FREE Bachelor of Civil Engineering Structural Analysis Questions and Answers
If the hospital is constructed of structural steel frames, what will be the value of Vmax in the previous question?
The value of R for structural steel frames is roughly 8, and Vmax = SDSW/(R/I).
If a structure has 2j - r members, it will be as follows:
Structures may be both stable and unstable in certain circumstances.
What is carried by the members of a truss?
Members of trusses can only support axial loads.
What is the load factor for H in the equation U-0.9D + 1.6W + 1.6H if H's structural action cancels out W's or E's?
Since lateral earth pressure opposes the action of other forces, H should be taken into account when designing resistance in this situation.
If consecutive structures in an internal beam are identical to one another, then the tributary area is:
Due to the similarity of the structures, the triangle's angles will be 45 and 90 degrees.
Why do short roof trusses have a base plate?
The long roof truss has a base plate on one end so that it can slide in the event of temperature changes.
Which one of the subsequent structural loads is not frequently applied to a building?
To buildings, three sorts of loads are always applied.
The moment necessary to rotate a structural member of a uniform section so that it produces a unit slope is known as ____ when it applies to only one end of the member.
The moment needed to rotate a structural member of uniform section so that it produces a unit slope when only one end of the member is subjected to a moment is known as the stiffness of the member. In essence, stiffness is a measurement of a member's resistance to rotational deformation.
Which of the following structures is statically determined?
There are three equilibrium equations that can be used to analyze double overhanging: ∑Fx=0, ∑Fy=0, and ∑M = 0.
How many unknowns would there be in a structural system if we used link support?
If link support is applied, there will only ever be 1 unknown, which is the force operating along the axis of the link.
Which building will fare best in an earthquake?
In the event of overloading, indeterminate structures have a propensity to transfer their load to their redundant supports.
What should be the bare minimum number of joints necessary for the stability of an equilibrium equation if a structure has a total of 10 joints?
Equilibrium equations need to be simultaneously satisfied at every joint of the structure for stability.
What is the maximum permissible decrease percent in the case of a structural member supporting more than one level with a load above 100psf?
Studies have revealed that a floor is rarely loaded with more than 80% of its design load in structures with more than one storey.
If the total gravity load is x and 10% of it is placed to the 10th level of a structure, what will the static lateral force there be?
Fx = 0.01wx.
Which building would require fewer materials overall?
Statically indeterminate would be less expensive since they have greater stability and can support a loading with thinner components.
Which of the following is not a component of trusses?
While being strong in compression, concrete is weak in tension.
