  2. Structural load - Wikipedia

    en.wikipedia.org/wiki/Structural_load

    For example, in designing a staircase, a dead load factor may be 1.2 times the weight of the structure, and a live load factor may be 1.6 times the maximum expected live load. These two "factored loads" are combined (added) to determine the "required strength" of the staircase.

  3. Structural engineering theory - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering_theory

    A typical load case for design for serviceability (characteristic load cases; SLS) is: 1.0 x Dead Load + 1.0 x Live Load. Different load cases would be used for different loading conditions. For example, in the case of design for fire a load case of 1.0 x Dead Load + 0.8 x Live Load may be used, as it is reasonable to assume everyone has left ...

  4. Structural analysis - Wikipedia

    en.wikipedia.org/wiki/Structural_analysis

    The first type of loads are dead loads that consist of the weights of the various structural members and the weights of any objects that are permanently attached to the structure. For example, columns, beams, girders, the floor slab, roofing, walls, windows, plumbing, electrical fixtures, and other miscellaneous attachments.

  5. Limit state design - Wikipedia

    en.wikipedia.org/wiki/Limit_state_design

    In determining the specific magnitude of the factors, more deterministic loads (like dead loads, the weight of the structure and permanent attachments like walls, floor treatments, ceiling finishes) are given lower factors (for example 1.4) than highly variable loads like earthquake, wind, or live (occupancy) loads (1.6).

  6. Curtain wall (architecture) - Wikipedia

    en.wikipedia.org/wiki/Curtain_wall_(architecture)

    Dead load. Dead load is defined as the weight of structural elements and the permanent features on the structure. [7] In the case of curtain walls, this load is made up of the weight of the mullions, anchors and other structural components of the curtain wall, as well as the weight of the infill material.

  7. Structural integrity and failure - Wikipedia

    en.wikipedia.org/wiki/Structural_integrity_and...

    Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.

  8. Howe truss - Wikipedia

    en.wikipedia.org/wiki/Howe_truss

    A 10-panel truss requires counter-braces in every panel but the end panels, and these should be at least one-half as strong as the braces. A Howe truss bridge can be strengthened to achieve a live load to dead load ratio of 2-to-1. If this ratio is 2-to-1 or greater, then a six-panel truss must have counter-braces and these must at least one ...

  9. Progressive collapse - Wikipedia

    en.wikipedia.org/wiki/Progressive_collapse

    The building was a steel-frame design, and the collapse was the first known example of the total progressive collapse of a steel-framed building. [3] On May 16, 1968, the 22-story Ronan Point apartment tower in West Ham, London suffered a fatal collapse of one of its corners because of a natural-gas explosion, which destroyed a load-bearing ...
