#### Rolled steel sections are classified

Rolled Steel sections are 1. equal angle 2. Unequal angle section 3. Bulb angles

#### For steel construction where secondary effects are considered without wind or earthquake loads, the permissible stresses on the members for connections, as specified, may be exceeded by

Secondary facts without wind or earthquake loads: out the permissible stress on the member or its connection a specified may be exceeded 25%. Secondary effect combined with wind or earthquake loads: increased by 25 percent in connection design(Rivet Bolt Tension Rod) and 33.33% in case of member design.

#### A plate used for connecting two or more structural member intersecting Each Other is called

Gusset Plate: thick steel plate used for joining two or more adjacent structure member. Base plate: used to connect column with RCC Foundation base Anchor plate: used at support as an anchor

#### A beam is defined as a structural member subjected to

Beam is subjected to transfer loading and column is subjected to axial loading

#### The method of design of steel Framework for greatest rigidity and economy in weight is known as

Method of design of steel framework: 1. Simple design: Western elastic theory. No moment is transferred from one to connected member to another connected member. Most and economical method 2. Semi rigid design: partially transfer of moment 3. Fully Rigid design: capable of transmitting moments and shear. It save weight of Steel and construction cost

#### The permissible bending stress in steel is

#### The heaviest I section for the same depth is

5 Types of Beam- ISJB: Indian Standard junior beam ISLB: Indian standard light weight beam ISMB: Indian Standard medium weight beam ISHB: Indian Standard heavy beam ISWB: Indian Standard wide flange beam

#### Standard loads are given in

Standard load IS 875 Dead load part 1 Live load part 2 WIND load part 3 Snow load part 4

#### Maximum thickness of main Steel member not exposed to weather is:

In steel structure minimum thickness of any member should not be less than 6 mm, when exposed to weather minimum thickness is 8 mm.

#### According to IS: 800-1984, the permissible stress in axial tension in steel is

Axial = 0.60 Fy Bending = 0.66 Fy Max Premissible Bearing = 0.75Fy Max average Shear = 0.40 Fy max Shear = 0.45 Fy

#### Factor of safety is the ratio of

#### The load factor applied to wind and seismic load in design of steel structure is

Maximum load combinations= 1.5(DL+LL) or 1.5(DL+WL/EL) or 1.2(DL+LL+WL)

#### Permissible stress may be known as

Permissible stress is fraction of yield stress with factor of safety

#### As per IS: 800, effect of safety adopted with respect to yield stress of steel is

#### Partial safety factor on steel stresses is

Partial safety factor for steel is 1.15 and for concrete 1.50

#### 1 cubic metre of mild steel weight about

#### Percentage increase of carbon in steel, decrease its

Ductility decreases with increase in carbon percentage

#### The common assumption that all rivets share equally a non-eccentric load is valid at a load

All rivets are assumed to to resist the same shear. Actually out rivet are subjected to greatest shear than inner rivets.

#### Rolled Steel T section are used

#### If P is wind pressure in Kg/cm2, v is velocity in km/hr and k is constant of proportionality then

As per IS 875 part 3 Design wind pressure Pz = 0.6 Vz2 Design wind velocity Vz = Vb(K1.K2.K3)
