2. What is a Structural Engineer? Bridges Some of the larger structures that we see around the Bay Area are bridges. These very large structures are designed by structural engineers who specialize in bridges. Some of our older bridges were designed in the 1930s. We may know more about earthquakes now, and these bridges will be strengthened, or replaced. Some of the larger structures that we see around the Bay Area are bridges.

3. Buildings What is a Structural Engineer? Most structural engineers are involved with buildings. New buildings in the United States are designed to strict building codes. The codes are the rules for design and construction. The codes in California are much stricter than in other parts of the country. This is because we have large earthquakes in California. Our building codes include all the lessons we have learned from past earthquakes like the 1989 Loma Prieta and 1994 Northridge earthquakes. New buildings need to be designed for many different things. First, to resist gravity loads, or to hold themselves up. Then, buildings in seismic areas are also designed to resist the lateral, or horizontal loads that earthquakes produce. Since the layout and aesthetics of new buildings are typically designed by Architects, structural engineers provide architects with information on the structural system and structural elements.

4. What is a Structural Engineer? Prevent EarthquakeDamage In many areas of the world, including the Bay Area, structural engineers do a lot of work to make buildings safer during earthquakes. Earthquakes are natural hazards that do not happen very often. However, the consequences of earthquakes can be very serious and, often, life threatening. The role of the structural engineer in society is very important. Their job is to prevent life-threatening damage due to earthquakes, both by designing new structures properly and by fixing old ones.

5. Design of New Bridges & Buildings What does a Structural Engineer do? These are pictures of the new construction at the San Francisco airport. Structural engineers helped design and construct many new buildings, bridges, and parking garages here. Structural engineers build mathematical computer models that represent the building structure. The models are then loaded with lateral loads that represent the earthquake. Using the mathematical model, the computer program analyzes the stresses that the individual structural elements may experience in an earthquake. With this information the structural elements can be sized to resist large earthquakes without experiencing life threatening damage. The new buildings and bridges at the San Francisco airport each had a detailed computer model made for their design. These are pictures of the new construction at the San Francisco airport.

6. Design of New Buildings What does a Structural Engineer do? One of the most important decisions that a structural engineer makes is what materials and earthquake resisting system should be used. Buildings are constructed of wood, concrete, masonry, steel or some combination of materials. These buildings are made of steel. The steel columns and beams resist gravity loads. The building on the left is a steel braced frame, and the one on the right is a steel moment frame. You can see the steel columns here and the steel �X� braces here. The braces are designed to resist earthquake forces. One of the most important decisions that a structural engineer makes is what materials and earthquake resisting system should be used.

7. What does a Structural Engineer do? Design of New Buildings Lately there are many new buildings being built around the Bay Area because the economy is doing well. There are many types of buildings: from office buildings, to school buildings, to churches, to hospitals, and even houses. All of them need to be designed by structural engineers so that they stand up under their own weight, in earthquakes or high wind, and are safe.

8. Retrofit of Old Buildings What does a Structural Engineer do? While we design to strict building codes that include new information on earthquakes, older buildings may have been constructed to out-of-date codes. Consequently, they may require retrofit to make them safer. Structural engineers evaluate the existing buildings and make recommendations for strengthening. Strengthening may include putting in new concrete walls or new steel braces. Because there is not much space left in the Bay Area to build new buildings, structural engineers do a lot of work retrofitting old buildings.

9. Retrofit of Old Buildings What does a Structural Engineer do? This is a picture of the San Francisco City Hall. It was damaged in the 1989 Loma Prieta earthquake but it did not collapse. The seismic retrofit of this building was just completed. The Structural Engineers used a new technology called base isolation. This photo shows rubber bearings that act like shock absorbers, and allow the ground to move under the building. The bearings will isolate the building from the earthquake ground motion.

10. Retrofit of Historic Buildings What does a Structural Engineer do? One of the most challenging retrofit jobs is the strengthening of an historic building. Some buildings, like this older ornate church, have expensive and detailed finishes. They may have detailed tile mosaics or marble finishes on the walls. The structural engineers who do historic preservation have to introduce new structure that will protect the church in an earthquake but will not disturb the beautiful finishes of the building.

11. What is a Structural Engineer? Shoring/Excavation When a new building is constructed, it might need a deep basement or foundation. This is typical of new high rises that will have underground parking. Some structural engineers specialize in shoring. They design the structure that will hold back the soil around the location of the new foundation or basement. Some of these shoring structures can get very deep as you can see in the middle picture.

12. Repair of Damaged Buildings What does a Structural Engineer do? Following an earthquake, structural engineers are needed to help building owners make repairs. The building on the left was damaged in the 1989 earthquake. The first floor was seriously damaged but the top floors did OK. A structural engineer may work with a contractor to design a system for shifting the building back into place and repairing and strengthening the structure. The building on the right is a church that was damaged by fire. A structural engineer worked with the owner, an architect, and a contractor to repair the building and to save the church.

13. New Technology What does a Structural Engineer do? Like any profession, structural engineering involves new technology. Some new items are shown in these photos. This is a damper that works just like a shock absorber in a car. As the floors of a building try to move relative to each other in an earthquake, the damper pushes back, to slow down the movement. This is a close up of the base isolation bearing I described earlier, and an illustration of the different building response with these isolators and without.

14. The Building Team Structural engineers are part of a team that builds or retrofits a building or bridge. The top of the team is the building or bridge owner. Directly below is the architect. In many projects, the structural engineer works for the architect, providing their expertise with regards to the structure. The contractor is also directly under the owner. All of the various construction workers work for the contractor. Building a building is a collaborative effort that requires communication and team building skills. The project structure is sometimes different from this. For many repair, retrofit, or reports when structural engineering expertise is necessary, the structural engineer will work directly for the owner.

19. At Work� �In Meetings What is a typical day like? Most structural engineers work in an office and have their own desk. At work, they collaborate with each other and with older engineers that they work for, and learn from. I have about 5 years of experience and my typical day on average consists of about 2 hours on the phone with clients and other team members, 2 hours working on the computer, 2 hours doing calculations, and 2 hours working with other engineers in my office. Despite the emphasis on math and science in school, engineering involves written and verbal communication skills. Most engineering work is team work, and teams need to communicate. A mis-communicated idea will lead to mistakes in design or at the construction site. Most structural engineers work in an office and have their own desk.

20. Client Service� What is a typical day like? Structural engineers also spend a lot of time providing service to their clients in many areas. Clients can be from many different areas of business- anyone who owns or rents a building, like these companies I�ve shown. A lot of a structural engineers work comes from repeat business from the same client. Therefore, good communication and performance with clients is vital to the success of a structural engineering firm. Some clients that have a lot of buildings need many different types of service. The same client may need consultation on their buildings, retrofitting of their buildings, and design of their new ones. For example, we have reviewed almost all of the Kaiser hospitals and medical office buildings,and have either built or retrofitted several of them. We have also set up a plan following an earthquake where we make sure their buildings are safe so that they can provide care to the injured.
