Test: Steel Design- 1 - Question 1

### The forces acting on the web splice of plate girder are

Detailed Solution for Test: Steel Design- 1 - Question 1

A joint in the web plate provided to increase its length is known as web splice. The plates are manufactured up to a limited length. When the maximum manufactured length of the plate is insufficient for full length of the plate girder, web splice becomes essential. They are mainly used in Bridges. Splices in the web of the plate girder are designed to resist the shear and moment at the spliced section. The splice plates are provided on each side of the web.

Test: Steel Design- 1 - Question 7

Which of the following types of riveted joint is free from bending stresses?

Test: Steel Design- 1 - Question 8

Which one of the following methods of design is not suitable for structures subjected to impact and fatigue?

Detailed Solution for Test: Steel Design- 1 - Question 8

Connection such as riveted, bolted and welded can be design as flexible, semi-rigid or rigid connections. Flexible connections are known as simple connections. Rigid design is done to resist both shear and bending moment at the connections whereas Semi rigid connections resist the bending moment in between flexible and rigid connections. While Plastic design method does not take into consideration the effect of impact, fatigue, creep and shrinkage etc.

Test: Steel Design- 1 - Question 11

In roof trusses, the most frequent used section is

Detailed Solution for Test: Steel Design- 1 - Question 11

Angle sections are more resistant towards buckling than plate sections. Connections between angles are simple, and fabricated with ease, whether they’re bolted or welded. Angles offer a wide range of variety as you can use them singly, back to back and star shaped.

Four angle sections are used in Compression members.

Test: Steel Design- 1 - Question 12

As per Indian Standards, rolled steel Beams are classified into

Detailed Solution for Test: Steel Design- 1 - Question 12

The rolled steel beams are designated by the series to which beam sections belong (abbreviated reference symbols), followed by depth in mm of the section and weight in kN per metre length of the beam, e.g., MB 225 @ 0.312 kN/m.

As per IS 808:1989, Hot rolled I sections are classified in to 5 series:

i) Indian Standard Joist/junior Beams (ISJB)

ii) Indian Standard Light Beams (ISLB)

iii) Indian Standard Medium Weight Beams (ISMB)

iv) Indian Standard Wide Flange Beams (ISWB)

v) Indian Standard Heavy Beam (ISHB)

Test: Steel Design- 1 - Question 13

Consider the following statements:

1. Young's modulus of Aluminium is approximately equal to one-third of Young's modulus of steel

2. The disadvantage of Aluminum is that the deformation is high for a given load and it is costlier than mild steel

3. Aluminium is increasingly used for structural purposes because it requires less maintenance.

4. Strength to unit weight ratio of Aluminium is very low

The correct statements are:

Detailed Solution for Test: Steel Design- 1 - Question 13

Young's modulus of steel is approximately three times as that of aluminium, that's why its strength to unit weight ratio is high. In situations where high deformations are not acceptable aluminium can't be used. Aluminium is increasingly used for structural purpose because it requires less maintenance. The biggest disadvantage of aluminium is that the deformations are high for a given load and it is costlier than mild steel.

4. Minimum width of lacing bars in riveted connection should be three times the nominal diameter of the rivet

Detailed Solution for Test: Steel Design- 1 - Question 14

As per IS 800 Design specifications are:

1. The angle of inclination of the lacing with the longitudinal axis of the column should be between 40° to 70°.

2. The slenderness ratio of the lacing bar should not exceed 145.

3. Minimum width of lacing in riveted connections should be:

Test: Steel Design- 1 - Question 20

A steel beam supporting loads from the floor slab as well as from wall is termed as

Detailed Solution for Test: Steel Design- 1 - Question 20

Spandrel beam: Supporting load from exterior wall and slab and spanning from column to column.

In the case of high rise buildings, the masonry walls are usually not able to withstand their self-weight and the slab weight. In such cases, the beams are provided with exterior walls at each floor level to support the wall load and perhaps some roof load also. These beams are termed as spandrels.

Stringer beams: These are secondary beams (typically used in truss bridges) to carry the load from the slab till the cross beams located at truss nodes. You can see them in roof systems supported by trusses too. Basically, their purpose is to convert distributed loads to point loads (at truss nodes).
