What are the properties of resistance and stiffness of wood?
A - Obtained by Wood Characterization Tests (NBR 7190: Parts 2, 3, and 4)
B - By NBR 7190 Standard → according to the resistance class of the species (TAB 2 and 3, pg 12 of NBR 7190 (2022))
B.1 - Complete Characterization
B.2 - Simplified Characterization
B.3 - Minimum Characterization
C - Characterization of Wood Stiffness
C.1 - Complete Characterization
C.2 - Simplified Characterization
D - Calculation of the Resistance
E - Calculation of the Design Resistance
A - The properties of resistance and stiffness of wood are obtained by tests of characterization of the wood according to NBR 7190.
B - The NBR 7190 standard establishes the properties of resistance and stiffness of wood according to the resistance class of the species.
C - The characterization of wood stiffness is identified by the letter E accompanied by indices that identify the direction to which the property applies.
D - The calculation of the resistance of wood takes into account the characteristic value of the resistance and the modification coefficient.
E - The calculation of the design resistance of wood takes into account the ratio between the applied load and the resistance of the wood.
