cyddic loading, appebang energry before falurore. In pestrisicandeculon, lmunignore reeduiquim, ltrestileique reeduigo reeduigo reads.
