Advances in Earthquake Engineering #2: Seismic Design AIDS for Nonlinear Pushover Analysis of Reinforced Concrete and Steel Bridges

Nonlinear static monotonic (pushover) analysis has become a common practice in performance-based bridge seismic design. The popularity of pushover analysis is due to its ability to identify the failure modes and the design limit states of bridge piers and to provide the progressive collapse sequence of damaged bridges when subjected to major earthquakes. Seismic Design Aids for Nonlinear Pushover Analysis of Reinforced Concrete and Steel Bridges fills the need for a complete reference on pushover analysis for practicing engineers.

This technical reference covers the pushover analysis of reinforced concrete and steel bridges with confined and unconfined concrete column members of either circular or rectangular cross sections as well as steel members of standard shapes. It provides step-by-step procedures for pushover analysis with various nonlinear member stiffness formulations, including:

• Finite segment finite string (FSFS)
• Finite segment moment curvature (FSMC)
• Axial load moment interaction (PM)
• Constant moment ratio (CMR)
• Plastic hinge length (PHL)

Ranging from the simplest to the most sophisticated, the methods are suitable for engineers with varying levels of experience in nonlinear structural analysis.

The authors also provide a downloadable computer program, INSTRUCT (INelastic STRUCTural Analysis of Reinforced-Concrete and Steel Structures), that allows readers to perform their own pushover analyses. Numerous real-world examples demonstrate the accuracy of analytical prediction by comparing numerical results with full- or large-scale test results. A useful reference for researchers and engineers working in structural engineering, this book also offers an organized collection of nonlinear pushover analysis applications for students.

Ger, the US Federal Highway Administration bridge engineer for Florida, Puerto Rico, and the US Virgin Islands; and Cheng (emeritus, civil engineering, Missouri U. of Science and Technology) offer practicing engineers a step-by-step guide for pushover analysis, along with an executable file for a computer program to perform pushover analysis. Also called nonlinear static monotonic analysis, pushover analysis has become a common practice for performance-based bridge seismic design because it can identify failure modes and design limit states of bridge piers, and can project the progressive collapse sequence of damaged bridges when subjected to major earthquakes.
