Disaster mitigation is a significant issue that must be addressed to avert the destructive impact of a disaster. Evaluation of the seismic performance of the structures is important to minimize the property damage and eliminate loss of lives against the hazardous effect of natural phenomenon such as earthquakes due to strength deterioration especially of the old buildings. The failure of structures disrupted the operation particularly on the post-disaster functions of school buildings. The Japan Building Disaster Prevention Association (JBDPA) Standard for seismic evaluation of existing reinforced concrete buildings is a detailed inspection method where the actual capacity of the structures to resist the seismic force can be determined. Moreover, proper retrofitting can be carried out to the vulnerable and essential structure to assure the safety of the building stakeholders. The JBDPA Standard focuses on the reinforced concrete structures with the concrete wall. The strength index of the masonry infill walls especially those with openings was determined from the equations of various experts. The two target structures, namely: Engineering Building 2 and four-story Administration Building are old and newly constructed buildings, respectively. The strength of the infill wall was added in the calculation of the seismic capacity of the school buildings. The backbone curve of the frame with reinforced masonry infill wall presented an informative result. The structures require retrofitting based on the first and second level screening. The result of the second level screening specified that only the first floor of the old and new buildings’ longitudinal axis need to be strengthened. The behaviors of the structures before and after retrofitting were analyzed in STERA 3D. Following the concept of the JBDPA Standard was found useful in the Philippines since many existing reinforced concrete school buildings with masonry infill wall need further evaluation. Furthermore, the proposed usage index ranges from 1.25-2.00 should be considered to emphasize the importance of the school buildings in post-disaster activities.
