More optimal seismic design of highrise structures using
nonlinear analysis techniques

Thornton Tomasetti, New York, NY, USA
ABSTRACT: It is a well-known feature of dynamic response of highrise structures that their seismic response,
including the distribution of strength and deformation requirements, is very different from low-rise structures.
Most design codes allow for or require the use of modal analysis techniques to allow the design to capture the
effects of higher modes present in the response. However, buildings are typically designed to undergo significant
nonlinearity during ...
