What do you mean by quality control of concrete?

 Properties of the cement used in the concrete. …  Properties of the concrete mix designed of use in the structure.  Control of the coarse aggregates and fine aggregates going into the concrete.  Mixing of the concrete.

What is a lug angle?

Lug angle is small piece of angle used to connect outstand legs of the members to the gusset plate. … area of the angle become effective in resisting tension. So if lug angle is used, then efficiency of the tension member increases because it reduces shear lag effect.

What is gusset base?

A gusseted base consists of a base of reduced thickness and two gusseted plates are attached one to each flange of the column. Gusseted Column Base. The gusseted plates, cleat angles and fastenings (bolts, rivets) in combination with bearing area of shaft shall be sufficient to take all loads.

What are the steel tension members?

What are steel tension members? Explanation: Steel tension members are those structural elements that are subjected to direct axial tensile loads, which tend to elongate the members. A member in pure tension can be stressed up to and beyond the yield limit and does not buckle locally or overall.

What are the various types of tension members?

The tension members made of structural steel can be broadly grouped into four categories:

  • Wires and Cables. The wire type tension members are used for derricks, hoists, hangers for suspension bridges, rigging slings, and guy wires.
  • Bars and Rods. …
  • Single Structural Plates and Shapes. …
  • Built-up Sections.

What are the different types of failure of tension members?

Modes of failure in tension members (a) Gross Section Yielding (b) Net section Rupture (c) Block Shear.

What are the factors that influence the strength of tension members?

The strength of these members is influenced by several factors such as the length of connection, size and spacing of fasteners, net area of cross section, type of fabrication, connection eccentricity, and shear lag at the end connection.
