JEE Main Paper 2 (B.Arch) Aptitude - Architectural Awareness Syllabus

Where is the Leaning Tower located and what type of structure is it?

Pisa, Italy; it is the freestanding bell tower (campanile) of the cathedral, tilting due to soft subsoil.

In which city is the Sagrada Família, and who is its architect?

Barcelona, Spain; Antoni Gaudí, in his distinctive Catalan Modernisme (Art Nouveau) style.

Define the architectural term 'pendentive.'

A curved triangular surface that transitions from the corners of a square space up to the circular base of a dome, transferring its weight to the supporting piers.

What is a 'flying buttress' and which architectural style is it associated with?

An external arched support that carries the lateral thrust of a vault/wall to a detached pier; characteristic of Gothic architecture.

Define 'pilaster' and how it differs from a column.

A pilaster is a flattened, rectangular column projecting slightly from a wall as decoration; unlike a true column it is not free-standing and bears little load.

What is a 'cantilever' in structural terms?

A beam or slab fixed/supported at only one end, projecting horizontally into space without external support at the free end.

List the three classical Greek orders of columns in chronological order.

Doric, Ionic, and Corinthian.

How do you visually distinguish Doric, Ionic, and Corinthian column capitals?

Doric: plain, cushion-like capital, no base; Ionic: scroll-like volutes; Corinthian: ornate acanthus leaves.

Name three defining features of Gothic architecture.

Pointed arches, ribbed vaults, flying buttresses (often also stained-glass rose windows and tall spires).

What are the defining features of Classical (Greco-Roman) architecture?

Symmetry and proportion, columns with classical orders, pediments, entablatures, and use of post-and-lintel plus (in Roman work) arches and domes.

Give two hallmark features that distinguish Mughal architecture.

Bulbous (onion) domes and pointed/cusped arches, often with minarets, char-bagh gardens, red sandstone and white marble, and pietra dura inlay.

What characterizes Modernist architecture compared with earlier styles?

Rejection of ornament, 'form follows function,' use of steel/glass/reinforced concrete, flat roofs, open plans, and clean geometric volumes.

Define 'facade' in architecture.

The principal exterior face or front elevation of a building, usually the one facing the street or main approach.

What is a 'colonnade'?

A long row of regularly spaced columns supporting an entablature or roof, often forming a walkway.

Differentiate a natural building material from a man-made (manufactured) one, with examples.

Natural materials occur in nature and are used with minimal processing (stone, timber, clay, bamboo, marble); man-made materials are manufactured/processed (cement, steel, glass, fired brick, plastics).

What gives marble its smooth texture and varied colours, and a typical use?

Marble is a metamorphic rock of recrystallized calcite; mineral impurities give veined colours. It is used for flooring, cladding, and sculpture (e.g., the Taj Mahal).

Name a building material prized for its warm colour, workability and renewability, and one weakness.

Timber (wood): warm tone, easily worked, renewable; weaknesses include susceptibility to fire, rot, and termite attack.

By texture and colour, how would you identify red sandstone versus white marble in Mughal buildings?

Red sandstone is coarse-grained, matte, reddish-brown (e.g., Red Fort, Agra Fort walls); white marble is fine, smooth, lustrous white (e.g., Taj Mahal dome).

What material is granite, what is its texture, and a common use?

Granite is a hard, coarse-grained igneous rock with a speckled grey/pink texture; used for durable flooring, kerbs, countertops, and load-bearing/cladding work.

What is reinforced cement concrete (RCC) and why is steel added?

Concrete cast around steel reinforcement bars; concrete is strong in compression but weak in tension, while steel resists the tensile stresses, so the composite handles both.

Define a 'column' and the type of force it primarily carries.

A vertical structural member that primarily carries axial compression, transferring loads from beams/slabs above down to the foundation.

Define a 'beam' and the type of internal forces it experiences.

A horizontal structural member that spans between supports and carries transverse loads, experiencing bending (and shear), with compression on one face and tension on the other.

What is an 'arch' and how does it carry load?

A curved structural member spanning an opening that converts vertical loads into compressive forces directed along its curve to the supports/abutments.

Name the central wedge-shaped stone at the top of an arch and its function.

The keystone; it locks the other voussoirs in place and transmits load evenly down the two sides of the arch.

Define a 'vault' and name two common types.

A vault is an arched structure forming a ceiling or roof over a space; common types are the barrel (tunnel) vault and the groin (cross) vault.

Define a 'dome' and the kind of force it generates at its base.

A hemispherical or curved roof spanning a space; it works mainly in compression but produces outward lateral thrust (hoop tension) at its base that must be restrained by a ring or thick walls.

What is the structural function of a foundation?

To transfer the building's total load safely to the soil/rock below and to distribute it so as to prevent excessive settlement or failure.

How does the built environment differ in urban versus rural settings?

Urban settings have dense, high-rise, compact buildings with planned infrastructure and little open space; rural settings have low-density, low-rise, scattered structures using local materials with abundant open land.

What does 'contextual design' mean in relating a building to its surroundings?

Designing a building so it responds to its site—climate, topography, neighbouring structures, local materials, and culture—so it harmonizes with rather than clashes against its context.

Why are vernacular materials and forms often used in rural built environments?

They are locally available and affordable, suit the local climate, reflect cultural traditions, and require traditional rather than industrial construction skills.

What is the difference between 'figure-ground' relationship and 'streetscape' in built-environment context?

Figure-ground analyses the pattern of solid built mass versus open void/space in a settlement plan; streetscape describes the visual character of a street formed by the buildings, frontages, and elements along it.
