Abstract:
A seismic isolation system for underground structures comprises a periodic foundation and periodic arrays of piles in the soil or periodic piles that surround the underground structure. The periodic foundation may be a foundation of periodic materials. The periodic piles can substantially reduce the incoming seismic waves from the lateral direction. The periodic piles may be vertically arranged layers of periodic materials. The combination of the periodic foundation and periodic piles can result in total isolation for the underground structure. This total isolation may be of particular interest for underground facilities, such as underground nuclear power plants and structures with basements.
Abstract:
Composite foundation for attenuating the seismic action, for building constructions and the like, characterized in that it comprises several concrete slabs superimposed on each other, wherein said concrete slabs are provided with suitably arranged cavities inside which a metal mass (2) free to oscillate is placed.
Abstract:
A vibration damper device (l) for prefabricated warehouses (100) and similar building structures comprising: a rigid bracket (2) which is provided with a substantially flat side shoulder (2a) on which a substantially rectilinear longitudinal groove or slit (3) is realized, and which is structured so as to be anchored in a rigid manner on the body of the lintel (103) or of the pillar (101), next to the covering beam (104) or next to the plug panel (105), so as to arrange said side shoulder (2a) facing the lateral side of the covering beam (104) or facing the surface of the plug panel (105), with the longitudinal groove or slit (3) locally substantially parallel to the longitudinal axis (L) of the covering beam (104) or to the longitudinal axis (F) of the plug panel (105); a movable slider (4) which slidably engages the longitudinal groove or slit (3) provided on said side shoulder (2a), and is structured so as to be anchored in a rigid manner to the body of the covering beam (104) or to the body of the plug panel (105),· and a deformable connecting member (6) with elastoplastic behavior, which is structured so as to connect the movable slider (4) in a rigid manner to the bracket (2), and to deform in elastoplastic manner as a result of any displacement of the movable slider (4) along the longitudinal groove or slit (3) of the bracket (2).
Abstract:
The invention relates to the use of at least one intermediate layer (2) disposed in or under a building (1), said intermediate layer comprising or being made of at least one elastomer for reducing, in particular for preventing, earthquake-related damages to the building (1).
Abstract:
The description herein refers to a modular construction system (1) used for reinforcing all shapes of foundation, pillars, isolated footings and anti-seismic separators intended for transpiring, heat-insulation variable-geometry formwork, including at least one guide plane (10) for the vertical elements of such reinforcement and at least one supporting bracket (30) for such plane (10), said bracket (30) being suited to make it possible to install such guide plane (10) relative to such transpiring, "disposable" heat-insulation formwork.
Abstract:
Verwendung von zumindest einer, in einem oder unter einem Gebäude (1) angeordneten Zwischenlage (2) mit oder aus zumindest einem Elastomer zur Verminderung, insbesondere zur Vermeidung, von durch Erdbeben verursachten Schäden am Gebäude (1).
Abstract:
A method of supporting a building includes securing one end of a support stand having a telescopic structure to a movable concrete footer. The support stand may have another end with a support assembly mounted to the telescopic structure. The method includes supporting the building with support assembly of the support stand. A support stand for a supporting a building includes tubular structure with a telescopic adjustment portion for adjusting a height of a building. A support assembly mounted to the telescopic adjustment portion, the support assembly having a support plate with a plurality of apertures in a shape configured for retaining a threaded portion of a fastening member in a stationary position while a threaded nut is rotated on the threaded portion.
Abstract:
