Performance Based Evaluation of Buildings Nonlinear Pushover and Time History Analisys

The Holmes Consulting Group philosophy of innovation in structural design has by necessity

required innovation in structural analysis. Projects such as Union House base isolation,

Parliament Strengthening, Coopers Lybrand and the Museum of New Zealand, Te Papa

Tongarewa, were designed using non-linear analysis techniques as part of the evaluation

procedure. Since 1991, this type of analysis has been performed in-house using proprietary

software.

In the last few years (1996 onwards), performance based design has become favored for the

evaluation and strengthening of existing buildings to resist earthquake loads. This type of design

uses similar analysis techniques to those developed by HCG and so the in-house software has

been adapted to incorporate the requirements of performance based evaluation. This manual

describes the implementation of these procedures:
