Abstract
Over the past twenty years, many types of joints have been developed to connect structural elements and all of them have been suited to their particular construction requirements. Mero; Unistrut; Triodetic, Tuball joint; Octatube are some examples of joints that have been widely applied in the construction of tubular single-layer and even multiple-layer domes all over the world. However, most of the joint hardware produced so far has been fabricated utilizing casted steel as a single material, which is expensive in Mexico. The hybrid joint herein introduced is composed of three materials: steel; high strength plastic and rubber.In 2002, the author won a design competition for a crystal dome design that should have fulfilled four major requirements: safety, economy, lightness and aesthetics, and he was commissioned to build the aforementioned dome in Queretaro city, Mexico that covered the atrium of 'Boulevares Shopping Plaza' with plan dimensions 20.00 m X 30.00 m. and 3.00 m height.
