Seismic damage to schools subjected to Nepal earthquakes, 2015

摘要

Schools are the gathering place of the young generation. They are expected to act as a refuge after an earthquake. Even though Nepal has no building supervision system, the quality of school buildings receives necessary attention. During a field study conducted in mid-June, we summarised the seismic damage to 12 schools with various types of structures, including local characteristic reinforced concrete frames, cement-bonded or mud-bonded masonry and timber frames. The pros and cons of local construction technologies are discussed. Some interesting earthquake phenomena, such as the effects of forward directivity, site configuration, earthquake sequence and safe distance from a slope, are discussed. The geo-security evaluation of a proposed school site in mountainous Baramchi is also conducted.
