Kolom Praktis
STRUCTURE & PHYSICSintermediate
Definition
A small reinforced concrete column embedded within a masonry wall, typically 12×12 cm to 15×15 cm in section, placed at wall intersections, corners, and at regular intervals along long wall runs. Kolom praktis are not primary structural columns — they do not carry floor or roof loads — but act as vertical ties that prevent masonry walls from buckling or collapsing in the event of seismic activity. They are a defining feature of Indonesian reinforced masonry construction.
Example
Indonesian SNI (Standar Nasional Indonesia) construction guidelines require kolom praktis at every wall corner and at maximum 3-metre intervals along straight wall runs — a requirement widely applied in low-cost housing construction across the archipelago.
