YOLANDA 2013 IN THE PHILIPPINES
The authors conducted surveys on damaged reinforced concrete (RC) buildings by Bohol Earthquake and Typhoon Yolanda (Haiyan internationally)in the Philippines, and found heavy damage in non-structural members, huge difference in degree of damage among buildings in similar situation, and each of heavily damaged buildings has its own specific causes. The causes could be categorized into 1) improper design, 2) poor/insufficient quality of materials, 3) poor workmanship/improper construction works, and 4) lack of maintenance works. This report introduces overview of damage and causes, considers the background and presents some recommendation on basic policy to improve the situation as 1) creation of common understanding of designs, 2) improvement on designs and description/documentation, 3) comprehensive capacity development of relevant stakeholders .
