14. Seismicแผ่นดินไหว building loss estimation
Depending upon the earthquake intensity and the building strength, a building may get damage during an earthquake ranging from fine cracks in plaster to the total collapse of the building. When the earthquake intensity is considered constant, the damage grade is then directly related to the strength of a building, which again is related to the material and construction type adopted in the construction. Considering the seismic vulnerability, the buildings in the case study city have been divided into the following classes.
• Stone
• Adobe (AD)
• Brickอิฐตากแห้ง with Mud Mortar, Poorly built (BM)
• Brick with Mud Mortar, Well built (BMW)
• Brick with Cement or Lime mortar (BC)
• Reinforced Concrete Frame with Masonry having three or less stories (RCC3)
• Reinforced Concrete Frame with Masonry having more than 3 stories (RCC4)
The table Landuse contains an estimation of the fractions of buildings of the various types (AD, BM, BC and RCC) per landuse type.
