Problem 3: Variable Live Load Placement 24'-0" + 28'-0" 24'-0" This beam supports a Dead Load and a Live Load. The Dead Load is uniform across all spans. The Live Load is a uniform load that varies so that it could be on some, all, or none of the spans. Draw the various live loading scenarios that will generate the maximum moments (positive and negative) in the critical regions of the beam. This is a qualitative problem, so no analysis is required. If you would like to run the analysis, assume a Dead Load of 1.64 kip/ft and a Live Load of 1.00 kip/ft.

Concept explainers

Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.

This beam supports a Dead Load and a Live Load. The Dead Load is uniform across all
spans. The Live Load is a uniform load that varies so that it could be on some, all, or none of
the spans. Draw the various live loading scenarios that will generate the maximum
moments (positive and negative) in the critical regions of the beam.
