Full Characterization of Calycophyllum Multiflorum Wood Specie

Abstract

Wood is a material that for years has been used by man for a variety of purposes, particularly in rural and civil constructions and furniture industry. The possibility of shortages of some wood species, the characterization of other unfamiliar species is an alternative source for use in civil and rural construction. This study aimed to determine, with the aid of Brazilian standard NBR 7190, physical and mechanical properties of Castelo (Calycophyllum multiflorum) wood specie. Twelve determinations were obtained by property, totaling 204 experimental values. In the characterization of wood, regression models were used to estimate the values of timber strength and stiffness as a function of apparent density, being density the physical property more simple to be obtained. The results of mechanical properties showed consistent with the performance of other species used in construction, which highlights the potential use of the Castelo wood in structural design. Regression models, apparent density was considered significant in the estimation of only 4 among the 14 properties for wood strength and stiffness.

Physical and Mechanical Characterization of Copaifera sp. Wood Specie

“…Nowadays it is used in construction, paper manufacture, musical instruments, sports equipment, and wood panels. The use of wood in a large range of view implies the knowledge of its properties (physical, chemical, mechanical and anatomical) for a rational use of this material, which is a natural resource, meeting the requirements that the current environmental appeal of products and services provided by man [1][2][3].…”

Timber Use in Truss Structures for Roof (“Howe” Type – 8 to 18 Meters)

“…As a material, it presents a wide application variety and, particularly, in structures, can be used for roofs (residential, commercial, and industrial), works of art (bridges, footbridges) and storage (silo) [1].…”

“…In general, they are used in civil construction, mainly in panels, formwork and reinforced concrete structures shoring and lattice structures for roofing [1].…”

Technical Feasibility Study for the Use of Alternative Timber in Latticework for Roofing with Spans between 16 and 26 Meters

“…However, even though there are standards, wood is still used improperly, such as temporary use for shoring of slabs, sheds, scaffolding, among others. In this way, it causes a great waste and discards a material that has great potential in the civil construction [5].…”
