| Abstract | With the development of seismic design of building, the performance of structural components and systems have been focused for load resisting systems, on the other hand, nonstructural components are mostly overlooked in structural design analysis. During earthquakes, when the harmonization does not occur between structural and nonstructural parts, the nonstructural components which are not considered under seismic requirements are easily more fragile and damaged than structural components. The poor behavior of nonstructural components can trigger to structural load resisting systems when earthquake comes. Moreover, in previous earthquakes, the vulnerability of nonstructural building systems and components has been studied in buildings.
The objective of this study is to assess performance of nonstructural building components including architectural components, mechanical components and building contents in high rise buildings locating in Bangkok and Manila under three earthquake levels such as service level earthquake, design based earthquake and maximum considered earthquake. The performance of nonstructural components can be measured by nonstructural damage and the damageability can be translated to losses associating with social losses in term of serious injuries and casualties, direct economic losses regarding with repair cost and indirect losses relating with downtime and business interruption loss. Thus, this study provides the better understanding of nonstructural components from different aspects such as what structural demand parameters they are sensitive to, nonstructural damageability and damage consequences in term of losses.
Evaluating performance of nonstructural components for 37-story building in Bangkok known as moderate seismic zone, drift sensitive components are more damaged than other types of component and for 50-story building in Manila regarded as high seismic zone, it is found that nonstructural components are more damaged due to acceleration demand parameter. The number of serious injury is from 0 to 1 person and 1 to 22 people in the building in Bangkok and Manila correspondingly, and then the number of casualty is same ranginging from 0 to 1 person for each building. Direct economic cost due to nonstructural damage ranges from 1% to 3% of initial nonstructural replacement cost for 37-story building in Bangkok and it ranges from 2% to 24% of initial nonstructural replacement cost for 50-story building in Manila. Downtime to recover nonstructural damage is between 2.6 to 4 months for 37-story building in Bangkok and between 2.6 to 9 months for 50-story building in Manila. For individual case study building, business interruption cost is higher than direct economic cost due to nonstructural repairs. |
