1.
A simply supported steel beam spans 30 ft and carries a uniform factored load of
2.4 kip/ft over the entire span. What is the maximum factored bending moment?
A. 180 kip-ft
B. 240 kip-ft
C. 270 kip-ft
D. 360 kip-ft
Answer: 270 kip-ft
Rationale: For a simply supported beam under uniform load, Mu=wL2/8. Thus
Mu=(2.4)(302)/8=270 kip-ft.
2.
A reinforced-concrete rectangular beam is tension-controlled under a flexural
load combination. Which failure characteristic is most desirable?
,A. Concrete crushing before yielding of tension steel
B. Yielding of tension reinforcement before significant concrete crushing
C. Compression reinforcement yielding before tension reinforcement
D. Shear failure before flexural yielding
Answer: Yielding of tension reinforcement before significant concrete crushing
Rationale: A tension-controlled section provides ductile behavior and warning
through reinforcement yielding before concrete compression failure.
3.
For a steel compression member, increasing the effective slenderness ratio KL/r
generally causes which change?
A. Increased elastic buckling strength
B. Decreased buckling susceptibility
C. Decreased critical buckling stress
D. Increased yield stress
Answer: Decreased critical buckling stress
Rationale: Euler-type buckling resistance varies inversely with the square of
slenderness. A larger KL/r therefore significantly reduces compression capacity.
4.
A column has an effective length factor K=1.0, unbraced length of 15 ft, and
radius of gyration of 3 in. What is its slenderness ratio?
A. 45
B. 60
C. 75
D. 90
Answer: 60
Rationale: Convert 15 ft to 180 in and calculate KL/r=(1.0)(180)/3=60.
,5.
Which condition most directly causes lateral-torsional buckling of a steel beam?
A. Compression flange is continuously braced
B. Compression flange is insufficiently braced
C. Web is very thick
D. Beam is subjected only to axial tension
Answer: Compression flange is insufficiently braced
Rationale: Lateral-torsional buckling occurs when the compression flange can
move laterally and the cross section twists under flexural compression.
6.
A steel W-shape has a compact flange and compact web and is adequately braced
against lateral-torsional buckling. Which limit state may control its positive
bending strength?
A. Plastic moment capacity
B. Elastic buckling of the web only
C. Euler column buckling
D. Tensile rupture of the flange
Answer: Plastic moment capacity
Rationale: A compact, adequately braced beam can develop its plastic moment
before local or lateral-torsional buckling controls.
7.
For a bolted bearing-type steel connection, increasing bolt pretension alone does
not necessarily increase the nominal bearing strength of the connected plate
because bearing strength primarily depends on:
A. Bolt color and installation temperature
B. Edge distance, bolt diameter, plate thickness, and material strength
, C. Beam span only
D. Concrete compressive strength
Answer: Edge distance, bolt diameter, plate thickness, and material strength
Rationale: Plate bearing and tear-out depend strongly on geometry and
material properties around the bolt holes.
8.
A steel tension member contains staggered bolt holes. When determining net
section rupture, which geometric effect must be considered?
A. Only gross area
B. Staggered-hole path through the section
C. Column effective length
D. Beam lateral bracing
Answer: Staggered-hole path through the section
Rationale: A staggered rupture path can have a net width different from a
straight-line path, requiring the appropriate stagger correction.
9.
A welded connection develops a longitudinal force through a fillet weld. Which
weld dimension most directly determines the effective throat?
A. Weld length only
B. Leg size multiplied by approximately 0.707 for a standard 45° fillet
C. Plate width
D. Electrode diameter alone
Answer: Leg size multiplied by approximately 0.707 for a standard 45° fillet
Rationale: For a standard equal-leg fillet weld, the effective throat is
approximately 0.707w, where w is the weld leg size.
