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...

Previous studies have underlined the importance of establishing a database high-fidelity benchmark experimental test results under random loading histories such as earthquake excitations for both existing structural systems well newly proposed ones. Such are useful understanding limitations previously developed numerical models, proposing new models more recently systems, better assessing ultra...

Timber platform-frame shear walls are characterized by high ductility and diffuse energy dissipation but limited in-plane shear resistance. A novel lightweight constructive system composed of steel columns braced with oriented strand board (OSB) panels was conceived and tested. Preliminary laboratory tests were performed to study the OSB-to-column connections with self-drilling screws. Then, th...

Origami-inspired foldable structures have seen much recent interest for applications in which transportability or rapid construction are primary design drivers, for example emergency shelters and temporary staging structures. This paper proposes a new type of a structural module that can be manually folded from flat steel sheet into a novel self-braced triangular structural section. Simple geom...

in this paper, the problem of layout optimization for x-bracing of steel frames is studied using the ant system (as). a new design method is employed to share the gravity and the lateral loads between the main frame and the bracings according to the requirements of the ibc2006 code. an algorithm is developed which is called optimum steel designer (osd). an optimization method based on an approx...

Seismic excitation can cause significant energy to be released within structures. By using special devices, this consumed and dissipated without deforming structural members significantly. Due this, damage is minimized, casualties are prevented during earthquakes, structures extended in their useful life. Over the past five decades, it has been widely acknowledged that steel yielding dampers am...
