Seismic retrofit of stone walls with timber panels and steel wire ropes

Light Steel-Timber Frame with Composite and Plaster Bracing Panels

The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab. Steel brackets are used as foundation and floor connections. Experimental cycl...

Seismic Retrofit of Bridge Steel Truss Pier Anchorage Connections

In assessments of the seismic adequacy of existing steel bridges, the steel-to-concrete anchorage connections typically found at the base of steel truss piers can be potentially vulnerable, having little to no ductility and inadequate strength to resist seismic demands. Many other non-ductile failure locations may also exist along the seismic load path. Failure would result in unacceptable perf...

Fe Analysis of Steel Links for Seismic Resistant Timber Frames

Performance Based Seismic Rehabilitation of Steel Structures with Different Types of Shear Walls

Seismic rehabilitation provides existing buildings with more resistance to seismic activity, ground motion, or geotechnical failure due to earthquakes. Performance-based rehabilitation is a general concept through which the retrofitting criteria are defined regarding to performance objectives when the structural and nonstructural members are subject to different levels of earthquake hazards. In...

Seismic Behavior of Intermediate Beams in Steel Plate Shear Walls

This paper presents some preliminary results of an ongoing research whose objective is to investigate the seismic behavior of intermediate beams (i.e., the beams other than those at the roof and foundation levels) in multi-story steel plate shear walls (SPSWs). Of primary interest is the determination of the strength level needed to avoid the formation of in-span plastic hinges, a relevant prac...
