Consider the following statements related to design of tension members with single structural shapes and plates: 1. The common single structural shapes are angle sections, tee sections, and channel sections. 2. Single angles are not used for bracing, for light truss tension members. 3. Occasionally, I sections are also used as tension members as they have more rigidity. Which of the above statements are correct?

Option 1 : 1 and 3 only

Explanation:

Design of tension members with single structural shapes and plates:

  • The common single structural shapes are angle sections, tee sections, and channel sections.
  • Angles sections are used for bracing, for light truss tension members, and also resist small compression if reversal of stress takes place.
  • I sections are also used as tension members as they have more rigidity and are also used for heavier building or bridge trusses.

  • In the design of tension member, when a member is required to take the heavy tensile load, a built-up section consisting of two or more plates is used.

Consider the following statements regarding channel routing : 1. In channel routing, the flood hydrograph at various sections of the reach is predicted by considering a channel reach and an input hydrograph at the upstream end. 2. As the flood wave moves down the river, the shape of the wave does not change. 3. Flood waves passing down a river have their peaks attenuated due to friction. 4. The addition of lateral inflows can cause an increase of attenuation. Which of the above statements are not correct  ?
