This paper describes the development of seismic design provisions of highway bridges will be revised in Taiwan reflecting the destructive damage in the 1999 Chi-Chi earthquake. After the Chi-Chi earthquake, the revised seismic design force and other related requirements in the seismic design code for highway bridges are developed in Taiwan. In addition to the conventional force based design, a capacity checking level is considered for the near-fault sites by limiting the ultimate capacity to exceed the maximum possible seismic demand. The development of seismic design force and the capacity check method are described.

Seismic Design Code

New requirement is claimed for the seismic design method of long-span railway bridges with the rapid development of high-speed railway construction in China during the last decade. However, the present design code of our country seems not keep pace with the engineering practice. The existing method, although embodying the philosophy of performance-based earthquake resistance design framework, in ‘the seismic design code of railway engineering’ is only applicable to those girder bridges with spans smaller than 150m. Therefore, the authors introduce the anti-seismic design measures of highway bridges from the Current China Specification to check the seismic safety of a long-span railway arch bridge as an applying example. Different seismic fortification criterions and property objects of the structural system and components are supplied in order to optimize the anti-seism performance of this bridge. The numerical results show that this kind of approach is helpful to improve the dynamical properties and seismic performances of large span railway bridges.

This paper compares the provisions of near-fault effect factors considered in the representative design codes in the world. It is found that the different codes carry out different near-fault effect values. Chinese, American, and New Zealand seismic design codes clearly present the near-fault effect factors, and Chinese seismic design code relatively presents the smallest near-fault effect values among the three codes. While Japanese code accounts for near-fault effect using empirical method and strong motion evaluation employing earthquake source model. The consideration of the near-fault effects in European Standard is the simplest among the five codes.

Abstract. After the 2016 Gyeongju earthquake and the 2017 Pohang earthquake struck the Korean peninsula, securing financial stability for earthquake risk has become an important issue in Korea. Many domestic researchers are currently studying potential earthquake risk. However, empirical analysis and statistical approach are ambiguous in the case of Korea because no major earthquake has ever occurred on the Korean peninsula since Korean Meteorological Agency started monitoring earthquakes in 1978. This study focuses on evaluating possible losses due to earthquake risk in Seoul, the capital of Korea, by using catastrophe model methodology integrated with GIS (Geographic Information System). The building information such as structure and location is taken from the building registration database and the replacement cost for building is obtained from insurance information. As the seismic design code in KBC (Korea Building Code) is similar to the seismic design code of UBC (Uniform Building Code), the damage functions provided by HAZUS-MH are used to assess the damage state of each building in event of an earthquake. 12 earthquake scenarios are evaluated considering the distribution and characteristics of active fault zones in the Korean peninsula, and damages with loss amounts are calculated for each of the scenarios.
