#### 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.

#### 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.

#### 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.

#### 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.

#### What is carried by the members of a truss?

Members of trusses can only support axial loads.

#### 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).

#### 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 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 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.

#### 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.

#### Which one of the subsequent structural loads is not frequently applied to a building?

To buildings, three sorts of loads are always applied.

#### 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.

#### Which of the following structures is statically determined?

There are three equilibrium equations that can be used to analyze double overhanging:Â âˆ‘Fx=0, âˆ‘Fy=0, and âˆ‘M = 0.

#### If a structure has 2j - r members, it will be as follows:

Structures may be both stable and unstable in certain circumstances.

#### Which of the following is not a component of trusses?

While being strong in compression, concrete is weak in tension.

#### 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.
