✦ Synopsis

A procedure has been presented in this paper to identify the structural parameters, viz. mass and sti ness matrices, from modal test data for multistorey shear buildings. The ΓΏrst two orders of modal data have been used by other researchers to estimate the global matrices where they depend only on measurable points which are less than the total number of structural degrees of freedom. The above method has been reΓΏned here by using Holzer criteria along with other numerical methods to estimate the global mass and sti ness matrices of the structure. This shows the methodology to be more e cient and accurate. The reliability of the procedure has been shown by examples of multistorey buildings.

This paper deals with the important question of structural safety after extreme loadings like an earthquake. The structure investigated here is the so-called 'Steelquake' benchmark structure, a two-storey building which was subjected by an artificial seismic loading causing cracks at three locations
