An Investigation of the Effectiveness of Existing Bridge Design Methodology in Providing Adequate Structural Resistance to Seismic Disturbances. Phase II: Analytical Investigations of the Seismic Response of Long Multi -Span Highway Bridges
Descriptions are given to the analytical investigations of the seismic response of long, multiple-span, highway bridge structures of the type which suffered heavy damages during the San Fernando earthquake of February 9, 1971. Linear and nonlinear mathematical modeling of this type of bridge structural system is presented. A three-dimensional elasto-plastic flexural column model suitable for modeling the coupled inelastic behavior of reinforced concrete bridge columns is described in detail. A nonlinear mathematical model for simulating the nonlinear discontinuous behavior of bridge expansion joints is also presented. Then, appropriate linear and nonlinear analytical procedures are described for determining the seismic response of this type of bridge structure. Nonlinear seismic responses are presented for three prototype long, multiple-span, reinforced concrete highway overcrossing structures. General conclusions and recommendations related to the fundamental seismic design methodology of long, multiple-span highway bridges are deduced and summarized.
