  2. Cremona diagram - Wikipedia

    en.wikipedia.org/wiki/Cremona_diagram

    In a next phase the forces caused by wind must be considered. Wind will cause pressure on the upwind side of a roof (and truss) and suction on the downwind side. This will translate to asymmetrical loads but the Cremona method is the same. Wind force may introduce larger forces in the individual truss members than the static vertical loads.

  3. Free body diagram - Wikipedia

    en.wikipedia.org/wiki/Free_body_diagram

    A body is said to be "free" when it is singled out from other bodies for the purposes of dynamic or static analysis. The object does not have to be "free" in the sense of being unforced, and it may or may not be in a state of equilibrium; rather, it is not fixed in place and is thus "free" to move in response to forces and torques it may experience.

  4. Direct stiffness method - Wikipedia

    Each element is then analyzed individually to develop member stiffness equations. The forces and displacements are related through the element stiffness matrix which depends on the geometry and properties of the element. A truss element can only transmit forces in compression or tension.

  5. Zero force member - Wikipedia

    en.wikipedia.org/wiki/Zero_force_member

    In a truss, a zero-force member is often found at pins (any connections within the truss) where no external load is applied, and three or fewer truss members meet. Basic zero-force members can be identified by analyzing the forces acting on an individual pin in a physical system. If the pin has an external force or moment applied to it, then ...

    The second diagram is the loading diagram and contains the reaction forces from the joints. A simple triangular truss with loads imposed . Since there is a pin joint at A, it will have 2 reaction forces. One in the x direction and the other in the y direction. At point B, there is a roller joint and hence only 1 reaction force in the y direction.

  7. Flexibility method - Wikipedia

    en.wikipedia.org/wiki/Flexibility_method

    In structural engineering, the flexibility method, also called the method of consistent deformations, is the traditional method for computing member forces and displacements in structural systems. Its modern version formulated in terms of the members' flexibility matrices also has the name the matrix force method due to its use of member forces ...

  9. Structural load - Wikipedia

    en.wikipedia.org/wiki/Structural_load

    A structural load or structural action is a mechanical load (more generally a force) applied to structural elements. [1] [2] A load causes stress, deformation, displacement or acceleration in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements.
