What type of support condition allows rotation but prevents translation in both horizontal and vertical directions?
Answer: Pin support
A pin support provides two reaction forces (horizontal and vertical) and allows rotation, but prevents translational movement in any direction.
Hooke's Law states that stress is proportional to strain within which material range?
Answer: Elastic range
Hooke's Law applies only within the elastic (linear) range of material behavior, where the material returns to its original shape after load removal.
What is the purpose of a moment connection in a steel frame?
Answer: To transfer both shear and bending moment between connected members
A moment (rigid) connection is designed to transfer bending moments as well as shear forces, making the joint behave as a continuous rigid structure.
Which load combination is required by ASCE 7 for strength design under dead load plus live load?
Answer: 1.2D + 1.6L
ASCE 7 specifies the factored load combination 1.2D + 1.6L as the primary gravity load combination for LRFD strength design.
What does the slenderness ratio (kL/r) of a column primarily affect?
Answer: Its susceptibility to buckling
A higher slenderness ratio means the column is more susceptible to elastic (Euler) buckling, reducing its allowable compressive load.
In reinforced concrete design, what is the primary role of steel reinforcing bars (rebar)?
Answer: To resist tensile stresses that concrete cannot handle
Concrete is weak in tension, so steel rebar is placed in tension zones to carry tensile forces and prevent cracking and failure.
