Skyscrapers by Virginia Loh-Hagan

Why do engineers design skyscrapers with materials that can bend during strong winds or earthquakes?

• So the building doesn’t break or collapse

• To make the building look more interesting

• Because flexible materials are cheaper

• To allow windows to open more easily

The book talks about how skyscrapers use steel frames inside to hold them up. Why do you think steel is a good material for this?

• Steel is heavy and makes the building sit firmly on the ground

• Steel is strong but flexible, so it can hold the building and bend without breaking

• Steel is colorful and makes the building look shiny

• Steel melts easily and helps keep the building cool

Why do you think skyscrapers became more popular as cities grew bigger?

• Because people wanted to build higher for better views

• Because cities needed more space for people and businesses on less land

• Because it was easier to build tall than wide buildings

• Because tall buildings are faster to build than short ones

How does the use of a steel frame change the engineering possibilities for skyscrapers compared to older building methods?

• It allows buildings to be taller because steel is stronger and lighter than traditional materials

• It makes skyscrapers more colorful and eye-catching

• It limits how tall buildings can be because steel is less flexible

• It makes buildings easier to paint and decorate

The book explains that skyscrapers must resist both vertical forces (like weight) and lateral forces (like wind). Why is this dual resistance important?

• Because only vertical forces affect the building’s shape

• Because lateral forces can push the building sideways, and vertical forces push it down, so both must be managed to prevent collapse

• Because skyscrapers only face vertical forces in earthquake zones

• Because lateral forces help hold the building up during storms

Based on what you read, why might engineers need to consider the surrounding environment (such as nearby buildings or underground conditions) when designing a skyscraper?

• Nearby buildings might block the sunlight

• It affects the foundation

• The building color needs to match the environment

• They build the same design everywhere.
