Skeletal Frame System
Precast Concrete building frames
Precast concrete components such as beams, columns, stairs and hollow core slabs to form the frame of buildings.
Skeletal frames are commonly used for relatively low-rise buildings which do not have many partitions. A common usage is in large-scale car parking buildings. Other common buildings built using frames are office buildings and commercial buildings.
The frames can be designed as moment-frames and often are either combined with precast shear wall systems or cast-in-situ shear walls.
The speed of construction and the high quality of the components are the main benefits of using precast skeletal systems. A building using a fully precast system can often be built at approximately 10-14 days per floor depending on the area and logistic limitations.
