Design of Steel Structures MCQ with detailed explanation for interview, entrance and competitive exams. Explanation are given for understanding.

Question No : 57
The elastic strain for steel is about

1/12 of strain at the initiation of strain hardening and about 1/120 of maximum strain

1/2 of strain at the initiation of strain hardening and about 1/12 of maximum strain

1/12 of strain at the initiation of strain hardening and 1/200 of maximum strain

1/24 of strain at the initiation of strain hardening and about 1/200 of maximum strain

Question No : 58
According to the Unwin's formula, if t is thickness of the plate in mm, the nominal diameter of the rivet, is

d = 1.91 t

d = 1.91 t2

d = 1.91 √t

d = 1.91 t

Parallel to flanges

Parallel to web

Perpendicular to flanges

Perpendicular to web

Question No : 60
Effective sectional area of a compression member is:

Gross sectional area - area of rivet hole

Gross sectional area + area of rivet hole

Gross sectional area × area of rivet hole

Gross sectional area + area of rivet hole

Question No : 61
The maximum spacing of vertical stiffeners is

1.33 d

1.25 d

1.5 d

1.75 d Where d is the distance between flange angles

Question No : 62
