Abstract
This invention refers to a structural system for floor and roof construction, based on a parallel arrangement of a set of composite pre-tensioned girders to provide support to a deck formed by layers of any given material. The composite girders are components formed by lengths of bamboo culms, steel components and fillings of mortar or other materials, arranged in such way that a maximum mechanical efficiency is obtained.
Claims31
A slab system comprising:
- a deck comprising one or more layers which form a structural diaphragm and/or a top finishing layer and a bottom finishing layer;
- and
- a plurality of pre-tensioned composite girders installed in a parallel arrangement to support the deck, the pre-tensioned composite girders made with a length of bamboo culm and a profile of greater length.
A pre-tensioning process for bamboo characterized in that a bamboo culm is selected based on criteria that takes into consideration ranges of age, cracks, taper and internodal length to produce a composite girder made by selected bamboo with cracks not exceeding from 20% to 30% of a length of the bamboo culm, provided cracks are not located at a neutral axis of a composite girder.
