G1- Structural Engineering Flashcards
(30 cards)
- Focuses on the framework of structures, and on designing those to withstand the stresses and pressures of the environment and remain safe, stable and secure.
Structural Engineering
- Are trained professionals who are responsible for making sure that the structures are safe, stable and don’t collapse under applied loads.
Structural Engineers
- Their duties include designing the structures, creating models using CAD software, analyzing loads and pressures, monitoring construction processes, and collaborating with contractors and project managers.
Structural Engineers
Structural Engineering dates back to _______ when Step pyramid for Pharaoh Djoser was built by Imhotep.
2700 BC
In 18th and 19th centuries, new materials like _____ and _____ changed everything.
iron and steel
In 20th century, we saw the rise of _________like the ___________.
skyscapers, Empire State Building
- Today, structural engineers focus on thing like?
earthquake-resistant buildings and eco-friendly designs.
- Is the process of examining and evaluating the behavior, strength, and stability of a structure under various conditions such as loads, forces and environmental factors
Structural Analysis
Types of Structural Analysis
- Static
- Dynamic
- Finite Element Analysis (FEA)
- Modal Analysis
the most common type, which examines the behavior under static loads such as its own weight, applied loads, and support reactions.
Static Analysis
considers the effects of dynamic loads such as wind, earthquakes, or vibrations. Helps assess how a structure responds.
Dynamic Analysis
a computational method to analyze complex structures by dividing them into smaller, more manageable elements. It provides detailed insights into stress distribution, deformation and other factors.
Finite Element Analysis (FEA)
studies the natural frequencies and mode shapes of a structure t understand its dynamic behavior and response to external forces.
Modal Analysis
Structural Design must account for movements and forces due to ____________ to avoid structural failure
temperature, creep, cracking, and imposed loads
If it exceeds Hooke’s law a structure is called as
Failure structure
Modes of Structural Failure
- Stress
- Deflection
- Buckling
- Creep
- Fracture
- Wear
- Yielding
Are classified as live (imposed) loads and dead loads.
Structural Load
Transitory or temporary lads
Live Loads
are permanent and may include the weight of the structure and all major permanent components.
Dead Loads
Basic forces or loads that can act on structure:
- Tension
- Compression
- Shear
- Torsion
- Structural engineering depends on the knowledge of materials and their properties, in order to understand how different materials support and resist loads.
Structural Material
Common materials are:
- Iron
- Concrete
- Aluminum
- Timber
- Composites
includes all structural engineering related to the design of buildings
- A branch of structural engineering close to architecture.
Building structures
engineered to withstand various types of hazardous earthquake exposures at the sites of their particular location.
