Damage description: In many columns steel deformed rebar were found in column elements. Large openings at the first storey, slender, tall columns and rigid roofs/slabs and/or beams, causing soft-storey mechanisms and failure at the top of columns. No compliance with capacity design principles requiring that a beam develops plastic hinges while columns remain elastic or near yielding. Shear failure of colunns due to insufficient shear reinforcement with respect to flexural capacity. Short column shear failure, due to the presence of openings for light and air circulation. Low quality of materials, low strength of concrete and use of round stones from river beds as aggregate. Insufficient detailing of reinforcement: lengths and staggering of splicing, development lengths, transverse reinforcement for shear strength and confinement at element ends, small diameters of longitudinal reinforcement, excessive or insufficient cover of longitudinal reinforcement. Pounding at the ceiling level between independent units at expansion joints. All these above features were found all over the schools that sustained large damage.
