Activity 1.1.1 History of Civil Engineering and Architecture

Introduction

Can you name any of the Seven Wonders of the Ancient World? Each was a feat of civil engineering and architecture. What causes structures such as these to fill us with awe even today? What is it that makes them seem more wondrous in our time of modernization? These structures have paved the way for many new advances in the design of the structures you see today.

In this activity you will learn about the history of civil engineering and architecture. You will see differences between the two professions and learn of their beginnings.

Procedure

In this activity you will investigate the history of civil engineering and architecture. You will see differences between the two professions and learn of their beginnings. Copy and paste the following questions in your blog, and answer them in a different color.

1.     Define civil engineering.
Deals with the design, construction, and maintanence of bridges, buildings, roads, canals, and dams. Build public works.

2.     Define architecture.

Combination of art and science. Gernerally design buildings for human habitation. Concerned with aesthetics.

3.     Describe the origination of the concept of architecture?

Architecture originated in Rome. The key concepts were durability, utility, and beauty.

4.     In ancient times how were building materials chosen?

Chosen based on avaibability and climate.

5.     Give two examples of vernacular architecture.

Mud huts with thatched roofs made of grass are an example. Igloos of ice are another example.

6.     Name and describe the type of system used to create many early buildings.

Post and lintel. The post was a vertical column of stone and the lintel which was a stone piece placed horizontally over two columns.

7.   What was the purpose of the Egyptian pyramids? Mexican pyramids?

They were built as burial places for their pharaos. The Mexican pyramids were built for religious and other uknown purposes.

8.     What kind of construction method was used to build the Parthenon? Made a simple sketch to illustrate.

Post and lintel

9.     What problem in architecture led to this form of construction?
It is easier to build an opening than cutting out an opening in a building.

10. Explain how an arch is created.
An arch conisists of at least two posts, the arch, and a keystone that holds the structure together.

11.  How is the vault used in civil engineering?
Used to build long hallways and tunnels.

12.  Give an example of an arch and dome system.

The capitol building roof.

13.  Give an example of a modern material we have that was not available to the ancients. How did this restrict construction in ancient times?

We have steel. Without steel, civil engineers could not use long large horizontal beams becuase of stone's terrible tinsle strength.

14.  What was the purpose of the Roman aqueducts?

They brought clean water from the mountains down to the city.

15.  Compare ancient Greek roads to ancient Roman roads.

Greek roads were merely flattened dirt roads while Roman roads were layered with stone.

16. Describe an ancient Roman bridge.

They were arched and made of wood or stone and mortar. Their basic structure was an arch, which is a very strong shape.

17. How did building materials and methods change after the Romans.
???

Conclusion

1.     Give an example of a modern pyramid not shown in the presentation. How does its function differ from that of the Egyptian pyramids? What do you think accounts for this difference?

There are green house pyramids. Obviously, these pyramids are built to house plants instead of dead people and we don't use stone to build the structures. We no longer build pyramids for dead people because we have different customs when it comes to burying our dead. Also, we have better, cheaper materials for building pyramids.

2.     Give an example of a modern structure that uses an arch and dome system.
Astronomy domes.

3.     What is the main purpose of modern roads? How is the cost of modern roadways defrayed?

The main purpous of modern roads is to create routes for vehicles so they may easily travel to many places.

Basic facts you ought to know about me.
