4.1 The precast concrete beam shown below is subjected to a live load of 1300 lb/ft and a superimposed dead load of 520 lb/ft in addition to its self-weight. Design the beams as a rectangular section. Assume interior beam, ¾" MAS, #4 stirrups, ?? ′ = 5,000 ???, normalweight, ?? = 60,000 ??? (use only #6 or #7 bars for reinforcement). Span- 20-ft

A rectangular, tension-reinforced beam is to be designed for dead load of 500 Ib/ft plus self weight and service live load of 1200 Ib/ft, with a 22 ft simple span. Material strengths will be fy 60 ksi and J 16 in. Calculate the required beam width and tensile steel requirement, using a reinforcement ratio of 0.60po.o0s. Use ACI load factors and strength reduction factors. The effective depth may be assumed to be 2.5 in. less than the total depth steel...

The single-story unbraced frame shown below is subjected to dead load, roof live load, and wind load Figure 1 shows the results of a first-order analysis relative to the columns of the frame. The axial load and end moment (also equal to the maximum moment in the column) are given separately for the different load cases (i.e., dead load, roof live load, and lateral wind load). All vertical loads are symmetrically placed and contribute only to the Mnt moments (i.e.,...
