Processo construtivo de estrutura gridshell pós-formada com uso de pinus

Abstract

The gridshell structures are formed by lamellar or tubular grid-shaped elements, being designed and constructed in different materials, such as steel, wood and composites. The differential is the use of a reduced amount of material in buildings with large internal space, without the need for pillars along the span. Thus, works of great extensions like pavilions, hangars and sheds can be executed in a short time. This research analyses and demonstrates the gridshells assembly process, details the existing construction methods and the types of connections used to join the pieces that form the set, giving priority to studies that highlight the use of wood as a raw material. A Systematic Mapping Study was also carried out with an emphasis on the scientific papers published in the area. This survey helped to chart the world's gridshell studies all over the world, identifying the countries and institutions that more contributed to spread articles in a 35-year window of time. The work also includes: (i) the listing of some existing constructive achievements; (ii) the design process and the projected structure modelling; (iii) the execution of small scale and full-size mock-ups; (iv) the theoretical and experimental evaluation of project parts; (v) the fabrication of the lamellar elements; (vi) the description of the construction of a grid called Dunas Gridshell in real scale using the pine woods (genus Pinus), showing its technical details, execution time and cost.
