Concrete design
Problem #1: Design a rectangular beam section, i.e. select b, d, h, and the required area of tension steel, A, at mid-span for a 22 ft-span simply supported beam that support its own weight, a superimposed service dead load of 1.25 kip/ft, and a uniform service live load of 2 kip/ft. Start by assuming the self-weight of the beam W-410 lbs/ft, b-0.7d, and use fc4500 psi and fy-60, 000 psi Note: Provide a detailed sketch for the final...

Design a rectangular simple supported beam to carry service loads of 1.05 kips/ft of dead load (DL) (self-weight included) and 2.47kip/ft live load (LL) on a span length of 18 ft. The beam is limited to be (due to architectural reasons) 10” wide with an overall depth of 20”. Use f’c= 3,000 psi and fy= 40,000psi. Design the longitudinal reinforcement (flexure design) and the web reinforcement (Stirrups).

Reinforced Concrete Design
Design a rectangular beam section for the load given W(dead) =29.40kN/m, W(live) = 43.20kN/m, L1=4.82m, L2= 1.5m, use row(p)=0.18f'c/fy. Beam weight is not included in the loads shown. fy = 414 MPa, f’c = 28 MPa. Live loads are to be placed where they will cause the most severe conditions at the sections being considered. Select the beam size for the largest moment (positive or negative), and then select the steel required for maximum positive and negative moment. Assume concrete...

design the following rectangular floor beam for a building. The beam has a simple span of 21ft. The uniform service load is 520lbs/ft live load. Consider the self-weight of the beam as dead load. Assume f’c = 4,000 psi, fy = 60,000 psi, and #3 stirrups. Required: a) Conduct a free-beam design for the above conditions.
For Problems 1 and 2, design rectangular sections for the beams.
Loads and Density values are shown. Beam weights are not included
in the loads shown. Show sketches of cross sections, including bar
sizes, arrangement, and spacing. Assume concrete weighs 150
lb/ft3, fy = 60,000 psi, and fc′ =4000 psi, unless given
otherwise.
