STRUCTURAL MODELING AND ANALYSIS ENGAGE

Question 1

This ability allows engineers to design more resilient, innovative, and economical structures that are increasingly more necessary to meet global growth and sustainability demands.

Answer 1

Structural Modeling

Question 2

The most common mathematical solution used to perform computational simulation

Answer 2

finite-element analysis method

Question 3

involves idealization of a physical structure, its support conditions, and its applied loading, in a mathematical framework, to determine the structural behavior of the structure.

Answer 3

finite-element analysis method

Question 4

individual components of a structure are mathematically idealized as discrete (finite) line, surface, and volumetric elements.

Answer 4

finite-element analysis method

Question 5

connected to each other at nodes

Answer 5

Finite elements

Question 6

applied at locations of nodes (loads can be also applied to elements directly, but eventually, they are later resolved to nodes)

Answer 6

Loads and boundary constraints

Question 7

the displacements (translations and rotations), called degrees of freedom (DOFs), at each node

Answer 7

primary unknowns

Question 8

Types of Finite-Element Analysis

Answer 8

LINEAR ANALYSIS
NON-LINEAR ANALYSIS

Question 9

• assumes that the structure undergoes small displacements
• members remain elastic
• determines the elastic stiffness of each element
• relationship between loads and displacements is proportional and linear.
• displacement and forces from every load condition can be determined in isolation.
• resulting displacements and forces can then be factored and combined with other load condition results as prescribed by the building code load combinations.

Answer 9

LINEAR ANALYSIS

Question 10

• utilized when a structure undergoes large displacements or when materials go beyond their elastic limit and a more accurate simulation of structural behavior is required.
• analysis must be performed for each combination of gravity and lateral loads acting together.
• This type of analysis involves an incremental-iterative numerical solution in which structural response is traced for incremental load increments.

Answer 10

NON-LINEAR ANALYSIS
