A deterministic design procedure for multi-storey frames that are exposed to random seismic excitations
The concepts of capacity design philosophy, which aims to ensure a desirable sequence in the plastification of ductile frames during severe seismic excitation, are introduced. In the establishment of desirable strength hierarchies the relationship between beam load inputs and ideal column strengths are examined in detail. Simple procedures, that recognise relative strength values and general characteristics of dynamic behaviour, are proposed for the evaluation of moments, axial and shear forces for columns of frames. The proposals intend to ensure a high degree of protection against premature damage to columns, and to elimate the possibility of concentrated energy dissipation in storey mechanisms in frames that may be subjected to unidirectional earthquake attack or to concurrent orthogonal seismic excitations.
