โฆ Synopsis
Abstract
This paper reviews briefly traditional rehabilitation methods and provides a detailed discussion of design issues along with the advantages and the disadvantages of innovative strategies for seismic retrofitting of steel and composite structures. Special emphasis is placed on base isolation and supplemental damping devices. The viability and costโeffectiveness of these strategies are assessed on the basis of multiple limit states within the framework of performanceโbased design. A number of parameters which govern the selection of the intervention devices are investigated.

## Abstract Novel metals such as aluminium alloys, stainless steels and shape memory alloys can be used for the retrofitting of steel buildings in seismic areas. Therefore, it is useful to investigate their mechanical and physical properties along with the key issues of the material modelling. The
The nonlinear seismic responses of steel frames with fully restrained, partially restrained and composite connections are evaluated and compared in terms of the maximum interstory and maximum top lateral displacements. Steel frames are usually analyzed assuming all the
## Abstract There is a worldwide trend for modern design specifications to depart from prescriptive methods and to move towards performanceโbased design approaches. The gradual shift towards performanceโbased design increases the need to have efficient and robust direct analysis methods to assess t
