LESSON-5 (1) Flashcards
TOPIC 1 (15 cards)
is a fundamental practice in civil and structural engineering that involves creating a representation or an animation of physical structures to predict their behavior under various conditions.
STRUCTURAL MODELING
used to understand, explain or predict something. They could be: Theoretical, Mathematical, Numerical, Phenomenological, or Structural.
Modeling
recreating a system, or a process, a phenomenon, or a problem by using a model.
Simulation
the process of assessing the effects of loads and forces on physical structures. It involves calculating the internal forces, stresses, and deformations in structural elements to ensure safety and functionality.
Analysis
EXAMPLES OF STRUCTURAL MODEL SIMULATIONS
- BLAST ANALYSIS
- EARTHQUAKE/SEISMIC ANALYSIS
- DYNAMIC LOAD ANALYSIS
- WIND ANALYSIS
- Predict and understand how the structure will perform under a variety of loads and environmental conditions, such as gravity loads, wind, seismic activity, temperature changes, and other factors.
- Ensure that the structure can withstand expected loads and stresses
without failure. This helps in identifying potential issues early in the design
process and ensures safety standards are met.
Structural Design and Analysis
- Optimize the use of materials to balance strength, cost, and weight.
- Minimize construction and maintenance costs by using structural modeling to identify the most economical design that still meets all safety and performance requirements.
Optimization of Materials and Construction cost
Ensure that designs comply with building codes and regulations, which often require detailed structural modeling to verify that all standards are met.
Adherence to Codes and Regulations
Purpose of Structural Modeling and Simulation
- Structural Design and Analysis
- Optimization of Materials and Construction cost
- Adherence to Codes and Regulations
Key Components of Structural Modeling
- GEOMETRY
- MATERIAL PROPERTIES
- TYPES OF LOADS
- BOUNDARY CONDITIONS
- ANALYSIS METHOD
- VISUALIZATION TOOLS
Define the shape and dimensions of the structure. This includes the layout of beams, columns, slabs, foundations, and other components.
GEOMETRY
Incorporate various loads that the structure will encounter, such as dead loads, live loads, wind loads, seismic loads, snow loads, and thermal effects.
Types of Loads
How the structure is supported and restrained, including fixed supports, roller supports, and pinned connections
Boundary Conditions
Analysis Method
Referring to the computational techniques used, such as linear or nonlinear analysis, static or dynamic analysis, and finite element analysis (FEA), the choice of method can affect the accuracy and reliability of the simulation results.
Graphical representations of the structure and results are often included in software packages. Thus, choosing more advanced software leads to a better understanding of the complex behavior of structures.
