A simply supported beam 300 mm wide, 500 mm deep and spans 5 m supports a service super imposed dead load of 6 kN/m and service live load of 9 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.

The loadsshown on the beam with a cross section at midspan as shown, are service (unfactored)loads. The concrete used is a normal weight concrete with compressive strength of 4000 psi.The yield strength of the reinforcement is 60,000psi. For the midspan section shown, computeφMn and show that it exceeds Mu
What is the shear force to be carried by the reinforcements of a beam subjected to axial tension if it has a width of 313 mm and an over-all depth of 477 mm? The specified compressive lightweight concrete is 22.2 MPa and the yield strength of stirrups is 333 MPa. The distance of tension reinforcements from the outer fiber of the beam is 59 mm. Round off your final answer in 3 decimal places. Loadings: VDL = 72 kN %3D VLL = 62 kN Axial Tension (DL) = 90 kN Axial Tension (LL) = 19 kN
Subject reinforcement concrete design please show all steps so your process is easy to follow
PLEASE ANSWER IT NOW HELP. For the reinforced concrete beam shown, calculate the bending stresses (fc, fs,and fs') in the concrete and reinforcement for a service-load bending moment of 115 kN-m. Assume normal-weight concrete with fc'=28 MPa and Grade 60 reinforcement (fy=415 MPa). Assume a cracked section
pls help need answer right now thank you so much
Determine the reinforcement ratio for a concrete with the following specifications: f'c =5000psi, 18 inches wide, 36 inches high, #5 stirrups placed at 12 inches on the center, longitudinal reinforcement if four #14 bars, clear cover to stirrups is 2 inches
NEED ASAP! USE NSCP 2015(REINFORCE CONCRETE DESIGN SUBJECT) determine the Concrete Shear Force and Critical Spacing of Stirrups to be adopted by the entire grid distance.Convert all the dimensions from ft and inches into millimeters (use 1 inch = 25mm for distance and dimension approximations). Use the following parameters: fc' = 21 MPa, fy = 420MPa, fyt = 275 MPa, Wdl = 23.7 KN/m, WII = 16 kN/m.
