82 reinforced concrete buildings from 30 schools of Medellín, Itagüí and Sabaneta (Colombia) were surveyed during the year 2013 by a group of civil engineer students and a master student from the Universidad EAFIT. All of the analysed buildings are moment resisting frames with masonry infill. Buildings were analysed with the Priority Index methodology initially proposed by Hassan and Sözen (1997).
The Priority Index (PI) is defined as the sum of the wall index (WI) and the column index (CI), as follows:
Where Acw and Amw are the sum of the area of reinforced concrete and masonry walls, respectively, at ground floor in a given direction; Af is the total areas above ground level; and Acol is the total column area at the base level. The wall index is calculated for both principal longitudinal axes, the smallest value is used for the calculation of the Priority Index.
One of the parameters in the index calculation is the wall area, which provides lateral resistance. If a wall has openings and/or is constrained in only one end, its lateral resistance decreases. In this work three different criteria were considered for the calculation of the wall index value as follows:
- Areas of walls without openings that have columns on both ends.
- Areas of walls without openings that have columns on both ends, and
- Areas of walls with an opening on top of the wall. Opening maximum height of 60 cm and same length as the wall.
The area of the walls cross section was reduced by a factor of 0.7 for walls with openings with a height between 40 and 60 cm, and by a factor of 0.8 to 0.9 for openings with a height less than 40 cm.
- Areas of walls without openings that have columns on both ends,
- Areas of walls with an opening on top of the wall. Opening maximum height of 60 cm and same length as the wall,
- Areas of walls that have a column only on one end, and
- Sections of walls between openings
Pictures of three surveyed schools are presented next.
