Description

  • A completely new type of steel connection according to claim 1 is invented. It is the jacket-plate-connection system using 3-dimensional connection plates and tension rods to achieve exceptional structural performance that is superior to any conventional connections, either bolted or welded, that use 2-dimensial (i.e. flat) gusset plate and/or side plates. The merits of the novel connections include higher strength and ductility, stronger yet simpler connections, higher quality, small components for easy storage and transportation. Additionally, they eliminate all of the inherent drawbacks and problems of conventional bolted and/or welded connections. The present invention is a versatile connections system that can be use in any steel frames and trusses that is made of W-sections. It basically redefines concept of structural steel connections, and has the potential to reform the current market of steel construction. The economical and social impact will be significant.
  • There are three very unique features of this connection system: (1) For the first time in the industry, this invention introduces three dimensional connection plates in a systematical way. It addresses all possible connection type in a simple and consistent manner. (2) This invention uses through the depth steel rods, coupled with typical web stiffeners to transfer shear and bending moment across the connection. This type of shear transfer mechanism is similar to stirrups in reinforced concrete beams and columns. Although being widely used in reinforced concrete structures for many years, it is first time that the mechanism being ever utilized in steel frames and trusses; (3) all components and parts can be prefabricated in shop, and conveniently bolted together at field. With this invention, it becomes practical to build all steel frames without field welding, including the following popular high performance seismic steel frames: special moment resisting frame (SMRF), eccentrically braced frame (EBF), and special concentrically braced frames (SCBF). (Note that there are no all-bolted SMRF, EBF and SCBR at the current market, due to the fact that traditional bolted connections cannot achieve the required strengthen and ductility at practical costs. In other words, these connections are all or partially welded connections.)
  • WO01/46531 discloses a building frame resistant to earthquakes, gale-force wind loads, fire, insects and rot includes a peripheral frame wall constructed of rectangular steel tubing. Side wall frame modules bolted together along adjacent edges, and end wall modules bolted together along adjacent edges and to the ends of the connected side wall modules form the peripheral frame wall. Diagonal bracing is built into selected side and end wall modules as required for the desired degree of wind resistance. Trusses made of various size tube such as 2X3 inch rectangular steel tubing for supporting a roof, including a hip roof, on the peripheral wall, are assembled and welded in a welding shop and the prefabricated trusses and wall modules are trucked to the building site. Multiple stories may be erected and fastened together by anchor brackets arranged bottom-to-bottom above and below the second and higher floors. The building frame is secured to a foundation by attaching the anchor brackets to anchor bolts set in the foundation.
  • US 3414300 discloses a steel connection having the features of the preamble of claim 1. The connection has mitered abutting ends of angularly disposed pair of timbers have a metal plate there between. Common side faces and in hand held edits of the timbers adjacent to the angle are embraced by a U shaped angular metallic channel to which the metal plate is intricately attached. The shaped channel is secured to the timbers, and the timbers are secured together into a rigid structure by plural fasteners passing from external of the channel into the timber structure.
