Study Notes

Structural Elements

Structural elements are used to analyze complex structures, simplifying them into linear, surface, or volume elements.
Structural elements can be categorized by types of load, like tension members under tensile forces, and compression members under compressive forces.
Flexural members (beams) experience tension and compression across their depth.

Bars or Rods

Bars are categorized by their structural action and load type.
Height is considered when comparing bars' cross-sections.
Examples include beams and columns.

Columns

Columns are vertical structural components.
Examples of their use are in building foundations and bridges.

Structural Elements of Buildings

Buildings can be divided into different structural parts for analysis. These parts are structural elements.

Plates

Plates are three-dimensional solid elements with small thickness compared to other dimensions.
Plates in buildings include slabs.
Plates can have flexural bends.

Shells

Shells are structural elements often used as water tanks, domes, theaters, and stadiums.
Shells are volumetric shapes.

Blocks

Blocks are vertical plate elements, often part of walls that have thickness.
Walls and foundations are flexural elements.
Foundations are considered compression members.

Major Types of Structures

Bridges, buildings, dams, roadways, retaining structures, and offshore structures are common structural types.
Constructions are designed to avoid collapse by considering the soil characteristics on each side.
Constructions can also be built underwater.

Common Building Components

Superstructure: Above ground, including walls and roofs, to support building function.
Substructure: Below ground, supporting the superstructure's weight (includes foundations).

Different Types of Buildings

Buildings are classified by purpose (residential, educational, industrial).

Classification based on Structure

Load-bearing structures: Loads are transferred through walls to the ground.
Framed structures: Beams and columns support loads transferred to the ground through foundations.

Types of Loads

Dead loads: Constant, unchanging loads (walls, beams, columns).
Live loads: Variable based on occupancy (people, furniture).
Wind loads: Dynamic forces from wind on structures.
Earthquake loads: Forces resulting from earthquakes.
Erection loads: Forces during construction.
