System to dissipate seismic energy in buildings.

摘要

The invention relates to a system for dissipating seismic energy in constructions, formed by two or more sections, tubes or plates disposed with the axes thereof in parallel (1, 2) and connected using one or more energy-dissipating elements (3) disposed such that the axes thereof are perpendicular to the axes of the sections, tubes or plates. The energy-dissipating elements can take the form of sections, preferably having an I- or H-shaped cross-section, which are made to function very differently to normal when used in earthquake-resistant structures, the core of the I- or H-section being subjected to plastic bending deformations in a plane perpendicular to the plane of the core, said cores being maintained in elastic state. Under axial loading, the invention dissipates energy in a stable manner without buckling.
