A floor system is to consist of beams, girders, and a slab; a partial floor plan is shown below. Service loads are to be 45 psf dead load (does not include the weight of the floor system) and 160 psf live load. Use fe' = 4,000 psi, and fy = 60,000 psi. Design the continuous beam along column line 2. Be sure to include complete design sketches. 2 3 11 -32-0- B 11 --+1- -32-0 Typical Partial Floor Plan 16'-0" 16-0* (typ.) Beam Girder

Please Answer fast as u know... im needed in 15-30 minutes thank u... So please

Wood planks are used on each working level. The deck width/bearer span is 5 ft.. The bearers and posts are standard pipe and the pipe material is A36 steel with a yield stress of 36,000 psi and modulus of elasticity of 29,000,000 psi. Bearers are to be located at a vertical spacing of 10 ft (largest, lowest post height). Posts are to be 7 ft oc (plank length) parallel to the building wall and 5 ft apart (bearer length) perpendicular to the building wall. There are four working levels and the anticipated scaffold loading will be med duty. A. Assuming the ultimate bending strength of the planks is 3,800 psi (apply a 4:1 F.O.S.), determine the required minimum plank thickness to the nearest 100th.  B. Based on the bearer material provided, what is the minimum pipe size that can be safely used? See Appendix 2 in your textbook for steel pipe properties.  C. Based on the post material provided, can a 2” standard pipe be used safely? Be sure it satisfies buckling stress conditions only.
