Variety of Forces

GravityExerts a continued force on a buildingThe gravity resistance system Unintended loads imposed by fire

Three Type of ForcesCompressionTensionTorsion


Types of Loads

Definition of Loads

Forces or other actions that result from the weight of all building materials, occupants and their possessions, environmental effects, differential movement, and restrained dimensional changes


Types of Loads Stress and Strain

Dead Load○ The weight of the building itself and any

equipment permanently attached

Live Load○ Any Load other than a dead load○ Concentrated Load


Types of Loads

Impact Loads○ Loads Delivered Quickly

Static Loads○ Applied Slowly and Constant

Repeated Loads○ Applied Intermittently

Wind Loads○ Applied by the Wind


Types of Loads

Axial Load○ A force that passes through the centroid of the

section

Fire Load○ Represents the potential fuel available to a

fire and the total amount of potential energy (heat) in the fuel

Suspended Loads○ Suspended from a ceiling or other structure


Structural Members and Connections Composite Materials

○ Steel and Concrete○ Brick and Block Composite Wall


Structural Members and Connections Structural Elements

○ Beams, columns, arches, and walls○ Differ on how they support and transfer

weight○ Structural frames


Structural Members and Connections Beams

○ Transmits forces perpendicular to the reaction pointsSimple - Built-Up GirderContinuous - Spandrel GirderFixed - LintelOverhanging - GrillageBracket - Cantilever BeamJoist -

Suspended BeamGirder - Transfer Beam


Structural Members and Connections Columns

Transmit a compressive force along a straight path

I-Beams vs. H-Beam


Structural Members and Connections Transmit the compressive forces applied

along the top or received at any point Main divisions of walls:

○ Load-bearing○ Non-load-bearing○ Cross○ Veneer ○ Composite ○ Header ○ Stretcher


Structural Members and Connections Main divisions of walls (con’t):

○ Panel ○ Curtain ○ Party○ Fire○ Partition ○ Demising ○ Rubble masonry ○ Wythe


Structural Members and Connections Connections

○ Transfer the load from one structural element to another

○ Only as strong as its weakest link○ Pinned○ Rigid-Framed Building○ Monolithic Concrete○ Wet Joint○ Plastic Design

Unit 2 Scenario: Forces Upon Buildings Review the scenario below and write a 1–

2 page paper (excluding cover page) that illustrates how forces and loads act upon buildings.

While conducting a pre-fire plan at a furniture and appliance store of heavy timber construction, you notice that heavy appliances are stored on the second floor of the structure. You also notice that the roof of the building is being renovated.


Unit 2 Scenario: Forces Upon Buildings

What do you think are the primary hazards that might be faced within this building?

How would the loads of furniture and appliances act upon the building?

How does the composite material of construction affect the building in this scenario?

Discuss how loads may be transmitted.
