• Rigid Frames
– Rigid frame structures are built at the site which may or may not be poured monolithically.
– Rigid frame structures provide more stability.
– Rigid frame structures resist rotations more effectively.
• Braced Frames
– Braced frame structures resist lateral forces by the bracing action of diagonal members.
– Braced frame structures are used to resist sideway forces.
– Buildings are braced by inserting diagonal structural members into the rectangular areas of a structural frame.
• Pin-Ended Frames
– A pinned frame has members connected by pins considered non-rigid if it would collapse when the supports are removed. A frame is considered to be rigid if it retains its original shape when the supports are removed.
• Fix-Ended Frames
– The structure in which one or more than one members are fully constrained.
• Gabled Frames
– Gabled Frames show a peak.
• Portal Frames
– It resembles like a door. Multi-story, multi-bay portal frames are commonly used for commercial and industrial construction.
– The members are usually made up of curved laminates and the members are thickened in the region of the knee or eaves joint to allow for the large moment.
