Q2. A reinforced-concrete wall will be formed using job-built panels. The form panels will have sheathing that is 0.5" thick supported by 2x4s (spaced 12" on center) that are supported by double 2x6 wales (spaced 12" on center), all Douglas-Fir-Larch No. 2. Assume the lumber has minimal defects and will be used only twice. The wood is stored in a warehouse, waiting for installation. What values for allowable bending stress, allowable shear stress, and modulus of elasticity should be used to design the form panel studs?

please help me with question

PROBLEM:1 A) Mention the different types of wood which are used in the construction industry. B) Explain the framing system of a small house structure and mention the members designation i.e. stud, etc. C) What are the moisture limits for the wood members?

A fully composite section that is comprised of an A992 W16x31 with a 5-inch, (f'c= 4 ksi) slab on top of it. The beam span is 30' and the spacing of the beams is 5-foot. All the shear studs to make the composite beam were completely forgotten to be installed by the contractor. Assume that the friction between the slab and the steel beam is enough to provide continuous lateral support to the compression flange of the steel beam but provides no composite action between the concrete and the steel. What is the LRFD moment capacity (4bMn) of this badly built attempt at a 'composite' beam, Hint; The flexural strength of the unreinforced concrete slab is 7.5*(f'c)^0.5 Also, the fundamental flexural equation is MC/I. Show all work.
