Frames

The trusses and frames are the two most important structural members of civil engineering. Trusses are the interconnection of links and other structural members. The interconnection with other members makes the system behave as a single member that supports and transfers loads. Trusses are generally two types, plane truss, and space truss. Frames on the other hand form the skeleton of any building construction. Frames are structures formed by the connection of beams, columns, slabs, and joists. These members provide the building with the required structural support.

1) Consider the elevation view of an interior beam shown below. The beam has a t-shaped cross- section (the 5 in. thick slab is cast monolithically with the beam - meaning that the 22 in. deep beam has 17 in. hanging below the slab). The c-c length is 30 ft. Assume: M bw = 14 in. fc = 6 ksi Mu,neg. = 340 k.ft en = 28.5 ft Wu h = 22 in. fy = 60 ksi Mu,pos = 230 k.ft Sw = 12 ft - Length hstab = 5 in. No. 4 stirrups Column FL a. Select flexural reinforcement for the beam at midspan assuming it is singly reinforced. T- beams under positive bending are usually singly reinforced because the depth of the neutral axis in the flange is often smaller than the depth of any bars that might be present. Iterate until the design strength, Mn, exceeds M₁ by less than approximately 20%. Provide a drawing of the section design that clearly shows the location of the longitudinal reinforcement. Show the section complies with relevant ACI Building Code requirements (As,min, bar spacing limits, Et, min). b.…
