1. The formula should be used in calculating the strength of pression timber member.
where: A is the gross section area of the member. Is this true or false? Why?
describe the load bearing systems of a light wood frame structure.(hint: considering the vertical loads and the horizontal loads to the structure respectively)
4 or more factors that affect the design strength of timber.
4、What do you need to keep in mind when you design a connection of timber construction?
the following two cases of loading. Both cases are made with solid sawn wood product. Which of the following statement is true?
A. The modulus of rupture value obtained from case 2 is greater than case 1.
B. The modulus of rupture value obtained from case 1 is greater than case 2.
C. The modulus of rupture values obtained from both cases are the same.
is the bending strength of structural timber higher than the tension parallel to grain strength? Please mark, which one of the following answers is correct?
A
Because beams in bending fail on pression side and not on the tension side
B
Because the tension stressed volume of a member under a tension load is much larger than the tension stressed volume of a beam in bending.
C
Because the bending strengt
