Study Notes
Horizontal Members of a Concrete Frame
- The two main horizontal members in a concrete frame are beams and slabs.
Load-Carrying Element of a Building
- The primary load-carrying element in a building is the frame, which consists of columns and beams that support the building's weight.
Damage to Beams and Slabs
- If a beam or slab is damaged in a building, it can lead to a serious structural failure.
Concrete Composition
- The most common type of concrete used in building construction is Portland cement concrete.
- The process of mixing cement, sand, stone chips, and water to create concrete is called mixing.
Flowable Concrete
- A flowable mix of concrete is used in some situations to easily fill tight spaces and around reinforcement.
Concrete Strength
- The number in a concrete mix designation, such as M20, indicates the compressive strength in newtons per square meter.
Aggregates
- Aggregates are typically made of crushed stone, gravel, or sand, NOT steel chips.
Moment Connections
- Moment connections are used in both steel and concrete structures.
Loads Acting on a Building
- The two main categories of loads acting on a building are dead loads (permanent loads from the building itself) and live loads (variable loads from people, furniture, and other movable items).
Dynamic Loads
- Dynamic loads can occur in buildings, such as vibration from machinery or wind loads.
Wind Loads
- Wind loads are a concern for both short and tall buildings, depending on the building's shape and location.
Earthquake Loads
- Seismic loads, associated with earthquakes, cause the ground to shake horizontally and vertically, impacting structures.
Structures that Transfer Loads
- Foundations are the structures that transfer forces from a building to the ground.
Elevator Enclosures
- The vertical boxes that enclose elevators in a building are called elevator shafts.
High-Rise Building Walls
- Shear walls are commonly used in high-rise buildings to handle horizontal forces, such as wind and seismic loads.
Walling Materials
- The two main types of walling materials used in concrete frame buildings are brick and concrete block.
Finishing Brick and Concrete Surfaces
- The common method for finishing brick and concrete surfaces in concrete frame buildings is plastering.
Steel in High-Rise Buildings
- The main advantage of using steel in high-rise buildings is its high strength-to-weight ratio, allowing for slender structures with minimal material.
Steel in Industrial Buildings
- The key advantage of using steel in industrial buildings is its fast construction time and ease of assembly.
Steel Structures and Earthquakes
- While steel structures can be more prone to damage during earthquakes than concrete frame structures when not properly designed, they are not inherently more prone to collapse.
Conventional Steel Fabrication
- Bolted steel construction typically takes longer than conventional steel fabrication due to the added time required for bolting operations.
