CONFINED COLUMN FOR EARTHQUAKE RESISTANT CONSTRUCTION

This book has been researched for quite a long time so that it can be given an illustration that reinforced concrete columns given confinement can provide a significant increase in strength. Reinforced concrete column is one of the important elements of the building structure to withstand earthquake loads. However, the reality in the field is often not strong against lateral forces in the form of earthquake load pressure. Therefore, the concept of confinement on reinforced concrete columns is needed internally and externally.

In recent years, an effort has increased the need to upgrade the existing reinforced column structure. In the planning of concrete columns there are often errors in construction design. Then, the damage in a column of reinforced factors caused by earthquake or environmental events. In existing reinforced concrete structures, columns always receive a lot of attention in considering the performance based design philosophy adopted by almost all seismic codes, so the most appropriate concept used to improve column performance is confinement. This concept is an excellent method for strengthening reinforced concrete columns because it is able to produce a large enough confinement effect without increasing stiffness and mass elements. This book provides an overview of a reinforced concrete structure that is confined and the discussion of the book is proven to increase the strength of reinforced concrete columns due to adequate reinforcement design with a given confinement effect function. The confinement are in the form of the concept of internal reinforcing confinement and the concept of external confinement.
