Active Structural Systems Concepts

Eric Hernandez from the University of Vermont explains the concept of structural systems in five levels of difficulty. He covers active vector systems, active section systems, active form structures, active surface structures, and active height systems. Each system is described in terms of its structural mechanics and applications, with examples ranging from trusses and beams to skyscrapers and domes. The video aims to enhance understanding of structural systems and inspire further learning.

What is the primary goal of a structural system?

• To reduce the cost of construction

• To increase the weight of a building

• To solve a particular problem or achieve a common goal

• To create a decorative element

Which structural system relies on vectorial decomposition of external loads?

• Active Vector

• Active Form

• Active Section

• Active Surface

What is a key characteristic of truss structures?

• They are not economical

• They are primarily used in small buildings

• They are very shallow

• They require large depths for strength

How do Active Section systems derive their strength?

• Through parabolic shapes

• Through 3D geometry

• Through bending mechanisms

• Through vectorial decomposition

Which materials have enhanced the efficiency of Active Section systems?

• Plastic and rubber

• Glass and aluminum

• Pre-stress concrete and high strength steel

• Wood and brick

What is a common feature of Active Form structures?

• They are always rectangular

• They are made of wood

• They rely on two-dimensional shapes

• They are robust under all conditions

What is a characteristic of Active Surface structures?

• They are not efficient

• They are always flat

• They derive strength from 3D geometry and flexural mechanisms

• They are only used in small buildings

What is the primary challenge in designing Active Height systems?

• Balancing strength and stiffness for large vertical distances

• Using only one type of material

• Reducing the number of floors

• Achieving aesthetic appeal

Which structural system is used in skyscrapers to handle lateral and vertical loads?

• Active Surface

• Active Vector

• Active Section

• Active Height

What is an example of a building that uses Active Height systems?

• A small residential house

• Burj Khalifa

• A single-story office

• A wooden cabin
