Chapter One
Push and PullStructural Engineering
What You Need to Know
Structural engineering is the branch of engineering concerned with the design and construction of all types of structures such as bridges, buildings, dams, tunnels, power plants, offshore drilling platforms, and space satellites. Structural engineers research the forces that will affect the structure, then develop a design that allows it to withstand these forces.
A force is a push or a pull on an object. The two basic forces on a structure are lateral forces (forces directed at the side of a structure) and vertical forces (forces directed up or down on a structure). Lateral forces on a structure might include wind (moving air).
The main vertical force on a structure is gravity (force pulling an object downward, which is toward the center of Earth). Weight is the measure of the force of gravity on an object. The weight of an object depends on mass, which is the amount of substance in the object. The greater the mass, the greater the weight; thus, the greater the force of gravity.
Engineers refer to the gravity force acting on a structure as the sum of its dead and live forces. Dead forces are the weight of the permanent parts making up the structure. In a building, dead forces include the weight of the walls, floors, and roof. Live forces are the weight of temporary objects in or on a structure. In a building, live forces include the weight of people, furniture, and snow on the roof. In the figure, live forces include the weight of the wagon, the child, and the boy; dead forces include all the parts making up the bridge. The total
