N1 - Funding Information:
The subject of nonlinear seismic analysis and response of bridges drew increasing attention in the early 1970’s. Since then, research in this particular area has significantly progressed with the research funding given by the following major agencies and organizations: Federal Highway Administration (FHWA), California Department of Transportation (CALTRAN), Federal Emergency Management Agency (FEMA), National Cooperative Highway Research Programs (NCHRP), and National Science Foundation (NSF). A review of the existing analysis models for bridge structures is provided below. Tseng and Penzien [l] studied the coupled inelastic flexural behavior of pier columns by using a three-dimensional elasto-plastic model, and the discontinuous behavior of expansion joints by employing a nonlinear mathematical model. Chen and Penzien [2] proposed an efficient three-dimensional time-history analysis method by incorporating four different types of elements, namely, solid elements for the surrounding soils, isoparametric beam elements for the bridge deck, pier columns, and pier caps, frictional elements for the interfaces between the soils and abutments, and boundary elements for considering the foundation flexibilities at the bases of pier columns. Effects of separation, impact, and slippage at soil-abutment interfaces were taken into consideration in their model [2]. Toki [3] contributed to the study of nonlinear responses of continuous bridges subjected to traveling seismic waves. Corsanego et al. [4] compared the nonlinear seismic effects of soil on bridge foundation response using various analytical techniques. Imbsen and Penzien [5] developed a nonlinear beam-column element for pier columns for evaluating energy-absorption characteristics of highway bridges, which includes a kinematic hardening

N2 - A simplified and practical approach for nonlinear seismic analysis of highway bridges is proposed. Efficiency and effectiveness of the proposed model is discussed in detail. The effects of soil-structure interaction, analysis methods, and bridge skews on bridge responses are also carefully examined. The results obtained from the simplified model are compared to those of refined models. The paper concludes with a number of real bridge examples and recommendations.
