In the context of beam shear, given the beam size, various loading, concrete and steelstrengths, span length and support conditions, design shear steel reinforcement for thebeam (in light of ACI Code provisions for rebar spacing, rebar placement, rebar sizing,clear cover, etc.). The design may be needed along the whole beam span (where youhave to show various stirrup spacing schedules, or just at one particular location on thespan.

The question did not specify what the requirement is. You may elaborate more so I can provide you a…

As a design engineer you are asked to peer review the design done by another engineer at your organization. A typical reinforced concrete floor slab plan is given. Assume all members to be simply supported. The specified compressive strength of concrete is 5000 psi and Grade-60 steel is used. Unit weight of concrete can be assumed as 150 lb/ft³. B 30'-0"- B2 -EQ.- EQ. -EQ. SEC 1 -40'-0" IS B1 B3 B3 B1 2 The only dead load acting on the slab is the self-weight of the members. The live load on the slab is 100 psf. Initial cross-section and reinforcement details of beam B1 is shown. Area of steel is 4.8in². EQ. 40'-0" B EQ. North
c) What are limitation in Etabs ? Please answer the question according to your practice course d) What the differences between the options: Modeling, Analysis, Design and Detailing? e) How to define your beams columns ? please explain it briefly
Please draw a cross-section sketch and a plan view sketch showing the location and arrangement of both flexural and temperature/shrinkage reinforcement including center-to-center spacing. Using the following information: - Span: 11 feet - Dead load: 20 psf - Live load: 100 psf - Self-weight: 87.5 lb/ft2 - Concrete compressive strength: 4000 psi - Steel yield strength: 60,000 psi - Required thickness: 6 inches - Flexural reinforcement: two layers of #4 bars, spaced 9 inches center-to-center, with clear cover of 0.75 inches and depth of 1.5 inches from top of slab. - Temperature/shrinkage reinforcement: #3 bars, spaced 6 inches center-to-center, with clear cover of 0.375 inches and depth of .75 inches from top of slab. Please make sure sketch is clear and labled, thanks!
Designers typically specify longitudinal reinforcement on all four sides of a square column cross section for which of the following reasons? Check all that apply. Bending moments can act about two section axes, not just one O There is less chance for steel placement mistakes during construction There is additional axial strength compared to a design with longitudinal steel on only two sides
As a consultant, explain the required steps to give approval for casting the beam regarding to the following items:(i) framework(ii) main steel reinforcement(iii) secondary steel reinforcement
37 A simply supported beam 300 mm wide, 500 mm deep and spans 5.5 m supports a service super imposed dead load of 8 kN/m and service live load of 7 kN/m. Concrete strength f’c = 21 MPa and steel yield strength fy = 415 MPa. Concrete cover to bar centroid is 70 mm. Determine the required amount of tensile reinforcement in mm^2 as per provisions of NSCP 2015. Write your final answer to the nearest whole number.

Standard precast concrete beam and girder shapes. The heavier bars near the tops of the beams are mild steel reinforcing, and the smaller strands near the bottom are high-strength prestressing. Mild steel stirrups are also shown. Stirrups usually project above the top of the beam, as shown, to bond to a sitecast concrete topping, creating composite structural action. AASHTO (American Association of State Highway and Transportation Officials) beams were designed originally as efficient shapes for bridge structures. They have also found occasional use in parking garage structures or other utilitarian RECTANGULAR L-SHAPED INVERTED TEE AASHTO BEAM building types. ВЕAM ВЕAM BEAM య
