Unit-I: Introduction to Structures - Foundation 3. Which of the following is an example of a permanent structure?
Scaffolding
Tent
Bridge
Exhibition booth
A structure's lifespan depends on:
Material quality
Environmental factors
Maintenance practices
All of the above
The substructure of a building includes:
Roof and walls
Foundation and footing
Columns and beams
Doors and windows
The superstructure refers to:
The parts of the building below ground level
The parts of the building above ground level
Foundations only
Both substructure and superstructure
What is the primary role of the substructure?
To support the roof
To distribute loads to the ground
To create aesthetic appeal
To provide insulation
The substructure should:
Resist lateral forces
Prevent differential settlement
Be constructed above ground level
Only support vertical loads
In a load-bearing structure, walls:
Are non-load-bearing
Carry the entire structural load
Support only the roof
Are supported by beams
Framed structures rely on:
Walls for load distribution
A skeleton of beams and columns
Only the foundation
Roof trusses
Load-bearing structures are suitable for:
High-rise buildings
Small to medium-sized buildings
Earthquake-prone areas
Large open spans
One advantage of framed structures is:
Reduced construction time
Increased rigidity of walls
Fixed room sizes
Inefficient load distribution
Framed structures are commonly made of:
Timber only
Reinforced concrete or steel
Brick masonry
Plastic composites
The ability of soil to support loads is called:
Settlement capacity
Bearing set
Load resistance
Structural strength
The maximum pressure soil can withstand without failure is called:
Safe bearing capacity
Ultimate bearing capacity
Allowable stress
Plastic limit
The safe bearing capacity of soil considers:
No safety factor
Ultimate strength only
A safety factor to prevent failure
Water content of the soil only
Which soil type has the highest bearing capacity?
Sand
Clay
Rock
Silt
A clayey soil's bearing capacity:
Increases with moisture content
Decreases with moisture content
Is unaffected by moisture content
Is always higher than sand
Silt is characterized by:
High bearing capacity
Low bearing capacity
Excellent drainage properties
Strong cohesion
Which factor does not affect soil bearing capacity?
Type of foundation
Location
Water table level
Color of the soil
Shallow foundations include:
Piles
Rafts
Caissons
Wells
Deep foundations are used when:
Soil near the surface has low bearing capacity
Construction time needs to be reduced
The building is less than 3 stories tall
Water table is very low
Pile foundations transfer loads through:
Skin friction only
End bearing only
Both skin friction and end bearing
Compression
A common cause of foundation failure is:
Proper soil testing
Uneven settlement
Uniform load distribution
High bearing capacity
Foundation failures are often due to:
Use of deep foundations
Overloading or erosion
Uniform soil conditions
Excessive reinforcement
Differential settlement can lead to:
Strengthening of the structure
Cracks in walls and foundations
Uniform load distribution
Soil stabilization
Grouting is a remedial measure for:
Weak foundations
Load redistribution
Foundation waterproofing
Beam construction
Underpinning is used to:
Increase bearing capacity of soil
Strengthen or deepen existing foundations
Prevent waterlogging
Reduce construction costs
Brick masonry is:
The construction of walls using stones
The construction of walls using bricks bonded with mortar
The construction of walls using steel
None of the above
A course in brick masonry refers to:
A vertical layer of bricks
A horizontal layer of bricks
The mortar used between bricks
The reinforcement in walls
The bed in brick masonry is:
The horizontal surface on which bricks are laid
The vertical joint between bricks
The decorative face of the wall
The reinforcement used in masonry
A header is:
A brick laid flat with its longest side parallel to the wall
A brick laid flat with its shortest side exposed in the face of the wall
A decorative brick in masonry
A brick used for corner reinforcements
A stretcher is:
A brick laid with its longest side parallel to the wall face
A brick laid perpendicular to the wall face
A vertical joint in masonry
A tool used to smooth mortar
The purpose of a bond in brick masonry is to:
Add decorative elements to the structure
Provide strength and stability by interlocking bricks
Reduce construction costs
Ensure mortar consistency
The strongest and most commonly used bond in brick masonry is:
Flemish bond
English bond
Stretcher bond
Header bond
In an English bond, the courses of bricks consist of:
Headers only
Stretchers only
Alternating courses of headers and stretchers
Randomly placed bricks
Which bond has better aesthetic appearance but slightly less strength than an English bond?
Stretcher bond
Header bond
Flemish bond
Zigzag bond
Bricks used in masonry should:
Have high water absorption
Be of uniform size and shape
Be lightweight
Have rough edges
To ensure proper bonding, bricks should be:
Laid dry
Soaked in water before use
Heated before use
Painted before use
The overlap between bricks in successive courses should be at least:
Half the length of the brick
One-fourth the length of the brick
The full length of the brick
No overlap is required
Efflorescence in brick masonry occurs due to:
Excessive load on walls
Presence of salts in bricks or mortar
Poor compaction of mortar
Uneven settling of foundation
The defect in brick masonry caused by improper curing is:
Cracks
Spalling
Bulging
Erosion
The defect in masonry where bricks disintegrate due to frost action is called:
Spalling
Bulging
Efflorescence
Peeling
Bulging in brick masonry occurs due to:
Weak mortar mix
Poor alignment of bricks
Overloading of walls
All of the above
A defect in brick masonry caused by the growth of vegetation is:
Cracks
Spalling
Moss or plant growth
Efflorescence
The most effective way to ensure durability in brick masonry is:
Using high-quality bricks and mortar
Avoiding water during construction
Reducing overlap between bricks
Leaving vertical joints unfilled
A joint in stone masonry refers to:
The horizontal line between two stones
The gap between stones filled with mortar
A reinforcement bar used in stone masonry
The bond between two stones without mortar
A quoin is:
A rough stone used for corners
A large stone placed in the middle of a wall
A corner stone that is often more prominent
A stone placed at the top of the wall
Rubble masonry consists of:
Stones of uniform size and shape
Roughly dressed stones with varying sizes
Stones that are only laid without mortar
Stones laid only with cement
In ashlar masonry, stones are:
Rough and uneven
Finely dressed and uniform in size
Randomly arranged
Only used for decorative purposes
Coursed rubble masonry is:
Made of large, irregular stones
Made of stones laid in uniform horizontal courses
Made of finely finished stones with equal dimensions
Only used for the construction of decorative walls
To ensure stability, stones should be laid on:
Their natural bed
The flattest side only
Any random side
The roughest side
The tool used to shape stones is called a:
Hammer
Chisel
Trowel
Plumb bob
The tool used to smooth mortar is:
