考虑抗震设防的房屋建筑暴露度评估方法研究
Building Exposure Evaluation Method Considering Seismic Fortification Level
摘要
Abstract
Taking Fangshan District in Beijing City for example,we used the administrative unit's housing data,population statistics data and population density data to determine the geographical spatial distribution of building area in the district.Then,according to the building earthquake damage matrix,we used the replacement cost method and the market comparison method to evaluate the exposure of Fangshan's buildings.The re-sults indicate that①the values of Fangshan's building construction are 147.17 billion yuan and 3 216.299 billion yuan evaluated by the replace-ment cost method and market value method,respectively.②Based on the replacement cost method,the earthquake exposure are 6.45 billion yuan and 102.74 billion yuan evaluated considering seismic fortification level and without seismic fortification level,accounting for 4.38%and 69.81%of the total value of buildings in Fangshan,respectively.The evaluation that considering seismic fortification level may be closer to the maximum possible loss of an earthquake disaster,which improves the accuracy of earthquake risk assessment results and has important practical value.关键词
