| 摘要: |
| The damage to the masonry-infilled reinforced concrete (RC) frame buildings in Charikot, the capital city of Dolakha district in Nepal, during the 2015 April-to-May Nepal earthquake sequence is reported. Most of these buildings were built by the owners with little governmental inspections regarding their structural design or constructional quality. Although they generally performed better than other structural systems such as stone-masonry houses, the RC frames sustained extensive damage ranging from cracking of infill to complete collapse. In particular, eight of the 72 inspected RC frames alongside an uphill street collapsed in different ways. In addition to the un-engineered nature of these RC frames, their collapse could also be attributed to multiple technical reasons including the effect of terrain, the pounding between adjacent buildings and the accumulative damage in the earthquake sequence. |
