STRUCTURES AND FORCES-FILL IN THE BLANKS

 

A FAMOUS STRUCTURE

Now, we will watch the following video: 

Task 1: Fill in the blanks

Hi, I'm Veronica jolla california travel tips here outside the glorious golden gate bridge in San Francisco.
 
Let's learn a little bit more about the golden gate bridge. Its history, architect and some little-known facts.
 
The Golden Gate Bridge history dates back to its proposal in 1916.
 
Construction began in _____ and 35 million dollars later, the bridge officially opened to traffic on May 28 ______
 
It was the ______ suspension bridge in the world until ______ the record has been beaten several times.
 
Since then as we passed through the _____ gate began our crossing by car.
 
I wondered how long is the golden gate bridge.
 
We learned it's about 1.7 miles from _________ to ____ with a 40 200-foot _________ span 
 
Engineering ________ marvel at the Golden Gate Bridge blueprints _______ by joseph strauss in irving morrow.
 
Until then it was called the bridge that couldn't be ______ due to rough ocean currents, heavy fog and 60 mile-per-hour winds.
 
The vista point on the Marin County side is the ______ place to stop and _____   ______ of the Golden Gate Bridge.

Task 3: Check your Golden Gate bridge drawing that you did during the last lesson. Can you find any of these shapes?
 
 
figures images
 
Can you find any of these basic structural steel shapes?
basic structural steel shapes
 
 
Task 4: Glossary.
 
Those elements that are interconnected in such a way so as to constitute a structure are called structural elements.
 
Beam: Beam is a flexure member of the structure. It is subjected to transverse loading such as vertical loads, and gravity loads. These loads create shear and bending within the beam.
 
Columns: A long vertical member mostly subjected to compressive loads is called column.

A compressive member of a structure is called strut. 

Beam-Column: A structural member subjected to compression as well as flexure is called beam column

Grid: A network of beam intersecting each other at right angles and subjected to vertical loads is called grid

Cables and Arches: Cables are usually suspended at their ends and are allowed to sag. The forces are then pure tension and are directed along the axis of the cable. Arches are similar to cables except hath they are inverted. They carry compressive loads that are directed along the axis of the arch.
