Variety of Forces

FS102: Unit 2 - Concepts of Construction
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
FS102: Unit 2 - Concepts of Construction
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
FS102: Unit 2 - Concepts of Construction
Types of Loads
Impact Loads○ Loads Delivered Quickly
Static Loads○ Applied Slowly and Constant
Repeated Loads○ Applied Intermittently
Wind Loads○ Applied by the Wind
FS102: Unit 2 - Concepts of Construction
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
FS102: Unit 2 - Concepts of Construction
Structural Members and Connections Structural Elements
○ Beams, columns, arches, and walls○ Differ on how they support and transfer
weight○ Structural frames
FS102: Unit 2 - Concepts of Construction
Structural Members and Connections Beams

Suspended BeamGirder - Transfer Beam
FS102: Unit 2 - Concepts of Construction
Structural Members and Connections Columns
Transmit a compressive force along a straight path
I-Beams vs. H-Beam

FS102: Unit 2 - Concepts of Construction
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
FS102: Unit 2 - Concepts of Construction
Structural Members and Connections Main divisions of walls (con’t):
○ Panel ○ Curtain ○ Party○ Fire○ Partition ○ Demising ○ Rubble masonry ○ Wythe
FS102: Unit 2 - Concepts of Construction
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.
FS102: Unit 2 - Concepts of Construction
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.
