Study Notes
Graphic Statics
- Utilizes graphical methods to analyze the forces in structures and visualize equilibrium.
- Helps in determining the internal forces and reactions in static structures.
Racking Failure Prevention
- A braced frame is specifically designed to prevent racking failure by providing stability and resistance to lateral movements.
Force Transfer in Structural Engineering
- Facilitates the transfer of loads from beams to supports, ensuring proper load distribution and structural integrity.
Moment of Force
- Refers to the tendency of a force to cause rotation about an axis, calculated as the product of force and the perpendicular distance from the axis to the line of action of the force.
Force Polygon
- A graphical representation used to illustrate the equilibrium of forces, enabling easier visualization of how loads are balanced within a structure.
Stability Against Lateral Loads
- Shear walls provide stability against lateral loads, such as those from wind or seismic activity, by resisting horizontal forces.
Stiffness Property
- The stiffness of a structural element dictates its resistance to deformation; stiffer elements exhibit less deformation under the same load.
Stress Resistance Term
- The term "strength" is used to describe the ability of material to withstand applied stress without failing.
Axial Stiffness Equation
- The equation for stiffness (rigidity) in axial stiffness is given by ( k = \frac{EA}{L} ), where ( E ) is the modulus of elasticity, ( A ) is the cross-sectional area, and ( L ) is the length of the element.
Stress-Strain Behavior
- Non-linear plastic strain behavior describes how materials deform plastically under stress, showing a curve rather than a straight line in the stress-strain diagram.
Forces Induced by Wind
- Wind forces induce lateral loads on structures, which must be accounted for in design to ensure stability and safety.
Typical Unit for Stress
- In English units, stress is typically measured in pounds per square inch (psi).
Strain Calculation Formula
- Strain is calculated using the formula ( \text{Strain} = \frac{\Delta L}{L_0} ), where ( \Delta L ) is the change in length and ( L_0 ) is the original length.
Forces Induced by Earthquakes
- Earthquake forces induce dynamic loads that can affect the stability of structures, requiring consideration in structural design and analysis.
