Benefits of technology

This patent describes a connection between two structures, like a bridge, that is designed to be stable and reliable under regular service conditions. Additionally, the connection is designed to handle temporary separated movements caused by events like earthquikes or hurricanes. The goal is to minimize damage to other parts and keep the overall structure intact.

Problems solved by technology

On the other hand, the layout of tendon-fasteners system requires relatively large space for the device.

Embodiment Construction

[0056]The first embodiment is based on the concept of “V-sliding” in FIG. 9, which employs at least one pair of V-shape sliding-contact surfaces to establish the connection between super- and sub-structure of a large-scaled civil engineering structural system, allowing a temporally relative sliding when one of sub or superstructure is struck by single or a spectrum of external impacts, so as to protect another part from the inertia force flow induced by the impacts. Once such a contacted surface-pair tends to slide, the weight of carried superstructure introduces lateral force toward the opposite direction of the sliding, which, in conjunction with friction, assures the bearing is solid connection during regular services or when inertia-induced lateral force is lower than the resultant of static friction and superstructure's weight-induced lateral resistance. The latter is determined by the slope angle of the V that is designed according to FIG. 1 or 2, which is also the driving for...

Abstract

A class of bearings, each of them can be used as a connector to connect two parts in a structural system and as a supporter to transfer loads from one part to another, for examples, gravity of a superstructure to a substructure in a bridge or a building, or that of a machine to its foundation. While performing load transmission, it is able to reduce the transmission of transient vibrations between connected two structural parts and preserve the integrity of entire structural system; for examples, to protect a bridge's structural integrity when either an earthquake strikes its pier and foundation or a tsunami hits its superstructure or both occur simultaneously.

Description

FIELD OF INVENTION[0001]The present invention discloses a class of apparatuses. A said apparatus is used as a structural component in a large-scaled civil engineering system such as a building, a bridge, or a machine and its foundation, which has at least the following three functions: being a support to bear the weight of a part of said system, connecting different parts of the system to assure structural integrity, and transferring designed force-flows other than gravity between connected parts while damping out or isolating undesired vibrations.[0002]For said engineering system like a bridge or a building, it generally can be divided into two parts: the superstructure such as a bridge's spans and deck that carries designed live loads; and the substructure that includes the bridge's piers, footing, and foundation, which supports carried superstructure. Wherein said bearing is a structural component that connects super and substructure, transferring carried superstructure's weight ...
