TLDR
In this paper, the authors discuss the seismic bridge design philosophy and conceptual design in general as well as discuss U.S. seismic design practice to illustrate the process of seismic design.Abstract:
Bridges are very important elements in a modern transportation system. Recent earthquakes, particularly the 1980 Loma Priets and the 1994 Northridge Earthquakes in California, the 1995 Hyogo-Ken Nanbu Earthquake in Japan, the 1999 JiJi Earthquake in Taiwan, and the 1999 Kocaeli Earthquake in Turkey, have caused collapse of, or sever damage to, a number of major bridges. Since the 1989 Loma Prieta Earthquake, extensive research has been done on seismic design and retrofit of bridges in Japan and the United States, especially in California. This chapter will discuss the seismic bridge design philosophies and conceptual design in general as well as discuss U.S. seismic design practice to illustrate the process. The chapter will also briefly presents seismic design practice in Japan.read more

Probability density evolution method for seismic displacement-based assessment of earth retaining structures
Yu Huang,Hongqiang Hu,Min Xiong +2 more
TL;DR: As a novel dynamic reliability method based on random vibration theory, PDEM combines stochastic dynamic analysis with current advanced deterministic methods to assess the seismic performance of earth-retaining structures in earthquake-prone areas.

Structural Performance of Bridges in the Tohoku-Oki Earthquake
Kazuhiko Kawashima,Ian G. Buckle +1 more
TL;DR: Including minor non-structural damage, over 1,500 highway bridges and numerous rail bridges were damaged during the Tohoku-oki earthquake of 11 March 2011 as discussed by the authors.

Railway vehicle induced vibration energy harvesting and saving of rail transit segmental prefabricated and assembling bridges
TL;DR: In this article, a new type of electromagnetic vibration energy harvesters (EM-VEHs) is proposed to exploit the track slab vibration to supply enough power for strain collection units or GPS data transmission units in bridge health monitoring system.

Seismic Design and Retrofit of Bridges
TL;DR: In this article, the authors focus on designing adequate displacement and ductility capacity into new bridges, with less significance placed on strength, where a strength hierarchy is established in a bridge to ensure that damage is controllable and occurs only where the designer intends.
Journal ArticleDOI
Response spectrum method for multi‐support seismic excitations
TL;DR: In this article, a new response spectrum method is developed for seismic analysis of linear multi-degree-of-freedom, multiply supported structures subjected to spatially varying ground motions, including variations of the ground motion due to wave passage, loss of coherency with distance and variation of local soil conditions.

Myths and fallacies in earthquake engineering ― conflicts between design and reality
TL;DR: In this paper, the attitude of seismic analysis and design is deliberately iconoclastic, tilting at targets it is hoped will not be seen as windmills, and a pure displacement-based design approach is advanced as a viable alternative.
