User Interface For Performance-Based Earthquake Engineering: A Single Bent Bridge Pilot Investigation

Abstract

A graphical user interface is under development to combine nonlinear dynamic time history analysis of coupled soil-structure systems with an implementation of performance-based earthquake engineering (PBEE). The user interface builds upon previous code that allowed for analysis of piles in a soil domain under nonlinear static and nonlinear dynamic loads (OpenSeesPL). Functionality was extended for analysis of multiple suites of ground motions and combination of results probabilistically using the performance-based earthquake engineering framework developed by the Pacific Earthquake Engineering Research Center. Definition of the bridge and underlying ground configuration and material properties is greatly facilitated using this new interface. In addition, all stages of the involved analyses are conveniently executed in a systematic fashion, allowing the end user to investigate parametric or what-if scenarios on typical bridge configurations. In this paper, the main elements of this numerical framework are presented including graphical user interface elements and underlying theoretical framework. A simple bridge-ground model was developed and studied at three different levels of mesh refinement. PBEE results are computed and presented for a suite of selected ground motion records. Results show the PBEE results to be relatively insensitive to the chosen set of mesh discretization schemes.
