1. (15 pts) What is the development length for the three 86 bars? Normal weight concrete...
Problem 2 Assume normal weight concrete with fe' = 3,500 psi and steel bars of Grade 60 (fy = 60,000 psi). For design loads assume dead load Po = 300 kips (including member self-weight) and live load P. = 400 kips. Design a short round spiral column for axial load only, assuming initially po = 4%. Form sizes are available in 2 in increments.
HELP! Problem 6 Development Length (30 pts.) The required reinforcement steel area "As" for the lightweight reinforced concrete beam of figure 3 is 2.88 si. The No. 8 top bars are uncoated. Compute the development length (d), İffy 60,000 psi and fc 3.500 psi. a) Use the simplified equation Table 8-1) b) Use the ACI Equation 25.4.2.3a (Equation 8-10) c) Use the ACI Equation 25.4.2.3a with Ktr 0 (Equation 8-10) 18 3" 3@4 123 3" 448 bars 3.14 in2 26...
Problem ll The figure below shows a cantilever beam with b = 12-in containing 3-No 7 bars that are anchored in the column by standard 90° hooks. fc 4500 psi (normal weight) and fy- 60,000 psi. If the steel is stressed to fy at the face of the column, can these bars: a) be anchored by hooks into the column? The clear cover to the side of the hook is 2 34 -in. The clear cover to the bar extension...
Problem 1 (50% 16.0 The normal weight reinforced concrete beam shown has a 15' cantilever span and the following properties fc 3000 psi fy - 40 ksi 18.0 6-10 bars (a) (10%) Determine the cracking moment of the beam. 24.0 Do not complete any code checks (min/max steel, min. beam width, etc.) 3.0
Qu estion 1: (25 points) The beam shown below has a span of 13 ft and is reinforced with bars that ext end 8 inch beyond the face of the support. The centerline of the longitudinal bars nearest the side ace (i.e., the "outside bars") is 3.5 inch from, the side face as shown below. The concrete has a compressive strength of 3.0 ksi, and the reinforcement is Grade 60. The beam is loaded with a distributed live load (w)...
