## ACH 121 Lecture 05 (Structural Loads) Part 2Presentation Transcript

• STRUCTURES BUILDING SYSTEMS BUILDING LOADS STRUCTURAL FORCES STRUCTURAL MEMBERS
• STRUCTURES & BUILDINGS STRUCTURAL MEMBERS CONCEPTS IN BUILDING
• Columns
• Slender, rigid vertical element
• Supports axial compressive loads applied at the ends
• Distributes load from beams to foundation
Structural Members
• Beams
• Rigid, horizontal element rests on columns
• Span of a beam is determined by material and depth.
Structural Members
• Trusses
• Geometric frame based on triangles
• Members are subject both tension and compressive forces
Structural Members

• Lateral Solutions

Structural Members
• Structural Members
• Lateral Solutions
• Post and Beam (rigid frame)
• Beam resting on column, but MUST be braced
• Area filled in between post and beam becomes a loadbearing wall
• Slab (plate structure)
• Rigid, planar elements
• Distributes loads in multiple directions
Structural Members
• Arches
• Arches are curved element for spanning large openings
• Transfer the axial load to abutments on each side of the arch
• The length of the opening is proportional to the height of the arch
Structural Members
• Vaults
• Arched structure that forms a covering over a space
• Behaves as an arch with a third-dimension
• Two types
• Barrel
• Groin (cross)
