Beams (3)
Frames (1)
• Combination of columns and beams • Loads experienced by frames varies ▫ Connections between the columns and beams • Frames experience three types of displacements ▫ Vertical displacement
• Beam shapes vary • Most often used: ▫ T Beams ▫ L Beams ▫ I Beams ▫ Rectangular Beams
▫ Horizontal displacement ▫ Rotational displacement
Columns (1)
Frames (2)
• Vertical structure designed to carry compressive loads • Experience compressive load and a bending moment • Columns are usually: ▫ Circular with helical reinforcement ▫ Rectangular with rectangular reinforcement
• Cast into forms on the site ▫ Forms are too large ▫ Geometrically complex ▫ One and Two – Way slabs • Pre – cast at the manufacturing plant ▫ Hollow core slabs ▫ T Beams and rectangular beams ▫ Girders ▫ Columns
