Problem 3: The accompanying illustration shows the arrangement of beams and girders that are used to support a 6-in reinforced concrete floor for a small industrial building. Design the beams and girders assuming that they are simply supported. Assume full lateral support of the compression flange and a live load of 120 psf. Concrete unit weight is 150 lb/ft' and Fy 50 ksi. %3D -エ エーT Column Girder Beam Note: Floor continues on all sides *-エ 3 at 15 ft = 45 ft y SE

Need right complete solution

Show step by step, please  Determine the factored uniform line load, wu, acting on girder HK.

Consider the following framing plan below. Squares labeled A through L are columns. All girders have rectangular sections with width 300 mm and depth 600 mm. Slab thickness is 125 mm. Superimposed dead load for the entire floor is 2.95 kPa and live load for the entire floor is 4.8 kPa. For self-weight of the floor system, use unit weight of RC of 23.6 kN/m3. a. Considering continuous girder DEF, determine the maximum factored positive & negative moments Mu (+) & Mu (-), as well as the factored shear Vu that should be used for the design of the said girder. Use ACI moment & shear coefficients to draw the factored shear & moment diagram of the said girder.

Problem: Using WSD & USD, design the midspan reinforcement of stringer (B-3) for the second floor of a 3-storey residential building shown below. Use 20.7MPa compressive strength of concrete @ 28-days and grade 40 reinforcing bars. Use Ye= 24.5 KN/m³. Design the stringer as rectangular beam. Assume simply supported. 450mm 250mm 250mm, 450mm Superimposed Deadloads = 2.70 KPa Stirrups - 10mm Main bar = 25mm 350mm B-4 STAIRWELL B-1 250x400mm S-3 B-3 250x400mm S-4 3096 mm 350mm B-4 350mml Stringer Section 2096 mm 3596 mm 2096 mm 700mm

A doubly reinforced beam, which have a base of 310 mm, and an effective depth of 410 mm, is reinforced with steel area of 2063 sq. mm at the bottom, and 1232 sq. mm on the top. Take d' = 70 mm, fc' = 21 MPa, and fy = 345 MPa. b) What is the value of fs' (actual stress of the compression bars) %3D None of the Choices 216.070 MPa O 188.266 MPa 241.923 MPa 229.239 MPa 202.413 MPa

Please correct answer

What is the ultimate uniaxial load capacity of the given column section, according to the design strengths of the materials? Concrete is C30, longitu- dinal steel bars and ties are B420C. Longitudinal bars are o14, ties are o10. b= 300 mm, h= 400mm. The column will be produced on site with adequate quality control. %3D h 1357 kN b) 750 kN 2490 kN d) 1150 kN 1470 kN Leave blank
